Chrome Connector

Control any Chrome using Chrome Debugging Protocol.

* Promise-based sendCommand (async/await)
* Works everywhere (browser, Node.js, Electron, etc)
* Thin on dependencies

Usage

First you need to obtain a remote debugging target.

Here's an example of how to do this manually:

``bash


Start Chrome in debugging mode

/path/to/chrome/Chrome --remote-debugging-port=9222

Obtain a webSocketDebuggerUrl

curl http://localhost:9222/json
`

This will give you an array of debugging targets like this:

`
[{
"description": "",
"devtoolsFrontendUrl": "/devtools/inspector.html?ws=localhost:9222/devtools/page/74863d10-ff7c-43d9-b847-104c3a39e43f",
"faviconUrl": "https://www.google.ru/favicon.ico",
"id": "74863d10-ff7c-43d9-b847-104c3a39e43f",
"title": "New Tab",
"type": "page",
"url": "chrome://newtab/",
"webSocketDebuggerUrl": "ws://localhost:9222/devtools/page/74863d10-ff7c-43d9-b847-104c3a39e43f"
}, ...]
`

You'll need webSocketDebuggerUrl there:

`es6
const { ChromeConnector } = require('chrome-connector');

const chrome = new ChromeConnector('ws://localhost:9222/devtools/page/74863d10-ff7c-43d9-b847-104c3a39e43f');

await chrome.connect();

// Send CDP commands
const res = await chrome.sendCommand('Page.navigate', { url: 'http://github.com' });
// Read CDP response
const { frameId } = res;

// Subscribe to CDP events
chrome.on('Page.frameStoppedLoading', params => {
// Access CDP event parameters
const { frameId } = params;
});
