## What it is
A TypeScript + React starter template for building cross-browser web extensions with a single codebase targeting Chrome, Firefox, Edge, and Opera. It uses Vite for fast builds, generates browser-tailored Manifest V3 files, and includes SASS with CSS Modules and ESLint/Prettier tooling.

## Use cases
- build a chrome extension with react and typescript
- write once run on any browser web extension
- starter template for manifest v3 extension
- cross-browser firefox and chrome addon boilerplate
- set up vite build for browser extension
- scaffold a web extension project with hot reload

## When to choose
- starting a new browser extension from scratch
- you need one codebase targeting multiple browsers
- you want a modern Vite + React + TypeScript extension setup

## When to avoid
- you need Manifest V2 support for legacy browsers
- you prefer a framework other than React
- you are extending an existing extension with its own build setup
