launch-editor-middleware

Express middleware that opens files in the user's default editor when requested via a URL. Version 2.13.2 is current; it is part of the launch-editor ecosystem by Evan You. It relies on launch-editor to resolve the editor and is typically used in development tooling like Vue CLI or Vite to open source files directly from the browser console. No active development fork, but stable and widely used. Differentiator: simple integration with Express, zero-config editor detection.
