Intro

This boilerplate is meant to be a quick start for creating chrome extensions using React, Typescript and Tailwind CSS.

Built for:

For improved DX and rapid building vite and nodemon are used.

Chrome does not accept manifest v2 extensions since Jan 2022, therefore this template uses manifest v3.

Firefox + other browsers don't yet support manifest v3, so cross browser usage is not encouraged.

• Read more about Chrome manifest v2 support here.
• Read more about Firefox Manifest v3 support here.

As soon as Firefox supports manifest v3, support will be added in this repo as well.

Oh by the way ... I also implemented a chrome local/sync storage hook for react, which works well with this template. Check it out here.

Why another boilerplate?

I have used webpack react boilerplates and found it too hard to configure.

Vite is actually mega easy to understand, which makes it easier to get into and to maintain for others.

I couldn't find a boilerplate for React, TypeScript and Tailwind CSS. So here it is.

Features

• React 18
• TypeScript
• Vite
• Tailwind CSS
• ESLint
• Chrome Extension Manifest Version 3

Usage

Setup

1. Clone this repository.
2. Change name and description in package.json => Auto synchronize with manifest
3. Run yarn or npm i (check your node version >= 16)
4. Run yarn dev or npm run dev
5. Load Extension on Chrome
   1. Open - Chrome browser
   2. Access - chrome://extensions
   3. Check - Developer mode
   4. Find - Load unpacked extension
   5. Select - dist folder in this project (after dev or build)
6. If you want to build in production, Just run yarn build or npm run build.

Customization

As the template has all of the potential Chrome extension pages implemented, you likely have to customize it to fit your needs.

E.g. you don't want the newtab page to activate whenever you open a new tab:

1. remove the directory newtab and its contents in src/pages
2. remove the newtab rollup input in the vite.config.ts

//...
build: {
    outDir,
    rollupOptions: {
      input: {
        devtools: resolve(pagesDir, 'devtools', 'index.html'),
        panel: resolve(pagesDir, 'panel', 'index.html'),
        content: resolve(pagesDir, 'content', 'index.ts'),
        background: resolve(pagesDir, 'background', 'index.ts'),
        popup: resolve(pagesDir, 'popup', 'index.html'),
        newtab: resolve(pagesDir, 'newtab', 'index.html'),  // <--- REMOVE THIS LINE
        options: resolve(pagesDir, 'options', 'index.html'),
      },
      output: {
        entryFileNames: (chunk) => `src/pages/${chunk.name}/index.js`,
      },
    },
  },
/...

CSS files in the src/pages/* directories are not necessary. They are left in there in case you want to use it in combination with Tailwind CSS. Feel free to delete them.

Tailwind can be configured as usual in the tailwind.config.cjs file. See doc link below.

Heavily inspired by Jonghakseo's vite chrome extension boilerplate. It uses SASS instead of TailwindCSS if you want to check it out.
