# Changelog
|
||||
|
||||
All notable changes to this package will be documented in this file.
|
||||
|
||||
## [0.6.0] - 2026-03-10
|
||||
|
||||
### Added
|
||||
- `check_source()` pure function for testing the full check pipeline without file I/O
|
||||
- 4 CLI pipeline tests: valid program, parse error diagnostics, cycle detection, multi-error sorted output
|
||||
- 2 `json_escape` unit tests (basic escaping + empty string)
|
||||
- 2 `inject_hmr` unit tests (with/without `</body>` tag)
|
||||
- Compile-all-examples integration test (51 `.ds` files through full pipeline)
|
||||
|
||||
### Changed
|
||||
- CLI version string updated from `"0.1.0"` to `"0.6.0"`
|
||||
|
||||
### Test Coverage
|
||||
- **7 unit tests + 1 integration test** (was 1 in v0.5.0)
|
||||
|
||||
## [0.5.0] - 2026-03-09
|
||||
|
||||
- Initial release with build, dev, check, stream, playground, add, convert, and init commands

# ws: a Node.js WebSocket library
|
||||
|
||||
[](https://www.npmjs.com/package/ws)
|
||||
[](https://github.com/websockets/ws/actions?query=workflow%3ACI+branch%3Amaster)
|
||||
[](https://coveralls.io/github/websockets/ws)
|
||||
|
||||
ws is a simple to use, blazing fast, and thoroughly tested WebSocket client and
|
||||
server implementation.
|
||||
|
||||
Passes the quite extensive Autobahn test suite: [server][server-report],
|
||||
[client][client-report].
|
||||
|
||||
**Note**: This module does not work in the browser. The client in the docs is a
|
||||
reference to a backend with the role of a client in the WebSocket communication.
|
||||
Browser clients must use the native
|
||||
[`WebSocket`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket)
|
||||
object. To make the same code work seamlessly on Node.js and the browser, you
|
||||
can use one of the many wrappers available on npm, like
|
||||
[isomorphic-ws](https://github.com/heineiuo/isomorphic-ws).

## Protocol support
|
||||
|
||||
- **HyBi drafts 07-12** (Use the option `protocolVersion: 8`)
|
||||
- **HyBi drafts 13-17** (Current default, alternatively option
|
||||
`protocolVersion: 13`)
|
||||
|
||||
## Installing
|
||||
|
||||
```
|
||||
npm install ws
|
||||
```
|
||||
|
||||
### Opt-in for performance
|
||||
|
||||
[bufferutil][] is an optional module that can be installed alongside the ws
|
||||
module:
|
||||
|
||||
```
|
||||
npm install --save-optional bufferutil
|
||||
```
|
||||
|
||||
This is a binary addon that improves the performance of certain operations such
|
||||
as masking and unmasking the data payload of the WebSocket frames. Prebuilt
|
||||
binaries are available for the most popular platforms, so you don't necessarily
|
||||
need to have a C++ compiler installed on your machine.
|
||||
|
||||
To force ws to not use bufferutil, use the
|
||||
[`WS_NO_BUFFER_UTIL`](./doc/ws.md#ws_no_buffer_util) environment variable. This
|
||||
can be useful to enhance security in systems where a user can put a package in
|
||||
the package search path of an application of another user, due to how the
|
||||
Node.js resolver algorithm works.
|
||||
|
||||
#### Legacy opt-in for performance
|
||||
|
||||
If you are running on an old version of Node.js (prior to v18.14.0), ws also
|
||||
supports the [utf-8-validate][] module:
|
||||
|
||||
```
|
||||
npm install --save-optional utf-8-validate
|
||||
```
|
||||
|
||||
This contains a binary polyfill for [`buffer.isUtf8()`][].
|
||||
|
||||
To force ws not to use utf-8-validate, use the
|
||||
[`WS_NO_UTF_8_VALIDATE`](./doc/ws.md#ws_no_utf_8_validate) environment variable.
|
||||
|
||||
## API docs
|
||||
|
||||
See [`/doc/ws.md`](./doc/ws.md) for Node.js-like documentation of ws classes and
|
||||
utility functions.
|
||||
|
||||
## WebSocket compression
|
||||
|
||||
ws supports the [permessage-deflate extension][permessage-deflate] which enables
|
||||
the client and server to negotiate a compression algorithm and its parameters,
|
||||
and then selectively apply it to the data payloads of each WebSocket message.
|
||||
|
||||
The extension is disabled by default on the server and enabled by default on the
|
||||
client. It adds a significant overhead in terms of performance and memory
|
||||
consumption so we suggest to enable it only if it is really needed.
|
||||
|
||||
Note that Node.js has a variety of issues with high-performance compression,
|
||||
where increased concurrency, especially on Linux, can lead to [catastrophic
|
||||
memory fragmentation][node-zlib-bug] and slow performance. If you intend to use
|
||||
permessage-deflate in production, it is worthwhile to set up a test
|
||||
representative of your workload and ensure Node.js/zlib will handle it with
|
||||
acceptable performance and memory usage.
|
||||
|
||||
Tuning of permessage-deflate can be done via the options defined below. You can
|
||||
also use `zlibDeflateOptions` and `zlibInflateOptions`, which is passed directly
|
||||
into the creation of [raw deflate/inflate streams][node-zlib-deflaterawdocs].
|
||||
|
||||
See [the docs][ws-server-options] for more options.
|
||||
|
||||
```js
|
||||
import WebSocket, { WebSocketServer } from 'ws';
|
||||
|
||||
const wss = new WebSocketServer({
|
||||
port: 8080,
|
||||
perMessageDeflate: {
|
||||
zlibDeflateOptions: {
|
||||
// See zlib defaults.
|
||||
chunkSize: 1024,
|
||||
memLevel: 7,
|
||||
level: 3
|
||||
},
|
||||
zlibInflateOptions: {
|
||||
chunkSize: 10 * 1024
|
||||
},
|
||||
// Other options settable:
|
||||
clientNoContextTakeover: true, // Defaults to negotiated value.
|
||||
serverNoContextTakeover: true, // Defaults to negotiated value.
|
||||
serverMaxWindowBits: 10, // Defaults to negotiated value.
|
||||
// Below options specified as default values.
|
||||
concurrencyLimit: 10, // Limits zlib concurrency for perf.
|
||||
threshold: 1024 // Size (in bytes) below which messages
|
||||
// should not be compressed if context takeover is disabled.
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
The client will only use the extension if it is supported and enabled on the
|
||||
server. To always disable the extension on the client, set the
|
||||
`perMessageDeflate` option to `false`.
|
||||
|
||||
```js
|
||||
import WebSocket from 'ws';
|
||||
|
||||
const ws = new WebSocket('ws://www.host.com/path', {
|
||||
perMessageDeflate: false
|
||||
});
|
||||
```
|
||||
|
||||
## Usage examples
|
||||
|
||||
### Sending and receiving text data
|
||||
|
||||
```js
|
||||
import WebSocket from 'ws';
|
||||
|
||||
const ws = new WebSocket('ws://www.host.com/path');
|
||||
|
||||
ws.on('error', console.error);
|
||||
|
||||
ws.on('open', function open() {
|
||||
ws.send('something');
|
||||
});
|
||||
|
||||
ws.on('message', function message(data) {
|
||||
console.log('received: %s', data);
|
||||
});
|
||||
```
|
||||
|
||||
### Sending binary data
|
||||
|
||||
```js
|
||||
import WebSocket from 'ws';
|
||||
|
||||
const ws = new WebSocket('ws://www.host.com/path');
|
||||
|
||||
ws.on('error', console.error);
|
||||
|
||||
ws.on('open', function open() {
|
||||
const array = new Float32Array(5);
|
||||
|
||||
for (var i = 0; i < array.length; ++i) {
|
||||
array[i] = i / 2;
|
||||
}
|
||||
|
||||
ws.send(array);
|
||||
});
|
||||
```
|
||||
|
||||
### Simple server
|
||||
|
||||
```js
|
||||
import { WebSocketServer } from 'ws';
|
||||
|
||||
const wss = new WebSocketServer({ port: 8080 });
|
||||
|
||||
wss.on('connection', function connection(ws) {
|
||||
ws.on('error', console.error);
|
||||
|
||||
ws.on('message', function message(data) {
|
||||
console.log('received: %s', data);
|
||||
});
|
||||
|
||||
ws.send('something');
|
||||
});
|
||||
```
|
||||
|
||||
### External HTTP/S server
|
||||
|
||||
```js
|
||||
import { createServer } from 'https';
|
||||
import { readFileSync } from 'fs';
|
||||
import { WebSocketServer } from 'ws';
|
||||
|
||||
const server = createServer({
|
||||
cert: readFileSync('/path/to/cert.pem'),
|
||||
key: readFileSync('/path/to/key.pem')
|
||||
});
|
||||
const wss = new WebSocketServer({ server });
|
||||
|
||||
wss.on('connection', function connection(ws) {
|
||||
ws.on('error', console.error);
|
||||
|
||||
ws.on('message', function message(data) {
|
||||
console.log('received: %s', data);
|
||||
});
|
||||
|
||||
ws.send('something');
|
||||
});
|
||||
|
||||
server.listen(8080);
|
||||
```
|
||||
|
||||
### Multiple servers sharing a single HTTP/S server
|
||||
|
||||
```js
|
||||
import { createServer } from 'http';
|
||||
import { WebSocketServer } from 'ws';
|
||||
|
||||
const server = createServer();
|
||||
const wss1 = new WebSocketServer({ noServer: true });
|
||||
const wss2 = new WebSocketServer({ noServer: true });
|
||||
|
||||
wss1.on('connection', function connection(ws) {
|
||||
ws.on('error', console.error);
|
||||
|
||||
// ...
