samair/gitparse — reverse-engineered prompt

Build me a simple web app called gitparse that lets someone paste a public GitHub repository URL and get back prompt friendly text they can copy into an AI chat. It should feel lightweight and practical, with one main page, a clear input box, a submit button, and an output area showing the parsed repo contents in a clean readable format.

Use Java for the backend and keep it easy to run locally on port 7878. The app should fetch the repo, read useful files, avoid junk like build folders and git internals, and combine the contents into one text response that is good for prompting an LLM. Also include a basic API endpoint like /api/v1/parse/{repoUrl} so it can be called with curl.

Make the UI simple, include basic error messages for bad URLs or failed fetches, and make sure there’s a straightforward local run option and Docker build support.
