React Chrome Extension

A chrome extension boilerplate project with ReactJs using inject page strategy.

Stop worrying about the configurational challenges of setting up the Chrome extension, just start writing your components as usual. Read detailed blog

This project is sponsored By Recast Studio

The boilerplate is to quickly create a chrome extension using ReactJs, The motivation behind creating a boilerplate was:

1. Instead of Chrome's ready-made popup, We wanted our page injected into DOM as a sidebar for better UX.

2. We wanted to use ReactJs for the Component-based approach, Routing, and its build mechanism.

3. We need to make sure that the extension CSS does not conflict with the host page styles in any case.

Features

• Used ReactJs to write Chrome extension
• Injecting extension to host page as a content script
• Utilized the Chrome messaging API
• Isolated extension CSS using Iframe

Installation

Make sure you have NodeJs(>18) version installed

Clone repo

git clone https://github.com/satendra02/react-chrome-extension.git

Go to the react-chrome-extension directory and run

yarn install

Now build the extension using

yarn build

You will see a build folder generated inside [PROJECT_HOME]

To avoid running yarn build after updating any file, you can run

yarn watch

which listens to any local file changes, and rebuilds automatically.

Adding React app extension to Chrome

In the Chrome browser, go to chrome://extensions page and switch on developer mode. This enables the ability to locally install a Chrome extension.

Now click on the LOAD UNPACKED and browse to [PROJECT_HOME]\build, This will install the React app as a Chrome extension.

When you go to any website and click on the extension icon, the injected page will toggle.

Using SASS

Boilerplate contains sass-loader, so you can use SASS instead of pure CSS in your project. To do so:

1. Rename src/App.css file to src/App.scss
2. Change import line in src/app.js from import './App.css'; to import './App.scss';