|
||||
});
|
||||
|
||||
wss2.on('connection', function connection(ws) {
|
||||
ws.on('error', console.error);
|
||||
|
||||
// ...
|
||||
});
|
||||
|
||||
server.on('upgrade', function upgrade(request, socket, head) {
|
||||
const { pathname } = new URL(request.url, 'wss://base.url');
|
||||
|
||||
if (pathname === '/foo') {
|
||||
wss1.handleUpgrade(request, socket, head, function done(ws) {
|
||||
wss1.emit('connection', ws, request);
|
||||
});
|
||||
} else if (pathname === '/bar') {
|
||||
wss2.handleUpgrade(request, socket, head, function done(ws) {
|
||||
wss2.emit('connection', ws, request);
|
||||
});
|
||||
} else {
|
||||
socket.destroy();
|
||||
}
|
||||
});
|
||||
|
||||
server.listen(8080);
|
||||
```
|
||||
|
||||
### Client authentication
|
||||
|
||||
```js
|
||||
import { createServer } from 'http';
|
||||
import { WebSocketServer } from 'ws';
|
||||
|
||||
function onSocketError(err) {
|
||||
console.error(err);
|
||||
}
|
||||
|
||||
const server = createServer();
|
||||
const wss = new WebSocketServer({ noServer: true });
|
||||
|
||||
wss.on('connection', function connection(ws, request, client) {
|
||||
ws.on('error', console.error);
|
||||
|
||||
ws.on('message', function message(data) {
|
||||
console.log(`Received message ${data} from user ${client}`);
|
||||
});
|
||||
});
|
||||
|
||||
server.on('upgrade', function upgrade(request, socket, head) {
|
||||
socket.on('error', onSocketError);
|
||||
|
||||
// This function is not defined on purpose. Implement it with your own logic.
|
||||
authenticate(request, function next(err, client) {
|
||||
if (err || !client) {
|
||||
socket.write('HTTP/1.1 401 Unauthorized\r\n\r\n');
|
||||
socket.destroy();
|
||||
return;
|
||||
}
|
||||
|
||||
socket.removeListener('error', onSocketError);
|
||||
|
||||
wss.handleUpgrade(request, socket, head, function done(ws) {
|
||||
wss.emit('connection', ws, request, client);
|
||||
});
|
||||
});
|
||||
});
|
||||
|
||||
server.listen(8080);
|
||||
```
|
||||
|
||||
Also see the provided [example][session-parse-example] using `express-session`.
|
||||
|
||||
### Server broadcast
|
||||
|
||||
A client WebSocket broadcasting to all connected WebSocket clients, including
|
||||
itself.
|
||||
|
||||
```js
|
||||
import WebSocket, { WebSocketServer } from 'ws';
|
||||
|
||||
const wss = new WebSocketServer({ port: 8080 });
|
||||
|
||||
wss.on('connection', function connection(ws) {
|
||||
ws.on('error', console.error);
|
||||
|
||||
ws.on('message', function message(data, isBinary) {
|
||||
wss.clients.forEach(function each(client) {
|
||||
if (client.readyState === WebSocket.OPEN) {
|
||||
client.send(data, { binary: isBinary });
|
||||
}
|
||||
});
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
A client WebSocket broadcasting to every other connected WebSocket clients,
|
||||
excluding itself.
|
||||
|
||||
```js
|
||||
import WebSocket, { WebSocketServer } from 'ws';
|
||||
|
||||
const wss = new WebSocketServer({ port: 8080 });
|
||||
|
||||
wss.on('connection', function connection(ws) {
|
||||
ws.on('error', console.error);
|
||||
|
||||
ws.on('message', function message(data, isBinary) {
|
||||
wss.clients.forEach(function each(client) {
|
||||
if (client !== ws && client.readyState === WebSocket.OPEN) {
|
||||
client.send(data, { binary: isBinary });
|
||||
}
|
||||
});
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
### Round-trip time
|
||||
|
||||
```js
|
||||
import WebSocket from 'ws';
|
||||
|
||||
const ws = new WebSocket('wss://websocket-echo.com/');
|
||||
|
||||
ws.on('error', console.error);
|
||||
|
||||
ws.on('open', function open() {
|
||||
console.log('connected');
|
||||
ws.send(Date.now());
|
||||
});
|
||||
|
||||
ws.on('close', function close() {
|
||||
console.log('disconnected');
|
||||
});
|
||||
|
||||
ws.on('message', function message(data) {
|
||||
console.log(`Round-trip time: ${Date.now() - data} ms`);
|
||||
|
||||
setTimeout(function timeout() {
|
||||
ws.send(Date.now());
|
||||
}, 500);
|
||||
});
|
||||
```
|
||||
|
||||
### Use the Node.js streams API
|
||||
|
||||
```js
|
||||
import WebSocket, { createWebSocketStream } from 'ws';
|
||||
|
||||
const ws = new WebSocket('wss://websocket-echo.com/');
|
||||
|
||||
const duplex = createWebSocketStream(ws, { encoding: 'utf8' });
|
||||
|
||||
duplex.on('error', console.error);
|
||||
|
||||
duplex.pipe(process.stdout);
|
||||
process.stdin.pipe(duplex);
|
||||
```
|
||||
|
||||
### Other examples
|
||||
|
||||
For a full example with a browser client communicating with a ws server, see the
|
||||
examples folder.
|
||||
|
||||
Otherwise, see the test cases.
|
||||
|
||||
## FAQ
|
||||
|
||||
### How to get the IP address of the client?
|
||||
|
||||
The remote IP address can be obtained from the raw socket.
|
||||
|
||||
```js
|
||||
import { WebSocketServer } from 'ws';
|
||||
|
||||
const wss = new WebSocketServer({ port: 8080 });
|
||||
|
||||
wss.on('connection', function connection(ws, req) {
|
||||
const ip = req.socket.remoteAddress;
|
||||
|
||||
ws.on('error', console.error);
|
||||
});
|
||||
```
|
||||
|
||||
When the server runs behind a proxy like NGINX, the de-facto standard is to use
|
||||
the `X-Forwarded-For` header.
|
||||
|
||||
```js
|
||||
wss.on('connection', function connection(ws, req) {
|
||||
const ip = req.headers['x-forwarded-for'].split(',')[0].trim();
|
||||
|
||||
ws.on('error', console.error);
|
||||
});
|
||||
```
|
||||
|
||||
### How to detect and close broken connections?
|
||||
|
||||
Sometimes, the link between the server and the client can be interrupted in a
|
||||
way that keeps both the server and the client unaware of the broken state of the
|
||||
connection (e.g. when pulling the cord).
|
||||
|
||||
In these cases, ping messages can be used as a means to verify that the remote
|
||||
endpoint is still responsive.
|
||||
|
||||
```js
|
||||
import { WebSocketServer } from 'ws';
|
||||
|
||||
function heartbeat() {
|
||||
this.isAlive = true;
|
||||
}
|
||||
|
||||
const wss = new WebSocketServer({ port: 8080 });
|
||||
|
||||
wss.on('connection', function connection(ws) {
|
||||
ws.isAlive = true;
|
||||
ws.on('error', console.error);
|
||||
ws.on('pong', heartbeat);
|
||||
});
|
||||
|
||||
const interval = setInterval(function ping() {
|
||||
wss.clients.forEach(function each(ws) {
|
||||
if (ws.isAlive === false) return ws.terminate();
|
||||
|
||||
ws.isAlive = false;
|
||||
ws.ping();
|
||||
});
|
||||
}, 30000);
|
||||
|
||||
wss.on('close', function close() {
|
||||
clearInterval(interval);
|
||||
});
|
||||
```
|
||||
|
||||
Pong messages are automatically sent in response to ping messages as required by
|
||||
the spec.
|
||||
|
||||
Just like the server example above, your clients might as well lose connection
|
||||
without knowing it. You might want to add a ping listener on your clients to
|
||||
prevent that. A simple implementation would be:
|
||||
|
||||
```js
|
||||
import WebSocket from 'ws';
|
||||
|
||||
function heartbeat() {
|
||||
clearTimeout(this.pingTimeout);
|
||||
|
||||
// Use `WebSocket#terminate()`, which immediately destroys the connection,
|
||||
// instead of `WebSocket#close()`, which waits for the close timer.
|
||||
// Delay should be equal to the interval at which your server
|
||||
// sends out pings plus a conservative assumption of the latency.
|
||||
this.pingTimeout = setTimeout(() => {
|
||||
this.terminate();
|
||||
}, 30000 + 1000);
|
||||
}
|
||||
|
||||
const client = new WebSocket('wss://websocket-echo.com/');
|
||||
|
||||
client.on('error', console.error);
|
||||
client.on('open', heartbeat);
|
||||
client.on('ping', heartbeat);
|
||||
client.on('close', function clear() {
|
||||
clearTimeout(this.pingTimeout);
|
||||
});
|
||||
```
|
||||
|
||||
### How to connect via a proxy?
|
||||
|
||||
Use a custom `http.Agent` implementation like [https-proxy-agent][] or
|
||||
[socks-proxy-agent][].

