RouteMapper

RouteMapper helps frontend developers quickly map live application URLs to likely source file locations used in file-based routing frameworks.

Instead of manually reconstructing route paths, RouteMapper converts the current page URL into a framework-specific file path and copies it directly to the clipboard.

Supported Frameworks

• Next.js App Router
• Next.js Pages Router
• Remix
• SvelteKit
• Nuxt
• Astro
• SolidStart

Why It Exists

Working across large frontend codebases often requires mentally mapping browser routes back to source files.

RouteMapper speeds up that workflow by:

• reducing repetitive path reconstruction
• normalizing dynamic route segments
• improving navigation across unfamiliar projects
• simplifying multi-framework development workflows

How It Works

1. Open a page in your local/dev/staging app
2. Select a framework
3. Click the extension icon
4. RouteMapper generates the matching route file path
5. The generated path is copied to the clipboard
6. A confirmation toast appears
