Web Push Demo

This repository is a basic Node.js app showing the different parts needed to implement web push notifications.

The app consists of three components:

1. The server (everything under src), which is responsible for serving the app assets as well as sending synthetic push notificatoins.
2. The main script (static/main.js), which runs in the browsing context and is responsible for managing the user interface and starting up the service worker.
3. The service worker (static/service-worker.js), which runs as a service worker, and is mainly responsible for receiving push notifications sent by the server.

Setting things up

1. You'll need to generate VAPID keys. See the config/vapid.json.example for reference. These keys need to be at config/vapid.json. The script at scripts/keygenHelper.mjs should provide suitable values.
2. Run the script at src/index.mjs directly or using npm run start. The app will start by default at port 5000, which can be changed by setting the PORT environment variable.