# DreamStack Hardware Explorations
|
||||
|
||||
> Research notes on form factors, display technologies, and touch input methods for DreamStack-powered surfaces.
|
||||
|
||||
---
|
||||
|
||||
## 1. USB Dongle (Chromecast-like)
|
||||
|
||||
The DreamStack relay protocol + delta codec already does 90% of the work. A dongle receives the bitstream and outputs to HDMI.
|
||||
|
||||
### Path A: ESP32-S3 HDMI Dongle (~$15 DIY)
|
||||
|
||||
| Component | Part | Cost |
|
||||
|-----------|------|------|
|
||||
| SoC | ESP32-S3-WROOM-1 (N16R8) | ~$4 |
|
||||
| HDMI output | CH7035B or ADV7513 HDMI encoder IC | ~$3 |
|
||||
| USB-C power | Standard power-only connector | ~$0.50 |
|
||||
| PCB + passives | Custom PCB (JLCPCB) | ~$5 for 5 boards |
|
||||
| HDMI connector | Type-A male or mini-HDMI | ~$1 |
|
||||
|
||||
- ESP32-S3 LCD parallel interface → HDMI encoder IC → HDMI out
|
||||
- WiFi connects to DreamStack relay, receives delta-compressed frames
|
||||
- Resolution limit: ~480×320 smooth, 800×600 at lower FPS
|
||||
- Input via BLE HID remote or HDMI CEC (pin 13)
|
||||
|
||||
### Path B: Linux Stick / Allwinner (~$25-40)
|
||||
|
||||
MangoPi MQ-Pro / Radxa Zero form factor:
|
||||
|
||||
| Component | Part | Cost |
|
||||
|-----------|------|------|
|
||||
| SoC | Allwinner H616/H618 (HDMI built-in) | ~$15 module |
|
||||
| RAM | 512MB DDR3 onboard | included |
|
||||
| WiFi | RTL8723CS | ~$3 |
|
||||
| Storage | 8GB eMMC or SD | ~$3 |
|
||||
|
||||
- Runs minimal Linux (Buildroot), headless browser or C receiver writing to `/dev/fb0`
|
||||
- Native HDMI — no encoder IC needed
|
||||
- Full DreamStack JS runtime in headless Chromium/WPE-WebKit
|
||||
- CEC for remote control
|
||||
|
||||
### Path C: Pi Zero 2 W (~$15, recommended MVP)
|
||||
|
||||
Best for proving the concept immediately — $15, mini-HDMI out, WiFi, runs DreamStack natively.
|
||||
|
||||

|
||||
## 3. Touch Input Technologies
|
||||
|
||||
Ranked from fastest to slowest latency:
|
||||
|
||||
### 3a. Piezoelectric Sensors (<1ms, ~$7)
|
||||
|
||||
Stick 3-4 piezo discs on the **back** of the wall. Finger taps create vibrations; time-difference-of-arrival (TDOA) triangulates X,Y.
|
||||
|
||||
| Part | Cost |
|
||||
|------|------|
|
||||
| 4× piezo disc (35mm) | ~$2 |
|
||||
| ESP32-S3 (built-in ADC, 40kHz+ sampling) | ~$5 |
|
||||
|
||||
```
|
||||
Wall (drywall, glass, wood, whiteboard)
|
||||
┌───────────────────────────────────────┐
|
||||
│ P1 ● ● P2 │
|
||||
│ 👆 TAP │
|
||||
│ P3 ● ● P4 │
|
||||
└───────────────────────────────────────┘
|
||||
└────── ESP32 (TDOA → x,y) ─────┘
|
||||
```
|
||||
|
||||
**Pros:** Near-instant, invisible, dirt cheap, works through paint
|
||||
**Cons:** Only detects **taps** (not drag/hover), needs hard surface
|
||||
|
||||
---
|
||||
|
||||
### 3b. Capacitive Wire/Paint Grid (1-3ms, ~$21 DIY)
|
||||
|
||||
Grid of conductors (copper tape or conductive paint) behind the wall. Measures capacitance change when a finger approaches.
|
||||
|
||||
| Part | Cost |
|
||||
|------|------|
|
||||
| Copper tape grid (30 channels) or graphite paint | ~$10 |
|
||||
| MPR121 capacitive controller ×3 | ~$6 |
|
||||
| ESP32 | ~$5 |
|
||||
|
||||
**Supports:** Touch ✅ Drag ✅ Multi-touch ✅ Hover (~1-2cm) ✅
|
||||
**Resolution:** Depends on grid pitch — 3cm pitch ≈ 30×40 nodes over 100"
|
||||
|
||||
#### How Mutual Capacitance Works
|
||||
|
||||
Two layers of conductors (rows + columns) cross each other, separated by a thin insulator. Each intersection forms a capacitor. A finger near any intersection absorbs electric field, reducing measured capacitance.
|
||||
|
||||
The controller scans one row at a time (AC drive), reads all columns simultaneously. Full scan of 30×40 grid: ~0.5-1ms. Continuous scanning gives automatic drag/swipe detection. Sub-pixel interpolation from adjacent node readings gives ~1mm accuracy from 5mm pitch.
|
||||
|
||||
#### Recommended ICs
|
||||
|
||||
| IC | Grid Size | Touch Points | Price |
|
||||
|----|-----------|-------------|-------|
|
||||
| MTCH6303 (Microchip) | 15×49 | 10 | ~$5 |
|
||||
| IQS7211A (Azoteq) | 15×22 | 5 | ~$3 |
|
||||
| GT911 (Goodix) | 26×14 | 5 | ~$2 |
|
||||
| FT5x06 (FocalTech) | 24×14 | 5 | ~$2 |
|
||||
|
||||
---
|
||||
|
||||
### 3c. FTIR — Frustrated Total Internal Reflection (3-8ms, ~$110-250)
|
||||
|
||||
Acrylic sheet on wall with IR LEDs on edges (total internal reflection). Finger touch "frustrates" the reflection → bright spots detected by IR camera.
|
||||
|
||||
| Part | Cost |
|
||||
|------|------|
|
||||
| 4mm acrylic sheet (100") | ~$80-150 |
|
||||
| IR LED strip (850nm) on edges | ~$10 |
|
||||
| IR camera (120fps, no IR filter) | ~$15 |
|
||||
| ESP32-S3 or Pi | ~$5-75 |
|
||||
|
||||
**Pros:** Multi-touch, precise, pressure-sensitive (brighter blob = more pressure)
|
||||
**Cons:** Needs smooth flat surface (acrylic)
|
||||
|
||||
---
|
||||
|
||||
### 3d. IR Touch Frame (8-15ms, ~$250-500)
|
||||
|
||||
Aluminum frame with IR LEDs + sensors on 4 edges. Finger breaks IR beams → X,Y.
|
||||
|
||||
| Size | Price | Touch Points |
|
||||
|------|-------|-------------|
|
||||
| 65" | ~$250 | 6-10 pt |
|
||||
| 82" | ~$350 | 10-20 pt |
|
||||
| 100" | ~$500 | 10-20 pt |
|
||||
| 120"+ | ~$800+ | 20+ pt |
|
||||
|
||||
Premium: Neonode zForce (~6-8ms, 200Hz). Budget: generic Chinese frames (~15-30ms, 100Hz).
