React Chrome Extension Boilerplate

Boilerplate for Chrome Extension React.js project.

Features

• Simple React/Redux examples of Chrome Extension Window & Popup & Inject pages
• Hot reloading React/Redux (Using Webpack and React Transform)
• Write code with ES2015+ syntax (Using Babel)
• E2E tests of Window & Popup & Inject pages (Using Chrome Driver, Selenium Webdriver)

Examples

The example is edited from Redux TodoMVC example.

Popup

The todos state will be saved to chrome.storage.local.

Window

The context menu is created by chrome/extension/background/contextMenus.js.

Inject page

The inject script is being run by chrome/extension/background/inject.js. A simple example will be inject bottom of page(https://github.com/*) if you visit.

Installation

# clone it
$ git clone https://github.com/jhen0409/react-chrome-extension-boilerplate.git

# Install dependencies
$ npm install

Development

• Run script

# build files to './dev'
# start webpack development server
$ npm run dev

• If you're developing Inject page, please allow https://localhost:3000 connections. (Because injectpage injected GitHub (https) pages, so webpack server procotol must be https.)
• Load unpacked extensions with ./dev folder.

React/Redux hot reload

This boilerplate uses Webpack and react-transform, and use Redux. You can hot reload by editing related files of Popup & Window & Inject page.

Using Redux DevTools Extension

You can use redux-devtools-extension on development mode.

$ npm run build

Compress

# compress build folder to {manifest.name}.zip and crx
$ npm run build
$ npm run compress -- [options]

Options

If you want to build crx file (auto update), please provide options, and add update.xml file url in [manifest.json](https://developer.chrome.com/extensions/autoupdate#update_url manifest.json).

• --app-id: your extension id (can be get it when you first release extension)

  you can use npm run compress-keygen to generate private key ./key.pem
