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. This can be seen in the example below.

This makes it especially useful for consuming godot data sent using the redis reactor.

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));

Which outputs:

obj { test: 'value', other: 'otherValue' }

Test

npm test