|
||||
|
||||
**Pros:** USB HID plug-and-play, works on any surface
|
||||
**Cons:** Physical border/bezel on wall
|
||||
|
||||
---
|
||||
|
||||
### 3e. Depth Camera (15-30ms, ~$80-450)
|
||||
|
||||
| Camera | FPS | Latency | Range | Price |
|
||||
|--------|-----|---------|-------|-------|
|
||||
| **Intel RealSense D405** | 90fps | ~11ms | 7cm-50cm | ~$80 |
|
||||
| RealSense D435i | 90fps | ~11ms | 10cm-10m | ~$200 |
|
||||
| OAK-D SR (Short Range) | 60fps | ~12ms | 2cm-100cm | ~$150 |
|
||||
| OAK-D Pro | 30fps depth | ~15ms | 20cm-15m | ~$200 |
|
||||
| Stereolabs ZED Mini | 100fps | ~10ms | 10cm-12m | ~$300 |
|
||||
| Stereolabs ZED X Mini | 120fps | ~8ms | 10cm-15m | ~$450 |
|
||||
| Orbbec Gemini 2 | 60fps | ~16ms | 15cm-10m | ~$130 |
|
||||
|
||||
**RealSense D405** is ideal for wall touch — 90fps hardware stereo depth, 7cm minimum distance, global shutter. No ML needed for touch detection: just threshold the depth map (`depth < 5mm → TOUCH`, `< 150mm → HOVER`).
|
||||
|
||||
Layer MediaPipe on top (parallel) for gesture classification.
|
||||
|
||||
---
|
||||
|
||||
### 3f. Hybrid: Best of All Worlds
|
||||
|
||||
| Input | Method | Latency |
|
||||
|-------|--------|---------|
|
||||
| Tap detection + pressure | Piezo (4 corners) | <1ms |
|
||||
| Touch + drag + hover | Capacitive grid | 1-3ms |
|
||||
| Hand gestures (air) | RealSense D405 | ~15ms |
|
||||
|
||||
---
|
||||
|
||||
## 4. Gesture / Hand Tracking
|
||||
|
||||
### DIY Approaches (Ultraleap alternative)
|
||||
|
||||
#### Stereo IR Camera + MediaPipe (~$30-50)
|
||||
|
||||
Two OV2710 IR USB cameras (stereo pair, ~$15 each) + 850nm IR LED strip (~$5). MediaPipe Hands on Pi 5 or Jetson: 21 landmarks per hand, 30-120fps. Stereo triangulation gives Z. **Latency: ~20-30ms.**
|
||||
|
||||
#### Single Depth Camera (~$80-150)
|
||||
|
||||
Use RealSense D405 or OAK-D SR (see above). Hardware depth gives Z-distance from wall.
|
||||
|
||||
#### ESP32-S3 + IR Matrix (~$20, lowest latency)
|
||||
|
||||
IR LEDs flood the area in front of the wall. 2-3 IR cameras do blob detection at 120fps on ESP32-S3. Z estimated from blob size. No ML needed. **Latency: 5-10ms.**
|
||||

|
||||
|
||||
## 5. Conductive Paint Recipes
|
||||
|
||||
For capacitive grid electrodes painted directly on walls.
|
||||
|
||||
### Graphite Paint (easiest, ~$5)
|
||||
|
||||
| Ingredient | Amount | Source |
|
||||
|-----------|--------|--------|
|
||||
| Graphite powder (<45μm) | 3 tbsp | Art supply, Amazon (~$8/lb) |
|
||||
| PVA glue (white school glue) | 2 tbsp | Any store |
|
||||
| Water | 1 tbsp | Tap |
|
||||
|
||||
~60% graphite, 30% glue, 10% water by volume. **Resistance: ~500-2000 Ω/sq.** Good enough for capacitive sensing.
|
||||
|
||||
### Carbon Black + Acrylic (~$15)
|
||||
|
||||
20-25% carbon black powder (conductive grade) in 75-80% acrylic medium. **Resistance: ~200-800 Ω/sq.** Better adhesion. Wear mask + gloves.
|
||||
|
||||
### Nickel Paint (~$20)
|
||||
|
||||
MG Chemicals 841, premade. **Resistance: ~5-50 Ω/sq.** Mid-range.
|
||||
|
||||
### Silver Paint (~$30-50)
|
||||
|
||||
Premade: Bare Conductive (~$25/50ml), MG Chemicals 842.
|
||||
DIY: 70-80% silver flake powder (<10μm), 15-20% acrylic medium, 5-10% butyl acetate.
|
||||
**Resistance: ~0.5-5 Ω/sq.** Near-wire conductivity.
|
||||
|
||||
### For capacitive sensing: graphite is sufficient
|
||||
|
||||
Capacitive touch doesn't need low resistance — just enough conductivity to couple with a finger. Paint lines with tape masking at 3-5cm spacing.
|
||||
|
||||
---
|
||||
|
||||
## 6. Pixel Paint — Paint-On Displays
|
||||
|
||||
### Electroluminescent (EL) Paint Display
|
||||
|
||||
Real and buildable. A stack of painted layers that glow when AC voltage is applied.
|
||||
|
||||
```
|
||||
Layer stack (painted in order):
|
||||
|
||||
5. Clear topcoat
|
||||
4. Transparent conductor (PEDOT:PSS) ← rows
|
||||
3. Phosphor layer (ZnS:Cu in acrylic) ← glows
|
||||
2. Dielectric (BaTiO₃ in acrylic) ← insulator
|
||||
1. Base conductor (silver/carbon paint) ← columns
|
||||
─── Wall surface ───
|
||||
```
|
||||
|
||||
Row/column intersection = one pixel. AC across a specific row+column → only that intersection glows (passive matrix).
|
||||
|
||||
| Layer | Material | Cost/m² |
|
||||
|-------|----------|---------|
|
||||
| Base conductor (columns) | Silver paint, painted in strips | ~$50 |
|
||||
| Dielectric | Barium titanate (BaTiO₃) in acrylic | ~$30 |
|
||||
| Phosphor | ZnS:Cu powder in acrylic | ~$20 |
|
||||
| Top conductor (rows) | PEDOT:PSS | ~$40 |
|
||||
| Driver electronics | HV507 shift registers + ESP32 | ~$30 |
|
||||
| **Total** | | **~$170/m²** |
|
||||
|
||||
#### Resolution at different pitches
|
||||
|
||||
| Pixel Pitch | Pixels (100" wall) | Comparable To |
|
||||
|------------|---------------------|---------------|
|
||||
| 20mm | 110×65 = 7,150 | LED sign |
|
||||
| 10mm | 220×130 = 28,600 | Scoreboard |
|
||||
| 5mm | 440×260 = 114,400 | ~400×260 display ✅ |
|
||||
| 2mm | 1100×650 = 715,000 | Near SD |
|
||||
|
||||
At 5mm pitch: 440×260 — enough for DreamStack UIs, dashboards, snake game.
|
||||
|
||||
#### Color
|
||||
|
||||
- ZnS:Cu → green (brightest)
|
||||
- ZnS:Cu,Mn → amber/orange
|
||||
- ZnS:Cu,Al → blue-green
|
||||
- Full RGB requires 3 sub-pixels per pixel (3× driver count)
|
||||
- Monochrome green is practical and looks great
|
||||
|
||||
#### Built-in touch (free!)
|
||||
|
||||
The row/column electrodes double as capacitive sensing electrodes via time-multiplexing:
|
||||
1. **Sense phase** (1ms): measure capacitance = touch position
|
||||
2. **Drive phase** (15ms): apply AC = illuminate pixels
|
||||
|
||||
Same paint layers, no extra hardware.
|
||||
|
||||
#### Driver IC
|
||||
|
||||
HV507 — 64-channel high-voltage shift register. Drives 100V+ outputs from 3.3V SPI. Chain several for full display.
|
||||
|
||||
### Other Display Paint Technologies (Future)
|
||||
|
||||
| Technology | Status | Color | Speed |
|
||||
|-----------|--------|-------|-------|
|
||||
| Electrochromic (PEDOT:PSS, WO₃) | Real | Grayscale | 1-30s (too slow for video) |
|
||||
| Thermochromic + resistive grid | Hackable | Limited | 1-5s |
|
||||
| Perovskite spray-on LEDs | Lab only | Full color | ~ms |
|
||||
| QD-LED inkjet | Lab only | Full color | ~ms |
|
||||
|
||||
Perovskite / QD-LED spray-on is the future (~2028-2030) but not available today.

