关于此扩展
Click straight from your running app to your code.
Hold Alt (Option on Mac) while hovering yoement under the cursor is highlighted withits component name and source file. Alt+click opens that file in your editor at the exact line.
WORKS WITH YOUR FRAMEWORK — AUTOMATICALLY
ComponentLocator detects how your app was ategy, with zero configuration:
✔ Next.js — App Router and Pages Router, W8 & 19, Server Components (labeled with a"server" badge)
✔ React without Next.js — Vite, Create Rea
✔ Vue 2 & 3 — exact line/column when vite-plugin-vue-inspector or Vue DevTools is present
✔ Svelte 3/4/5 and SvelteKit — exact line/
✔ Astro — .astro templates and framework islands
WHY THIS EXTENSION
Tools built on React's old _debugSource fit 19 and Next.js App Router. This extension reads React 19's new owner stacks (_debugStack) and resolves original source positions through the dev serveown source-map endpoints (Next.js) or the Vite) — and uses each framework's nativedev metadata for Vue, Svelte and Astro.
HOW IT OPENS YOUR EDITOR
By default it auto-detects the dev server't.js, Vue CLI, Nuxt, Create React App) —the same mechanism as the framework's error overlay — so it respects your REACT_EDITOR / EDITOR environment variable. Or configure a custom URL schemef, or JetBrains IDEs.
PRIVACY & SCOPE

anywhere. Development use only: production.
