electron-chrome-web-store

Install and update Chrome extensions from the Chrome Web Store for Electron.

Usage

npm install electron-chrome-web-store

[!TIP] To enable full support for Chrome extensions in Electron, install electron-chrome-extensions.

Enable downloading extensions from the Chrome Web Store

const { app, BrowserWindow, session } = require('electron')
const { installChromeWebStore } = require('electron-chrome-web-store')

app.whenReady().then(async () => {
  const browserSession = session.defaultSession
  const browserWindow = new BrowserWindow({
    webPreferences: {
      session: browserSession,
    },
  })

  // Install Chrome web store and wait for extensions to load
  await installChromeWebStore({ session: browserSession })

  browserWindow.loadURL('https://chromewebstore.google.com/')
})

Install and update extensions programmatically

const { app, session } = require('electron')
const { installExtension, updateExtensions } = require('electron-chrome-web-store')

app.whenReady().then(async () => {
  // Install Dark Reader
  await installExtension('eimadpbcbfnmbkopoojfekhnkhdbieeh')

  // Install React Developer Tools with file:// access
  await installExtension('fmkadmapgofadopljbjfkapdkoienihi', {
    loadExtensionOptions: { allowFileAccess: true },
  })

  // Install uBlock Origin Lite to custom session
  await installExtension('ddkjiahejlhfcafbddmgiahcphecmpfh', {
    session: session.fromPartition('persist:browser'),
  })

  // Check and install updates for all loaded extensions
  await updateExtensions()
})

Packaging the preload script

This module uses a preload script. When packaging your application, it's required that the preload script is included. This can be handled in two ways:

1. Include node_modules in your packaged app. This allows electron-chrome-web-store/preload to be resolved.
2. In the case of using JavaScript bundlers, you may need to copy the preload script next to your app's entry point script. You can try using copy-webpack-plugin, vite-plugin-static-copy, or rollup-plugin-copy depending on your app's configuration.

Here's an example for webpack configurations:

module.exports = {
  entry: './index.js',
  plugins: [
    new CopyWebpackPlugin({
      patterns: [require.resolve('electron-chrome-web-store/preload')],
    }),
  ],
}
