@eigenspace/sse-emitter v1.0.7

About

This is a simple SSE emitter service which sends events. 1. Easily integrates with Express 2. Generates ids for messages automatically 3. Provides endless connection 4. Reduces any delays in data transportation 5. Triggers default event handler onmessage

Usage

1. Create an instance:

   private sseEmitter = new SseEmitter();

2. Assign it on a GET-route:

   this.app.get(environment.routes.events.base, this.sseEmitter.init.bind(this.sseEmitter));

3. Send any messages in any structure you need:

   this.sseEmitter.send({ 
       type: 'ON_ENTITY_SAVED', 
       content: { id: 228, name: 'Nikita' }
   });

4. On the client side you will get a message as described above. You should just add a handler on the default message event. For instance, on browser implementation it is:

   this.sseEmitter.onmessage = (event) => console.log(event.data)
