download-chromium

Download Chromium!

Caches executables locally so you never download them twice.

Comes with a convenient CLI, so you can do things like this:

$ $(download-chromium) --headless --screenshot --disable-gpu https://twitter.com/

Usage

Use the CLI:

$ download-chromium
Downloading Chromium r499413...Done!
/Users/julian/.chromium-cache/chromium-mac-499413/chrome-mac/Chromium.app/Contents/MacOS/Chromium

Or use the JavaScript API:

const download = require('download-chromium')

const exec = await download()
console.log(`Downloaded Chromium to ${exec}`)

$ node example.js
Downloaded Chromium to /Users/julian/.chromium-cache/chromium-mac-499413/chrome-mac/Chromium.app/Contents/MacOS/Chromium

Installation

# for the CLI

$ npm install -g download-chromium

# for the API

$ npm install download-chromium

API

download

download({ 
	platform = currentPlatform, 
	revision = '499413', 
	log = false, 
	onProgress = undefined, 
	installPath = '{__dirname}/.local-chromium' })

Returns a Promise resolving with the Chromium executable path.

• installPath: set the install path if you can't write to your node_modules, eg from within an electron packaged app (installPath: require('electron').app.getPath('userData'))
• onProgress: track download progress. onProgress receives one argument { percent, transferred, total }