## 9. DreamStack Integration
|
||||
|
||||
All touch methods feed into the existing relay protocol:
|
||||
|
||||
```
|
||||
Touch sensor (any method above)
|
||||
→ ESP32 or Pi reads touch events
|
||||
→ Encodes as DreamStack protocol:
|
||||
0x01 Pointer move (x, y)
|
||||
0x02 Pointer down (x, y, buttons)
|
||||
0x03 Pointer up
|
||||
0x10 KeyDown (keyCode)
|
||||
0x20 Hover (x, y, z_distance) ← new
|
||||
0x21 Swipe (direction, velocity) ← new
|
||||
0x22 Pinch/Grab (state) ← new
|
||||
→ WebSocket → DreamStack relay
|
||||
→ App receives as signal updates
|
||||
```
|
||||
|
||||
DreamStack syntax for handling:
|
||||
|
||||
```
|
||||
on hover(ev) -> opacity = lerp(0.5, 1.0, ev.z)
|
||||
on swipe(ev) -> navigate(if ev.dir == "left" then "/next" else "/prev")
|
||||
on grab(ev) -> scale = if ev.closed then 0.9 else 1.0
|
||||
```

# chrome-remote-interface
|
||||
|
||||
[](https://github.com/cyrus-and/chrome-remote-interface/actions?query=workflow:CI)
|
||||
|
||||
[Chrome Debugging Protocol] interface that helps to instrument Chrome (or any
|
||||
other suitable [implementation](#implementations)) by providing a simple
|
||||
abstraction of commands and notifications using a straightforward JavaScript
|
||||
API.
|
||||
|
||||
## Sample API usage
|
||||
|
||||
The following snippet loads `https://github.com` and dumps every request made:
|
||||
|
||||
```js
|
||||
const CDP = require('chrome-remote-interface');
|
||||
|
||||
async function example() {
|
||||
let client;
|
||||
try {
|
||||
// connect to endpoint
|
||||
client = await CDP();
|
||||
// extract domains
|
||||
const {Network, Page} = client;
|
||||
// setup handlers
|
||||
Network.requestWillBeSent((params) => {
|
||||
console.log(params.request.url);
|
||||
});
|
||||
// enable events then start!
|
||||
await Network.enable();
|
||||
await Page.enable();
|
||||
await Page.navigate({url: 'https://github.com'});
|
||||
await Page.loadEventFired();
|
||||
} catch (err) {
|
||||
console.error(err);
|
||||
} finally {
|
||||
if (client) {
|
||||
await client.close();
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
example();
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Installation
|
||||
|
||||
npm install chrome-remote-interface
|
||||
|
||||
Install globally (`-g`) to just use the [bundled client](#bundled-client).
|
||||
|
||||
## Implementations
|
||||
|
||||
This module should work with every application implementing the
|
||||
[Chrome Debugging Protocol]. In particular, it has been tested against the
|
||||
following implementations:
|
||||
|
||||
Implementation | Protocol version | [Protocol] | [List] | [New] | [Activate] | [Close] | [Version]
|
||||
---------------------------|--------------------|------------|--------|-------|------------|---------|-----------
|
||||
[Chrome][1.1] | [tip-of-tree][1.2] | yes¹ | yes | yes | yes | yes | yes
|
||||
[Opera][2.1] | [tip-of-tree][2.2] | yes | yes | yes | yes | yes | yes
|
||||
[Node.js][3.1] ([v6.3.0]+) | [node][3.2] | yes | no | no | no | no | yes
|
||||
[Safari (iOS)][4.1] | [*partial*][4.2] | no | yes | no | no | no | no
|
||||
[Edge][5.1] | [*partial*][5.2] | yes | yes | no | no | no | yes
|
||||
[Firefox (Nightly)][6.1] | [*partial*][6.2] | yes | yes | no | yes | yes | yes
|
||||
|
||||
¹ Not available on [Chrome for Android][chrome-mobile-protocol], hence a local version of the protocol must be used.

|
||||
|
||||
The meaning of *target* varies according to the implementation, for example,
|
||||
each Chrome tab represents a target whereas for Node.js a target is the
|
||||
currently inspected script.
|
||||
|
||||
## Setup
|
||||
|
||||
An instance of either Chrome itself or another implementation needs to be
|
||||
running on a known port in order to use this module (defaults to
|
||||
`localhost:9222`).
|
||||
|
||||
### Chrome/Chromium
|
||||
|
||||
#### Desktop
|
||||
|
||||
Start Chrome with the `--remote-debugging-port` option, for example:
|
||||
|
||||
google-chrome --remote-debugging-port=9222
|
||||
|
||||
##### Headless
|
||||
|
||||
Since version 59, additionally use the `--headless` option, for example:
|
||||
|
||||
google-chrome --headless --remote-debugging-port=9222
|
||||
|
||||
#### Android
|
||||
|
||||
Plug the device and make sure to authorize the connection from the device itself. Then
|
||||
enable the port forwarding, for example:
|
||||
|
||||
adb -d forward tcp:9222 localabstract:chrome_devtools_remote
|
||||
|
||||
After that you should be able to use `http://127.0.0.1:9222` as usual, but note that in
|
||||
Android, Chrome does not have its own protocol available, so a local version must be used.
|
||||
See [here](#chrome-debugging-protocol-versions) for more information.
|
||||
|
||||
##### WebView
|
||||
|
||||
In order to be inspectable, a WebView must
|
||||
be [configured for debugging][webview] and the corresponding process ID must be
|
||||
known. There are several ways to obtain it, for example:
|
||||
|
||||
adb shell grep -a webview_devtools_remote /proc/net/unix
|
||||
|
||||
Finally, port forwarding can be enabled as follows:
|
||||
|
||||
adb forward tcp:9222 localabstract:webview_devtools_remote_<pid>
|
||||
|
||||
[webview]: https://developers.google.com/web/tools/chrome-devtools/remote-debugging/webviews#configure_webviews_for_debugging
|
||||
|
||||
### Opera
|
||||
|
||||
Start Opera with the `--remote-debugging-port` option, for example:
|
||||
|
||||
opera --remote-debugging-port=9222
|
||||
|
||||
### Node.js
|
||||
|
||||
Start Node.js with the `--inspect` option, for example:
|
||||
|
||||
node --inspect=9222 script.js
|
||||
|
||||
### Safari (iOS)
|
||||
|
||||
Install and run the [iOS WebKit Debug Proxy][iwdp]. Then use it with the `local`
|
||||
option set to `true` to use the local version of the protocol or pass a custom
|
||||
descriptor upon connection (`protocol` option).
|
||||
|
||||
[iwdp]: https://github.com/google/ios-webkit-debug-proxy
|
||||
|
||||
### Edge
|
||||
|
||||
Start Edge with the `--devtools-server-port` option, for example:
|
||||
|
||||
MicrosoftEdge.exe --devtools-server-port 9222 about:blank
|
||||
|
||||
Please find more information [here][edge-devtools].
|
||||
|
||||
[edge-devtools]: https://docs.microsoft.com/en-us/microsoft-edge/devtools-protocol/
|
||||
|
||||
### Firefox (Nightly)
|
||||
|
||||
Start Firefox with the `--remote-debugging-port` option, for example:
|
||||
|
||||
firefox --remote-debugging-port 9222
|
||||
|
||||
Bear in mind that this is an experimental feature of Firefox.
|
||||
|
||||
## Bundled client
|
||||
|
||||
This module comes with a bundled client application that can be used to
|
||||
interactively control a remote instance.
|
||||
|
||||
### Target management
|
||||
|
||||
The bundled client exposes subcommands to interact with the HTTP frontend
|
||||
(e.g., [List](#cdplistoptions-callback), [New](#cdpnewoptions-callback), etc.),
|
||||
run with `--help` to display the list of available options.
|
||||
|
||||
Here are some examples:
|
||||
|
||||
```js
|
||||
$ chrome-remote-interface new 'http://example.com'
|
||||
{
|
||||
"description": "",
|
||||
"devtoolsFrontendUrl": "/devtools/inspector.html?ws=localhost:9222/devtools/page/b049bb56-de7d-424c-a331-6ae44cf7ae01",
|
||||
"id": "b049bb56-de7d-424c-a331-6ae44cf7ae01",
|
||||
"thumbnailUrl": "/thumb/b049bb56-de7d-424c-a331-6ae44cf7ae01",
|
||||
"title": "",
|
||||
"type": "page",
|
||||
"url": "http://example.com/",
|
||||
"webSocketDebuggerUrl": "ws://localhost:9222/devtools/page/b049bb56-de7d-424c-a331-6ae44cf7ae01"
|
||||
}
|
||||
$ chrome-remote-interface close 'b049bb56-de7d-424c-a331-6ae44cf7ae01'
|
||||
```
|
||||
|
||||
### Inspection
|
||||
|
||||
Using the `inspect` subcommand it is possible to perform [command execution](#clientdomainmethodparams-callback)
|
||||
and [event binding](#clientdomaineventcallback) in a REPL fashion that provides completion.
