minwq

Minimalistic Node.JS Work Queue, backed by Redis. (>=2.6.* redis required with Lua support)

npm install minwq

Usage

var minwq = require("minwq")

// Create a new store
var store= new minwq([options]);

// Optional
// You can provide a queue suffix for all jobs for namespacing purposes.
var store = new minwq({
    prefix: "myapp",
});

// If you need to provide custom redis clients (due to authentication or because you just want to), you can override createClient function of store;
store.createClient = function() {
    return redis.createClient(..whatever);
}

Pushing - Push a new job to a queue

  • queue [required] - Name of the queue
  • data [required] - Job payload
  • delay [optional] - Delay job execution (in milliseconds)
  • unique [optional] - If provided, only a single living job can have the unqiue token, additional push requests will fail.
  • priority [optional] - Integer, denoting the job priority. Higher gets executed first.
  • callback(err, jobid) - Gets called when the job is created

store.push({
    queue: "email",
    data: {
        to: "foo@bar.com",
        subject: "Foo",
        text: "Bar"
    },
    delay: 100,
    unique: "unqiue token",
}, callback);

Poping - Pop a job from queue

  • ttl [optional] - Job retry delay (in milliseconds).

If a job takes more than ttl milliseconds to complete, it will be requeued. No TTL means the hob will be removed from queue immediately when the pop function gets called.


store.pop({
    queue: "email",
    ttl: 10000
}, function(err, job) {
    // job.data contains the job payload
    console.log(job.data);

    // after finishing the job, you need to remove it explicitly from the queue:
    job.remove(callback);
});
