primus-rooms-adapter

In-memory default adapter for primus-rooms.

Installation

$ npm install primus-rooms-adapter

Usage

Use this adapter as an abstract class for creating your own custom 'primus-rooms' adapter.

var util = require('util');
var Adapter = require('primus-rooms-adapter');

function MyAdapter() {
  Adapter.call(this);
}

util.inherits(MyAdapter, Adapter);

Adapter.prototype.broadcast = function broadcast(data, opts, clients) {
  // Do my custom broadcast here, it could be sending to a database
};

Then you can set your custom adapter for rooms, like this:

primus.use('rooms', Rooms);

// by setting the property
primus.adapter = new MyAdapter();

or pass the adapter instance as argument to Primus like so:

var myAdapter = new MyAdapter();
var primus = new Primus(url, {
  transformer: 'sockjs',
  rooms: { adapter: myAdapter }
});