|
||||
|
||||
Here is a sample session:
|
||||
|
||||
```js
|
||||
$ chrome-remote-interface inspect
|
||||
>>> Runtime.evaluate({expression: 'window.location.toString()'})
|
||||
{ result: { type: 'string', value: 'about:blank' } }
|
||||
>>> Page.enable()
|
||||
{}
|
||||
>>> Page.loadEventFired(console.log)
|
||||
[Function]
|
||||
>>> Page.navigate({url: 'https://github.com'})
|
||||
{ frameId: 'E1657E22F06E6E0BE13DFA8130C20298',
|
||||
loaderId: '439236ADE39978F98C20E8939A32D3A5' }
|
||||
>>> { timestamp: 7454.721299 } // from Page.loadEventFired
|
||||
>>> Runtime.evaluate({expression: 'window.location.toString()'})
|
||||
{ result: { type: 'string', value: 'https://github.com/' } }
|
||||
```
|
||||
|
||||
Additionally there are some custom commands available:
|
||||
|
||||
```js
|
||||
>>> .help
|
||||
[...]
|
||||
.reset Remove all the registered event handlers
|
||||
.target Display the current target
|
||||
```
|
||||
|
||||
## Embedded documentation
|
||||
|
||||
In both the REPL and the regular API every object of the protocol is *decorated*
|
||||
with the meta information found within the descriptor. In addition The
|
||||
`category` field is added, which determines if the member is a `command`, an
|
||||
`event` or a `type`.
|
||||
|
||||
For example to learn how to call `Page.navigate`:
|
||||
|
||||
```js
|
||||
>>> Page.navigate
|
||||
{ [Function]
|
||||
category: 'command',
|
||||
parameters: { url: { type: 'string', description: 'URL to navigate the page to.' } },
|
||||
returns:
|
||||
[ { name: 'frameId',
|
||||
'$ref': 'FrameId',
|
||||
hidden: true,
|
||||
description: 'Frame id that will be navigated.' } ],
|
||||
description: 'Navigates current page to the given URL.',
|
||||
handlers: [ 'browser', 'renderer' ] }
|
||||
```
|
||||
|
||||
To learn about the parameters returned by the `Network.requestWillBeSent` event:
|
||||
|
||||
```js
|
||||
>>> Network.requestWillBeSent
|
||||
{ [Function]
|
||||
category: 'event',
|
||||
description: 'Fired when page is about to send HTTP request.',
|
||||
parameters:
|
||||
{ requestId: { '$ref': 'RequestId', description: 'Request identifier.' },
|
||||
frameId:
|
||||
{ '$ref': 'Page.FrameId',
|
||||
description: 'Frame identifier.',
|
||||
hidden: true },
|
||||
loaderId: { '$ref': 'LoaderId', description: 'Loader identifier.' },
|
||||
documentURL:
|
||||
{ type: 'string',
|
||||
description: 'URL of the document this request is loaded for.' },
|
||||
request: { '$ref': 'Request', description: 'Request data.' },
|
||||
timestamp: { '$ref': 'Timestamp', description: 'Timestamp.' },
|
||||
wallTime:
|
||||
{ '$ref': 'Timestamp',
|
||||
hidden: true,
|
||||
description: 'UTC Timestamp.' },
|
||||
initiator: { '$ref': 'Initiator', description: 'Request initiator.' },
|
||||
redirectResponse:
|
||||
{ optional: true,
|
||||
'$ref': 'Response',
|
||||
description: 'Redirect response data.' },
|
||||
type:
|
||||
{ '$ref': 'Page.ResourceType',
|
||||
optional: true,
|
||||
hidden: true,
|
||||
description: 'Type of this resource.' } } }
|
||||
```
|
||||
|
||||
To inspect the `Network.Request` (note that unlike commands and events, types
|
||||
are named in upper camel case) type:
|
||||
|
||||
```js
|
||||
>>> Network.Request
|
||||
{ category: 'type',
|
||||
id: 'Request',
|
||||
type: 'object',
|
||||
description: 'HTTP request data.',
|
||||
properties:
|
||||
{ url: { type: 'string', description: 'Request URL.' },
|
||||
method: { type: 'string', description: 'HTTP request method.' },
|
||||
headers: { '$ref': 'Headers', description: 'HTTP request headers.' },
|
||||
postData:
|
||||
{ type: 'string',
|
||||
optional: true,
|
||||
description: 'HTTP POST request data.' },
|
||||
mixedContentType:
|
||||
{ optional: true,
|
||||
type: 'string',
|
||||
enum: [Object],

## Chrome Debugging Protocol versions
|
||||
|
||||
By default `chrome-remote-interface` *asks* the remote instance to provide its
|
||||
own protocol.
|
||||
|
||||
This behavior can be changed by setting the `local` option to `true`
|
||||
upon [connection](#cdpoptions-callback), in which case the [local version] of
|
||||
the protocol descriptor is used. This file is manually updated from time to time
|
||||
using `scripts/update-protocol.sh` and pushed to this repository.
|
||||
|
||||
To further override the above behavior there are basically two options:
|
||||
|
||||
- pass a custom protocol descriptor upon [connection](#cdpoptions-callback)
|
||||
(`protocol` option);
|
||||
|
||||
- use the *raw* version of the [commands](#clientsendmethod-params-callback)
|
||||
and [events](#event-domainmethod) interface to use bleeding-edge features that
|
||||
do not appear in the [local version] of the protocol descriptor;
|
||||
|
||||
[local version]: lib/protocol.json
|
||||
|
||||
## Browser usage
|
||||
|
||||
This module is able to run within a web context, with obvious limitations
|
||||
though, namely external HTTP requests
|
||||
([List](#cdplistoptions-callback), [New](#cdpnewoptions-callback), etc.) cannot
|
||||
be performed directly, for this reason the user must provide a global
|
||||
`criRequest` in order to use them:
|
||||
|
||||
```js
|
||||
function criRequest(options, callback) {}
|
||||
```
|
||||
|
||||
`options` is the same object used by the Node.js `http` module and `callback` is
|
||||
a function taking two arguments: `err` (JavaScript `Error` object or `null`) and
|
||||
`data` (string result).
|
||||
|
||||
### Using [webpack](https://webpack.github.io/)
|
||||
|
||||
It just works, simply require this module:
|
||||
|
||||
```js
|
||||
const CDP = require('chrome-remote-interface');
|
||||
```
|
||||
|
||||
### Using *vanilla* JavaScript
|
||||
|
||||
To generate a JavaScript file that can be used with a `<script>` element:
|
||||
|
||||
1. run `npm install` from the root directory;
|
||||
|
||||
2. manually run webpack with:
|
||||
|
||||
TARGET=var npm run webpack
|
||||
|
||||
3. use as:
|
||||
|
||||
```html
|
||||
<script>
|
||||
function criRequest(options, callback) { /*...*/ }
|
||||
</script>
|
||||
<script src="chrome-remote-interface.js"></script>
|
||||
```
|
||||
|
||||
## TypeScript Support
|
||||
|
||||
[TypeScript][] definitions are kindly provided by [Khairul Azhar Kasmiran][] and [Seth Westphal][], and can be installed from [DefinitelyTyped][]:
|
||||
|
||||
```
|
||||
npm install --save-dev @types/chrome-remote-interface
|
||||
```
|
||||
|
||||
Note that the TypeScript definitions are automatically generated from the npm package `devtools-protocol@0.0.927104`. For other versions of devtools-protocol:
|
||||
|
||||
1. Install patch-package using [the instructions given](https://github.com/ds300/patch-package#set-up).
|
||||
2. Copy the contents of the corresponding https://github.com/ChromeDevTools/devtools-protocol/tree/master/types folder (according to commit) into `node_modules/devtools-protocol/types`.
|
||||
3. Run `npx patch-package devtools-protocol` so that the changes persist across an `npm install`.

## API
|
||||
|
||||
The API consists of three parts:
|
||||
|
||||
- *DevTools* methods (for those [implementations](#implementations) that support
|
||||
them, e.g., [List](#cdplistoptions-callback), [New](#cdpnewoptions-callback),
|
||||
etc.);
|
||||
|
||||
- [connection](#cdpoptions-callback) establishment;
|
||||
|
||||
- the actual [protocol interaction](#class-cdp).
|
||||
|
||||
### CDP([options], [callback])
|
||||
|
||||
Connects to a remote instance using the [Chrome Debugging Protocol].
|
||||
|
||||
`options` is an object with the following optional properties:
|
||||
|
||||
- `host`: HTTP frontend host. Defaults to `localhost`;
|
||||
- `port`: HTTP frontend port. Defaults to `9222`;
|
||||
- `secure`: HTTPS/WSS frontend. Defaults to `false`;
|
||||
- `useHostName`: do not perform a DNS lookup of the host. Defaults to `false`;
|
||||
- `alterPath`: a `function` taking and returning the path fragment of a URL
|
||||
before that a request happens. Defaults to the identity function;
|
||||
- `target`: determines which target this client should attach to. The behavior
|
||||
changes according to the type:
|
||||
|
||||
- a `function` that takes the array returned by the `List` method and returns
|
||||
a target or its numeric index relative to the array;
|
||||
- a target `object` like those returned by the `New` and `List` methods;
|
||||
- a `string` representing the raw WebSocket URL, in this case `host` and
|
||||
`port` are not used to fetch the target list, yet they are used to complete
|
||||
the URL if relative;
|
||||
- a `string` representing the target id.
