utopia_queue 0.3.0

Light and easy to use queue library for Dart server projects

Utopia Queue

Utopia queue is a powerful queue library. It is designed to be simple and easy to learn and use. It is built on top of redis.

It is super helpful to build background workers to handle long running tasks. For example in your API server, you can use a emails queue to handle sending emails in the background.

Getting started

First add the dependency in your pubspec.yaml

dependencies:
  utopia_queue: ^0.2.0

Now, in main.dart, you can start a server as the following.

import 'package:utopia_queue/utopia_queue.dart';

void main(List<String> arguments) async {
  final connection = ConnectionRedis('localhost', 6379);
  final Server server = Server(connection, queue: 'myqueue');

  server.job().inject('message').action((Message message) {
    print(message.toMap());
    // Do something with the message
  });
  server.start();
}

To send a message to the queue, use the following code.

import 'dart:io';
import 'dart:math';

import 'package:utopia_queue/utopia_queue.dart';

void sendMessage() async {
  final connection = ConnectionRedis('localhost', 6379);
  final client = Client(connection, queue: 'myqueue');
  await client
      .enqueue({'user': Random().nextInt(20), 'name': 'Damodar Lohani'});
  print('enqueued');
}
