osmapp

OsmAPP

Let's create a universal app for OpenStreetMap ecosystem. It should be as easy to use as Google Maps, including clickable POIs and editing capabilites. Built with React, Next.js and Maplibre GL. See also SotM 2021 talk.

• master branch: https://osmapp.org
• examples: Empire State Building, Prague Castle or click just anything

Note: The OpenClimbing project was forked into a stand-alone repository to enable faster iterations.

How to contribute 🐱‍💻

You may add issues here on GitHub, or try to update the code in three simple steps:

1. edit code online with pencil icon (this opens a pull-request) ✏️
2. wait few minutes for a preview URL 💬
3. iterate 🔁

If you are a JS dev, you may also git clone / yarn / yarn dev
Or open OsmAPP in gitpod or GitHub Codespaces – full dev environment in your browser.
Consider setting NEXT_PUBLIC_ENABLE_TEST_API=true in .env.local for testing.
If Vercel build fails, please run yarn build locally to debug it.
