This is an example of a üWave web application using u-wave-http-api and u-wave-web. It's very barebones—for a more advanced example, check out wlk.yt. wlk.yt includes emoji and integrates with the https://hub.u-wave.net announce server.
Try it by running:
npm install # Pick a port you like! :) PORT=8080 npm start
Then open http://localhost:8080.
