CRXJS Chrome extension development — true HMR for popup, options, content scripts, side panels, manifest-driven builds, dynamic content script imports (`?script`, `?script&module`), and `defineManifest` for type-safe manifests. Uses Vite as its build tool. Use when the user mentions CRXJS, crxjs, @crxjs/vite-plugin, 'extension with hot reload', 'HMR for chrome extension', or wants to set up a CRXJS-based Chrome extension project with any framework (React, Vue, Svelte, Solid, Vanilla). Also…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CRXJS
CRXJS is a Chrome extension development tool that provides true HMR for popup, options, content scripts, and side panels. It reads your manifest to auto-generate the extension output, handles content script injection, and manages the service worker build. Under the hood it is a Vite plugin (`@crxjs/vite-plugin`).
## Current status
- **Package**: `@crxjs/vite-plugin` (v2.x stable, latest v2.4.0 as of March 2026)
- **Scaffolding**: `npm create crxjs@latest` (always use `@latest`)
- **Maintained by**: @Toumash and @FliPPeDround (since mid-2025)
- **GitHub**: github.com/crxjs/chrome-extension-tools (~4k stars)
- **Vite compatibility**: v3 through v8-beta
## Quick start
```bash
# Scaffold new project (picks framework interactively)
npm create crxjs@latest
# Or add to existing Vite project
npm install @crxjs/vite-plugin -D
```
## Vite config by framework
CRXJS is added as a Vite plugin. The setup varies slightly per framework.
### React
```typescript
// vite.config.ts
import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import { crx } from "@crxjs/vite-plugin";
import manifest from "./manifest.json";
export default defineConfig({

How to install
mdr add samber/cc-skills/crxjs@sha256:0c55dd601dbea413The line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
