개요

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 trigger when the user has an existing CRXJS project and wants to add features, fix HMR issues, or configure content scripts with CRXJS. For general Chrome extension architecture (messaging, CSP, storage, permissions) -> See `samber/cc-skills@chrome-extension` skill.

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

# 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

// 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({
  plugins: [react(), crx({ manifest })],
});

Use @vitejs/plugin-react (not plugin-react-swc) for best HMR compatibility. If you must use SWC, cast the manifest:

import { ManifestV3Export } from "@crxjs/vite-plugin";
const manifest = manifestJson as ManifestV3Export;

Vue

import vue from "@vitejs/plugin-vue";
import { crx } from "@crxjs/vite-plugin";
import manifest from "./manifest.json";

export default defineConfig({
  plugins: [vue(), crx({ manifest })],
});

Svelte

import { svelte } from "@sveltejs/vite-plugin-svelte";
import { crx } from "@crxjs/vite-plugin";
import manifest from "./manifest.json";

export default defineConfig({
  plugins: [svelte(), crx({ manifest })],
});

Vanilla TypeScript

import { crx } from "@crxjs/vite-plugin";
import manifest from "./manifest.json";

export default defineConfig({
  plugins: [crx({ manifest })],
});

defineManifest — type-safe dynamic manifest

Instead of a static JSON file, use CRXJS's defineManifest for dynamic values and full TypeScript autocompletion:

// manifest.ts
import { defineManifest } from "@crxjs/vite-plugin";
import pkg from "./package.json";

export default defineManifest((config) => ({
  manifest_version: 3,
  name: config.command === "serve" ? `[DEV] ${pkg.name}` : pkg.name,
  version: pkg.version,
  description: pkg.description,
  permissions: ["storage", "activeTab", "scripting"],
  action: {
    default_popup: "src/popup/index.html",
    default_icon: {
      "16": "public/icons/icon16.png",
      "48": "public/icons/icon48.png",
    },
  },
  background: {
    service_worker: "src/background/index.ts",
    type: "module",
  },
  content_scripts: [
    {
      matches: ["https://*/*"],
      js: ["src/content/index.ts"],
      css: ["src/content/styles.css"],
    },
  ],
  options_page: "src/options/index.html",
  side_panel: { default_path: "src/sidepanel/index.html" },
  icons: {
    "16": "public/icons/icon16.png",
    "48": "public/icons/icon48.png",
    "128": "public/icons/icon128.png",
  },
}));

Import in vite.config.ts:

import manifest from "./manifest";
// ... crx({ manifest })

Type declarations

Add to a src/vite-env.d.ts or src/crxjs.d.ts:

/// <reference types="@crxjs/vite-plugin/client" />

This enables types for ?script and ?script&module imports.

HMR behavior by context

Context	HMR	How it works
Popup	Full HMR	WebSocket-based, state preserved
Options page	Full HMR	Same as popup
Side panel	Full HMR	Same as popup
Content script (manifest)	True HMR	CRXJS injects loader + HMR client
Content script (dynamic)	True HMR	Via `?script` import
Service worker	Auto-reload	Changes trigger full extension reload
Main world scripts	No HMR	Skipped by CRXJS loader

Content script HMR works because CRXJS generates a loader script that imports an HMR preamble, the HMR client, and your actual script — enabling real module-level HMR without full page reload. This is CRXJS's main differentiator.

Dynamic content script imports

For content scripts injected programmatically (not in manifest), CRXJS provides special import suffixes:

// background.ts — ?script gives you a resolved path for executeScript
import contentScript from "./content?script";

chrome.action.onClicked.addListener(async (tab) => {
  await chrome.scripting.executeScript({
    target: { tabId: tab.id! },
    files: [contentScript],
  });
});

For main world injection (no HMR):

import mainWorldScript from "./inject?script&module";

await chrome.scripting.executeScript({
  target: { tabId },
  world: "MAIN",
  files: [mainWorldScript],
});

CRXJS plugin options

crx({
  manifest,
  browser: "chrome", // 'chrome' | 'firefox'
  contentScripts: {
    injectCss: true, // auto-inject CSS for content scripts
    hmrTimeout: 5000, // HMR connection timeout (ms)
  },
});

Development workflow

# Start dev server (outputs to dist/ with HMR)
npm run dev

# 1. Open chrome://extensions
# 2. Enable "Developer mode"
# 3. Click "Load unpacked"
# 4. Select the dist/ directory
# 5. Edit code — popup/content scripts update instantly via HMR
# 6. Service worker changes trigger automatic extension reload

After loading once, subsequent npm run dev sessions reconnect automatically. No need to re-load the extension unless manifest.json changes.

