DevTools for Oxc

DevTools for Oxc (@vitejs/devtools-oxc) is a built-in integration that inspects the Oxc toolchain — oxlint and oxfmt. It was donated from yuyinws/oxc-inspector by Leo.

What it does

• Visualize lint output — explore oxlint results in an interactive interface.
• Config helper — read oxlint and oxfmt configuration at a glance.

Getting started

DevTools for Oxc ships with Vite DevTools. When its package is present it mounts via DevToolsOxc(); otherwise open the Oxc launcher in the dock to install it on demand, then restart the dev server.

vite.config.ts

import { DevTools } from '@vitejs/devtools'
import { DevToolsOxc } from '@vitejs/devtools-oxc/vite'
import { defineConfig } from 'vite'

export default defineConfig({
  plugins: [DevTools(), DevToolsOxc()],
})

It also runs standalone from the CLI — generate lint logs with npx @vitejs/devtools-oxc lint, then launch the UI with npx @vitejs/devtools-oxc.