|
||||
|
||||
Defaults to a function which returns the first available target according to
|
||||
the implementation (note that at most one connection can be established to the
|
||||
same target);
|
||||
- `protocol`: [Chrome Debugging Protocol] descriptor object. Defaults to use the
|
||||
protocol chosen according to the `local` option;
|
||||
- `local`: a boolean indicating whether the protocol must be fetched *remotely*
|
||||
or if the local version must be used. It has no effect if the `protocol`
|
||||
option is set. Defaults to `false`.
|
||||
|
||||
These options are also valid properties of all the instances of the `CDP`
|
||||
class. In addition to that, the `webSocketUrl` field contains the currently used
|
||||
WebSocket URL.
|
||||
|
||||
`callback` is a listener automatically added to the `connect` event of the
|
||||
returned `EventEmitter`. When `callback` is omitted a `Promise` object is
|
||||
returned which becomes fulfilled if the `connect` event is triggered and
|
||||
rejected if the `error` event is triggered.
|
||||
|
||||
The `EventEmitter` supports the following events:
|
||||
|
||||
#### Event: 'connect'
|
||||
|
||||
```js
|
||||
function (client) {}
|
||||
```
|
||||
|
||||
Emitted when the connection to the WebSocket is established.
|
||||
|
||||
`client` is an instance of the `CDP` class.
|
||||
|
||||
#### Event: 'error'
|
||||
|
||||
```js
|
||||
function (err) {}
|
||||
```
|
||||
|
||||
Emitted when `http://host:port/json` cannot be reached or if it is not possible
|
||||
to connect to the WebSocket.
|
||||
|
||||
`err` is an instance of `Error`.
|
||||
|
||||
### CDP.Protocol([options], [callback])
|
||||
|
||||
Fetch the [Chrome Debugging Protocol] descriptor.
|
||||
|
||||
`options` is an object with the following optional properties:

|
||||
- `secure`: HTTPS/WSS frontend. Defaults to `false`;
|
||||
- `useHostName`: do not perform a DNS lookup of the host. Defaults to `false`;
|
||||
- `alterPath`: a `function` taking and returning the path fragment of a URL
|
||||
before that a request happens. Defaults to the identity function;
|
||||
- `local`: a boolean indicating whether the protocol must be fetched *remotely*
|
||||
or if the local version must be returned. Defaults to `false`.
|
||||
|
||||
`callback` is executed when the protocol is fetched, it gets the following
|
||||
arguments:
|
||||
|
||||
- `err`: a `Error` object indicating the success status;
|
||||
- `protocol`: the [Chrome Debugging Protocol] descriptor.

||||
|
||||
When `callback` is omitted a `Promise` object is returned.
|
||||
|
||||
For example:
|
||||
|
||||
```js
|
||||
const CDP = require('chrome-remote-interface');
|
||||
CDP.Protocol((err, protocol) => {
|
||||
if (!err) {
|
||||
console.log(JSON.stringify(protocol, null, 4));
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### CDP.List([options], [callback])

|
||||
- `secure`: HTTPS/WSS frontend. Defaults to `false`;
|
||||

|
||||
- `alterPath`: a `function` taking and returning the path fragment of a URL
|
||||
before that a request happens. Defaults to the identity function.
|
||||
|
||||
`callback` is executed when the list is correctly received, it gets the
|
||||
following arguments:
|
||||
|
||||
- `err`: a `Error` object indicating the success status;
|
||||
- `targets`: the array returned by `http://host:port/json/list` containing the
|
||||
target list.
|
||||
|
||||
When `callback` is omitted a `Promise` object is returned.
|
||||
|
||||
For example:
|
||||
|
||||
```js
|
||||
const CDP = require('chrome-remote-interface');
|
||||
CDP.List((err, targets) => {
|
||||
if (!err) {
|
||||
console.log(targets);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### CDP.New([options], [callback])

|
||||
before that a request happens. Defaults to the identity function;
|
||||
- `url`: URL to load in the new target/tab. Defaults to `about:blank`.
|
||||
|
||||
`callback` is executed when the target is created, it gets the following
|
||||
arguments:
|
||||
|
||||
- `err`: a `Error` object indicating the success status;
|
||||
- `target`: the object returned by `http://host:port/json/new` containing the
|
||||

|
||||
|
||||
For example:
|
||||
|
||||

|
||||
if (!err) {
|
||||
console.log(target);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### CDP.Activate([options], [callback])
|
||||
|
||||
Activate an open target/tab of the remote instance.
|
||||
|
||||
`options` is an object with the following properties:
|
||||
|
||||
- `host`: HTTP frontend host. Defaults to `localhost`;
|
||||
- `port`: HTTP frontend port. Defaults to `9222`;
|
||||

|
||||
before that a request happens. Defaults to the identity function;
|
||||
- `id`: Target id. Required, no default.
|
||||
|
||||
`callback` is executed when the response to the activation request is
|
||||
received. It gets the following arguments:
|
||||
|
||||
- `err`: a `Error` object indicating the success status;
|
||||
|
||||
When `callback` is omitted a `Promise` object is returned.
|
||||
|
||||
For example:
|
||||
|
||||
```js
|
||||
const CDP = require('chrome-remote-interface');
|
||||
CDP.Activate({id: 'CC46FBFA-3BDA-493B-B2E4-2BE6EB0D97EC'}, (err) => {
|
||||
if (!err) {
|
||||
console.log('target is activated');
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### CDP.Close([options], [callback])
|
||||
|
||||
Close an open target/tab of the remote instance.
|
||||
|
||||
`options` is an object with the following properties:

|
||||
}
|
||||
});
|
||||
```

|
||||
- `alterPath`: a `function` taking and returning the path fragment of a URL
|
||||
before that a request happens. Defaults to the identity function.
|
||||
|
||||
`callback` is executed when the version information is correctly received, it
|
||||
gets the following arguments:
|
||||
|
||||
- `err`: a `Error` object indicating the success status;
|
||||
- `info`: a JSON object returned by `http://host:port/json/version` containing
|
||||
the version information.
|
||||
|
||||
When `callback` is omitted a `Promise` object is returned.
|
||||
|
||||
For example:
|
||||
|
||||
```js
|
||||
const CDP = require('chrome-remote-interface');
|
||||
CDP.Version((err, info) => {
|
||||
if (!err) {
|
||||
console.log(info);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
### Class: CDP
|
||||
|
||||
#### Event: 'event'
|
||||
|
||||
```js
|
||||
function (message) {}
|
||||
```
|
||||
|
||||
Emitted when the remote instance sends any notification through the WebSocket.
|
||||
|
||||
`message` is the object received, it has the following properties:
|
||||
|
||||
- `method`: a string describing the notification (e.g.,
|
||||
`'Network.requestWillBeSent'`);
|
||||
- `params`: an object containing the payload;
|
||||
- `sessionId`: an optional string representing the session identifier.
|
||||
|
||||
Refer to the [Chrome Debugging Protocol] specification for more information.
|
||||
|
||||
For example:
|
||||
|
||||
```js
|
||||
client.on('event', (message) => {
|
||||
if (message.method === 'Network.requestWillBeSent') {
|
||||
console.log(message.params);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
#### Event: '`<domain>`.`<method>`'
|
||||
|
||||
```js
|
||||
function (params, sessionId) {}
|
||||
```
|
||||
|
||||
Emitted when the remote instance sends a notification for `<domain>.<method>`
|
||||
through the WebSocket.
|
||||
|
||||
`params` is an object containing the payload.
|
||||
|
||||
`sessionId` is an optional string representing the session identifier.
|
||||
|
||||
This is just a utility event which allows to easily listen for specific
|
||||
notifications (see [`'event'`](#event-event)), for example:
|
||||
|
||||
```js
|
||||
client.on('Network.requestWillBeSent', console.log);
|
||||
```
|
||||
|
||||
Additionally, the equivalent `<domain>.on('<method>', ...)` syntax is available, for example:
|
||||
|
||||
```js
|
||||
client.Network.on('requestWillBeSent', console.log);
|
||||
```
|
||||
|
||||
#### Event: '`<domain>`.`<method>`.`<sessionId>`'
|
||||
|
||||
```js
|
||||
function (params, sessionId) {}
|
||||
```
|
||||
|
||||
Equivalent to the following but only for those events belonging to the given `session`:
|
||||
|
||||
```js
|
||||
client.on('<domain>.<event>', callback);
|
||||
```
|
||||
|
||||
#### Event: 'ready'
|
||||
|
||||
```js
|
||||
function () {}
|
||||
```
|
||||
|
||||
Emitted every time that there are no more pending commands waiting for a
|
||||
response from the remote instance. The interaction is asynchronous so the only
|
||||
way to serialize a sequence of commands is to use the callback provided by
|
||||
the [`send`](#clientsendmethod-params-callback) method. This event acts as a
|
||||
barrier and it is useful to avoid the *callback hell* in certain simple
|
||||
situations.
