co-mongomq

co wrapper for mongomq package.

Quickstart

const MongoMQ = require('co-mongomq');
 
const queue = new MongoMQ();
yield queue.start();
 
// monitoring process
queue.on('test', function*(error, message) {
    // co context here, so you can yield :)
    console.log(message);
});
 
// emitting process
yield queue.emit('test', { my: 'message' });

Usage

Please refer to the documentation of MongoMQ.

Differences to MongoMQ

• require('co-mongomq') directly returns the MongoMQ property (no need to use .MongoMQ).
• new MongoMQ() options do not support autoStart. Start manually.
• .emit() requires a yield and returns as soon as the message was added to the database (or failed).
• .addListener() (aka .on()) takes a generator as handler which is run in a co context so you can use yield.
• .addListener() (aka .on()) does not have the third argument named next. It will be called implicitly unless the generator returns with false (and only false - not something falsey).
• .broadcast() requires a yield but does always return immediately since MongoMQ does not support a callback here. It's still asynchronous for forward compatibility.

Installation

$ npm install co-mongomq