Production build

npm run build    # outputs to dist/

The dist/ directory is ready to zip and upload to Chrome Web Store:

cd dist && zip -r ../extension.zip .

Disable Vite's module preload to avoid CWS rejection of inline scripts:

build: {
  modulePreload: false;
}

Known issues and workarounds

Tailwind CSS HMR in content scripts

New Tailwind classes may not trigger CSS updates in content scripts. Workaround: restart dev server after adding new utility classes. Improved in v2.4.0 but not fully resolved. Ensure injectCss: true in config.

WebSocket connection errors (`ws://localhost:undefined/`)

Cause: port mismatch between dev server and HMR config. Fix: explicitly set both to the same value:

server: {
  port: 5173,
  strictPort: true,
  hmr: { port: 5173 },
}

"Manifest version 2 is deprecated" warning

If you see this, your manifest is being interpreted as MV2. Fix: ensure "manifest_version": 3 is set.

Content scripts not injecting on file:// URLs

Chrome requires the user to enable "Allow access to file URLs" in the extension settings at chrome://extensions. CRXJS cannot change this.

HMR stops working after Chrome update

CRXJS's HMR relies on injecting a content script that connects to the dev server's WebSocket. Chrome security updates occasionally break this. Fix: update to the latest CRXJS version, which tracks Chrome changes.

CRXJS vs alternatives

Feature	CRXJS	WXT	Plasmo
Content script HMR	True HMR	File-based reload	Partial
Framework support	Any Vite framework	Any	React-focused
Abstraction level	Thin (Vite plugin)	Full framework	Full framework
Messaging helpers	None (use chrome.* directly)	Built-in	Built-in
Storage wrappers	None	Built-in	Built-in
Cross-browser	Chrome + Firefox	Chrome + Firefox + Safari	Chrome + Firefox
File-based routing	No	Yes	Yes
Learning curve	Low (know Vite, know CRXJS)	Medium	Medium

Choose CRXJS when: you want minimal abstraction over raw Chrome APIs and value content script HMR above all. CRXJS stays out of the way — no magic routing, no wrapper APIs, just your code with HMR.

Choose WXT when: you want conventions, built-in utilities, and cross-browser support.

Choose Plasmo when: you're React-focused and want the highest-level abstraction.

# 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)

import manifest from "./manifest.json";

export default defineConfig({
  plugins: [vue(), crx({ manifest })],
});
```

### Svelte

```typescript
import { svelte } from "@sveltejs/vite-plugin-svelte";
import { crx } from "@crxjs/vite-plugin";
import manifest from "./manifest.json";

export default defineConfig({
  plugins: [svelte(), crx({ manifest })],
});
```

### Vanilla TypeScript

```typescript
import { crx } from "@crxjs/vite-plugin";
import manifest from "./manifest.json";

export default defineConfig({
  plugins: [crx({ manifest })],
});
```

## defineManifest — type-safe dynamic manifest

Instead of a static JSON file, use CRXJS's `defineManifest` for dynamic values and full TypeScript autocompletion:

```typescript
// manifest.ts

  action: {
    default_popup: "src/popup/index.html",
    default_icon: {
      "16": "public/icons/icon16.png",
      "48": "public/icons/icon48.png",
    },
  },
  background: {
    service_worker: "src/background/index.ts",
    type: "module",
  },
  content_scripts: [
    {
      matches: ["https://*/*"],
      js: ["src/content/index.ts"],
      css: ["src/content/styles.css"],
    },
  ],
  options_page: "src/options/index.html",
  side_panel: { default_path: "src/sidepanel/index.html" },
  icons: {
    "16": "public/icons/icon16.png",
    "48": "public/icons/icon48.png",
    "128": "public/icons/icon128.png",
  },
}));
```

Import in vite.config.ts:

```typescript
import manifest from "./manifest";
// ... crx({ manifest })
```

## Type declarations

Add to a `src/vite-env.d.ts` or `src/crxjs.d.ts`:

```typescript
/// <reference types="@crxjs/vite-plugin/client" />

For main world injection (no HMR):

```typescript
import mainWorldScript from "./inject?script&module";

await chrome.scripting.executeScript({
  target: { tabId },
  world: "MAIN",
  files: [mainWorldScript],
});
```

## CRXJS plugin options

```typescript
crx({
  manifest,
  browser: "chrome", // 'chrome' | 'firefox'
  contentScripts: {
    injectCss: true, // auto-inject CSS for content scripts
    hmrTimeout: 5000, // HMR connection timeout (ms)
