WebSub Push Server

Node.js push notification server which is compatible with WebSub protocol.

1. Mobile application (App) that wants to receive push notifications from WebSub Publisher (Publisher) may register itself with this Push Server (Server).
2. Server will subscribe on behalf of App with Publisher.
3. When Publisher publishes something, Server will forward the information to App via one of the supported push services.

Deployment

Notes:

• By default, there'll be 1 worker to push notifications by npm start. It is possible to have multiple separated instances of workers by using npm run worker. In that case, it's recommended to disable the default one by setting env var CONFIG_PUSH_QUEUE_WORKER=false.
