Agenda is a light-weight job scheduling library for Node.js.

It offers:

• Minimal overhead. Agenda aims to keep its code base small.
• Mongo backed persistance layer.
• Promises based API
• Scheduling with configurable priority, concurrency, and repeating
• Scheduling via cron or human readable syntax.
• Event backed job queue that you can hook into.
• Optional standalone web-interfaces (see agendash and agenda-ui)

Installation

Install via NPM

npm install agenda

You will also need a working mongo database (2.6+) to point it to.

Example Usage

var mongoConnectionString = "mongodb://127.0.0.1/agenda";

var agenda = new Agenda({db: {address: mongoConnectionString}});

// or override the default collection name:
// var agenda = new Agenda({db: {address: mongoConnectionString, collection: "jobCollectionName"}});

// or pass additional connection options:
// var agenda = new Agenda({db: {address: mongoConnectionString, collection: "jobCollectionName", options: {server:{auto_reconnect:true}}}});

// or pass in an existing mongodb-native MongoClient instance
// var agenda = new Agenda({mongo: myMongoClient});

agenda.define('delete old users', function(job, done) {
  User.remove({lastLogIn: { $lt: twoDaysAgo }}, done);
});

agenda.on('ready', function() {
  agenda.every('3 minutes', 'delete old users');

  // Alternatively, you could also do:
  agenda.every('*/3 * * * *', 'delete old users');

  agenda.start();
});
