What is LocatorJS?
LocatorJS is an open-source developer tool that bridges the gap between the rendered UI and the source code. By simply clicking on any component in the browser, developers can instantly navigate to its corresponding code in their IDE. This eliminates time wasted searching through file trees or manually tracing component hierarchies.
It supports multiple frameworks including React, Preact, Solid, Vue, and Svelte. LocatorJS can be used as a browser extension (compatible with Chrome, Edge, Brave, Opera, and Firefox) or integrated directly as a library. The tool works out of the box with popular React setups like Vite, Next.js, and Create React App, and offers custom configuration for other frameworks.