|
||||
|
||||
Users are encouraged to extensively check the response of each method and should
|
||||
prefer the promises API when dealing with complex asynchronous program flows.
|
||||
|
||||
For example to load a URL only after having enabled the notifications of both
|
||||
`Network` and `Page` domains:
|
||||
|
||||
```js
|
||||
client.Network.enable();
|
||||
client.Page.enable();
|
||||
client.once('ready', () => {
|
||||
client.Page.navigate({url: 'https://github.com'});
|
||||
});
|
||||
```
|
||||
|
||||
In this particular case, not enforcing this kind of serialization may cause that
|
||||
the remote instance does not properly deliver the desired notifications the
|
||||
client.
|
||||
|
||||
|
||||
#### Event: 'disconnect'
|
||||
|
||||
```js
|
||||
function () {}
|
||||
```
|
||||
|
||||
Emitted when the instance closes the WebSocket connection.
|
||||
|
||||
This may happen for example when the user opens DevTools or when the tab is
|
||||
closed.
|
||||
|
||||
#### client.send(method, [params], [sessionId], [callback])
|
||||
|
||||
Issue a command to the remote instance.
|
||||
|
||||
`method` is a string describing the command.
|
||||
|
||||
`params` is an object containing the payload.
|
||||
|
||||
`sessionId` is a string representing the session identifier.
|
||||
|
||||
`callback` is executed when the remote instance sends a response to this
|
||||
command, it gets the following arguments:
|
||||
|
||||
- `error`: a boolean value indicating the success status, as reported by the
|
||||
remote instance;
|
||||
- `response`: an object containing either the response (`result` field, if
|
||||
`error === false`) or the indication of the error (`error` field, if `error
|
||||
=== true`).
|
||||
|
||||
When `callback` is omitted a `Promise` object is returned instead, with the
|
||||
fulfilled/rejected states implemented according to the `error` parameter. The
|
||||
`Error` object con be an instance of [`ProtocolError`](#cdpprotocolerror) for
|
||||
protocol invocation errors. Alternatively, in case of low-level WebSocket
|
||||
errors, the `error` parameter contains the originating `Error` object.
|
||||
|
||||
Note that the field `id` mentioned in the [Chrome Debugging Protocol]
|
||||
specification is managed internally and it is not exposed to the user.
|
||||
|
||||
For example:
|
||||
|
||||
```js
|
||||
client.send('Page.navigate', {url: 'https://github.com'}, console.log);
|
||||
```
|
||||
|
||||
#### client.`<domain>`.`<method>`([params], [sessionId], [callback])
|
||||
|
||||
Just a shorthand for:
|
||||
|
||||
```js
|
||||
client.send('<domain>.<method>', params, sessionId, callback);
|
||||
```
|
||||
|
||||
For example:
|
||||
|
||||
```js
|
||||
client.Page.navigate({url: 'https://github.com'}, console.log);
|
||||
```
|
||||
|
||||
#### client.`<domain>`.`<event>`([sessionId], [callback])
|
||||
|
||||
Just a shorthand for:
|
||||
|
||||
```js
|
||||
client.on('<domain>.<event>[.<sessionId>]', callback);
|
||||
```
|
||||
|
||||
When `callback` is omitted the event is registered only once and a `Promise`
|
||||
object is returned. Notice though that in this case the optional `sessionId` usually passed to `callback` is not returned.
|
||||
|
||||
When `callback` is provided, it returns a function that can be used to
|
||||
unsubscribe `callback` from the event, it can be useful when anonymous functions
|
||||
are used as callbacks.
|
||||
|
||||
For example:
|
||||
|
||||
```js
|
||||
const unsubscribe = client.Network.requestWillBeSent((params, sessionId) => {
|
||||
console.log(params.request.url);
|
||||
});
|
||||
unsubscribe();
|
||||
```
|
||||
|
||||
#### client.close([callback])
|
||||
|
||||
Close the connection to the remote instance.
|
||||
|
||||
`callback` is executed when the WebSocket is successfully closed.
|
||||
|
||||
When `callback` is omitted a `Promise` object is returned.
|
||||
|
||||
#### client['`<domain>`.`<name>`']
|
||||
|
||||
Just a shorthand for:
|
||||
|
||||
```js
|
||||
client.<domain>.<name>
|
||||
```
|
||||
|
||||
Where `<name>` can be a command, an event, or a type.
|
||||
|
||||
### CDP.ProtocolError
|
||||
|
||||
Error returned by the [`send`](#clientsendmethod-params-callback) method in case Chrome experienced issues in the protocol invocation. It exposes the following fields:
|
||||
|
||||
- `request`: the raw request object containing the `method`, `params`, and `sessionId` fields;
|
||||
- `response`: the raw response from Chrome, usually containing the `code`, `message`, and `data` fields.
|
||||
|
||||
## FAQ
|
||||
|
||||
### Invoking `Domain.methodOrEvent` I obtain `Domain.methodOrEvent is not a function`
|
||||
|
||||
This means that you are trying to use a method or an event that are not present
|
||||
in the protocol descriptor that you are using.
|
||||
|
||||
If the protocol is fetched from Chrome directly, then it means that this version
|
||||
of Chrome does not support that feature. The solution is to update it.
|
||||
|
||||
If you are using a local or custom version of the protocol, then it means that
|
||||
the version is obsolete. The solution is to provide an up-to-date one, or if you
|
||||
are using the protocol embedded in chrome-remote-interface, make sure to be
|
||||
running the latest version of this module. In case the embedded protocol is
|
||||
obsolete, please [file an issue](https://github.com/cyrus-and/chrome-remote-interface/issues/new).
|
||||
|
||||
See [here](#chrome-debugging-protocol-versions) for more information.
|
||||
|
||||
### Invoking `Domain.method` I obtain `Domain.method wasn't found`
|
||||
|
||||
This means that you are providing a custom or local protocol descriptor
|
||||
(`CDP({protocol: customProtocol})`) which declares `Domain.method` while the
|
||||
Chrome version that you are using does not support it.
|
||||
|
||||
To inspect the currently available protocol descriptor use:
|
||||
|
||||
```
|
||||
$ chrome-remote-interface inspect
|
||||
```
|
||||
|
||||
See [here](#chrome-debugging-protocol-versions) for more information.
|
||||
|
||||
### Why my program stalls or behave unexpectedly if I run Chrome in a Docker container?
|
||||
|
||||
This happens because the size of `/dev/shm` is set to 64MB by default in Docker
|
||||
and may not be enough for Chrome to navigate certain web pages.
|
||||
|
||||
You can change this value by running your container with, say,
|
||||
`--shm-size=256m`.
|
||||
|
||||
### Using `Runtime.evaluate` with `awaitPromise: true` I sometimes obtain `Error: Promise was collected`
|
||||
|
||||
This is thrown by `Runtime.evaluate` when the browser-side promise gets
|
||||
*collected* by the Chrome's garbage collector, this happens when the whole
|
||||
JavaScript execution environment is invalidated, e.g., a when page is navigated
|
||||
or reloaded while a promise is still waiting to be resolved.
|
||||
|
||||
Here is an example:
|
||||
|
||||
```
|
||||
$ chrome-remote-interface inspect
|
||||
>>> Runtime.evaluate({expression: `new Promise(() => {})`, awaitPromise: true})
|
||||
>>> Page.reload() // then wait several seconds
|
||||
{ result: {} }
|
||||
{ error: { code: -32000, message: 'Promise was collected' } }
|
||||
```
|
||||
|
||||
To fix this, just make sure there are no pending promises before closing,
|
||||
reloading, etc. a page.
|
||||
|
||||
### How does this compare to Puppeteer?
|
||||
|
||||
[Puppeteer] is an additional high-level API built upon the [Chrome Debugging
|
||||
Protocol] which, among the other things, may start and use a bundled version of
|
||||
Chromium instead of the one installed on your system. Use it if its API meets
|
||||
your needs as it would probably be easier to work with.
|
||||
|
||||
chrome-remote-interface instead is just a general purpose 1:1 Node.js binding
|
||||
for the [Chrome Debugging Protocol]. Use it if you need all the power of the raw
|
||||
protocol, e.g., to implement your own high-level API.
|
||||
|
||||
See [#240] for a more thorough discussion.
