Vue DevTools for Rspack & Rsbuild

Vue DevTools v9 - the floating dock, component tree with live state editing, in-page component picker, timeline, router & pinia inspectors and open-in-editor - for projects built with Rspack and Rsbuild.

Upstream ships Vue DevTools as vite-plugin-vue-devtools, leaving Rspack users with only the browser extension. This project closes that gap with feature parity against vite-plugin-vue-devtools@9.0.0-beta.0 - without rewriting DevTools. Under Vite, v9 lives inside Vite DevTools; here the same devframe hub that Vite DevTools is built on is mounted on your Rspack/Rsbuild dev server. See docs/COMPATIBILITY.md.

Requirements

Node 20.19+ or 22.12+. These packages are ESM only - no CommonJS build is shipped. A CommonJS config (rspack.config.js with require()) still works on those versions thanks to Node's require(esm) support.

Quick start

Rsbuild

pnpm add -D @vue-devtools-rstack/rsbuild

// rsbuild.config.ts
import { defineConfig } from '@rsbuild/core'
import { pluginVue } from '@rsbuild/plugin-vue'
import { pluginVueDevTools } from '@vue-devtools-rstack/rsbuild'

export default defineConfig({
  plugins: [pluginVue(), pluginVueDevTools()],
})

Start the dev server - the DevTools dock appears in the corner of your app, and the standalone viewer is reachable at http://localhost:<port>/__devtools/.

Raw Rspack

pnpm add -D @vue-devtools-rstack/rspack

// rspack.config.mjs
import { VueDevToolsRspackPlugin } from '@vue-devtools-rstack/rspack'
import { createDevtoolsMiddlewares, printDevtoolsBanner } from '@vue-devtools-rstack/rspack/middleware'

const devtoolsServer = createDevtoolsMiddlewares()

export default {
  plugins: [/* VueLoaderPlugin, HtmlRspackPlugin, ... */ new VueDevToolsRspackPlugin()],
  devServer: {
    onListening: () => printDevtoolsBanner(3000),
    setupMiddlewares: (middlewares, devServer) => {
      devtoolsServer.attach(devServer.server)
      middlewares.unshift(...devtoolsServer.middlewares)
      return middlewares
    },
  },
}

Options

Option	Type	Default	Description
enabled	boolean	true	Install Vue DevTools and register its dock entry.
appendTo	string | RegExp | Array<string | RegExp>	-	Import the devtools from matching modules instead of injecting a <script> tag (for apps without an HTML entry).
launchEditor	string	process.env.LAUNCH_EDITOR, else auto-detected	Editor opened by open-in-editor.
embeddedVisibility	'normal' | 'passive' | 'hidden'	'normal'	Initial visibility of the floating dock.
dockPreferences	object	-	Dock bar preferences (category order, first-run position).
allowedOrigins	string[]	[]	Origins allowed on the DevTools socket besides loopback - for LAN or tunnel access.

@vue-devtools-rstack/rspack additionally accepts base (dev-server base path), and its createDevtoolsMiddlewares accepts root.

Migrating from 0.1.x (Vue DevTools v8)

• The v8 overlay is replaced by the devframe dock. /__devtools__/ still serves the client SPA, but it only connects to the app from inside the dock; open /__devtools/ for a separate window.
• componentInspector is removed: the component picker is built into v9 (the crosshair button in the components tab). Passing the option logs a warning.
• The assets, module graph and Vite Inspect tabs are gone upstream, and so are the rspack stats collector and assets watcher: VueDevToolsRspackPlugin#collector and the publicDir, distPath and collector options of createDevtoolsMiddlewares were removed.

Development

pnpm install
pnpm build          # build all packages (rslib) - run this first
pnpm lint           # rslint, lint + type check in one pass
pnpm typecheck      # rslint, types only
pnpm dev            # rsbuild playground on :3333
pnpm --filter playground-rspack-app dev   # raw rspack playground on :3344
pnpm e2e            # full Playwright suite (all four legs)
pnpm check:publish  # publint + attw over the packed tarballs

The toolchain is Rstack throughout: packages are built with Rslib, linted with Rslint, and exercised against both Rsbuild and raw Rspack playgrounds.

Linting is type-aware and covers the packages, the e2e specs and the playgrounds, so it needs the packages built first - cross-package imports resolve through the declarations in dist/.
