Subscribe-stream NPM

subscribe-stream

A simple Readable object stream that consumes the data published to a specific redis pub/sub channel using node_redis.

note: We assume that it is a stringified json object coming through the pub/sub channel that is again parsed into an object because they are much nicer to deal with.

Example

var redis = require('redis'),
    subscribeStream = require('../');

var stream = subscribeStream({ subscription: 'hithere' });

var client = redis.createClient();

var testObj = {
  test: 'value',
  other: 'otherValue'
};

stream.on('readable', function () {
  var obj = stream.read();
  console.log('obj', obj);
});

client.publish('hithere', JSON.stringify(testObj));
