## What it is
WXT is a TypeScript framework for building web browser extensions, described as 'like Nuxt, but for Web Extensions'. It provides file-based entrypoints, automatic manifest generation, HMR dev mode, multi-browser and MV2/MV3 targeting, and automated zipping and publishing.

## Use cases
- build a chrome extension with typescript
- develop browser extensions with hot reload
- build one extension codebase for chrome and firefox
- generate manifest.json from entrypoint files
- migrate a webextension from manifest v2 to v3
- automate zipping and publishing extensions to stores
- use react or vue inside a browser extension

## When to choose
- you're starting a new browser extension project in the JS/TS ecosystem
- you need to target multiple browsers or both MV2 and MV3 from one codebase
- you want fast HMR dev mode and auto-generated manifests instead of hand-written build scripts
- you want Nuxt-like DX: auto-imports, file-based entrypoints, module system

## When to avoid
- you're building extensions outside the JavaScript/TypeScript ecosystem
- you have a simple existing extension with a working build setup and no need for a framework
- you need non-browser-extension packaging like Electron or PWAs
