Queue Jobs for Codeigniter 4

Queue Jobs module for CodeIgniter 4 with CLI Persistors:

1. Codeigniter
   • MySQLi
   • PDO
   • PostgreSQL
   • Oracle
   • ODBC
   • ....
2. PDO (Does not use a codeigniter modeling system and is self-contained)
3. Redis //TODO: will be added

I look forward to every help, further development and recommendation

Installing

install this package

$ composer require codeigniterextqueue

or

$ composer require codeigniterext/queue:dev-master

Now you can use the following commands from the command prompt

$ php spark queue:delete
$ php spark queue:deleteall
$ php spark queue:forget
$ php spark queue:forgetall
$ php spark queue:publish
$ php spark queue:resetall
$ php spark queue:retry
$ php spark queue:run
$ php spark queue:work

---

Configuration

Run the following command from the command prompt, and it will copy queue migration (20190526184519_queue_tasks.php) and config (Queue.php) into your application

Then in your Config/Modules.php, change this :

public $enabled = true;
public $discoverInComposer = true;

Then

php spark queue:publish

NOTE: If you do not want to use a codeigniter persistor, simply confirm the Publish Config file and type in Publish queue migration: n

finally go to config file and edit that

---

Use it

1. Codeigniter Persistor

in queue config file you must enter codeigniter as connection:

$queueConnection = 'codeigniter';

Now use the following commands from the command prompt to migrate queue table

NOTE: You must have previously entered the command php spark queue: publish and type in Publish queue migration: y

php spark migrate:latest

---

2. PDO Persistor

in queue config file you must enter PDO as connection:

$queueConnection = 'pdo';

Create a table with the following SQL code:

 CREATE TABLE IF NOT EXISTS `queue_tasks` (
    `id` INT NOT NULL AUTO_INCREMENT,
    `name` VARCHAR(255) NOT NULL,
    `method_name` VARCHAR(255) NULL,
    `data` TEXT NULL,
    `priority` TINYINT NOT NULL,
    `unique_id` VARCHAR(32) NULL,
    `created_at` DATETIME NOT NULL,
    `is_taken` TINYINT(1) NOT NULL DEFAULT 0,
    `error` TINYINT(1) NOT NULL DEFAULT 0,
    PRIMARY KEY (`id`))
  ENGINE = InnoDB;

Add a task in queue

...
use CodeigniterExt\Queue\Queue;
use CodeigniterExt\Queue\Task;
...

$queue = new Queue();

$task = new Task;

$task
    ->setName('App/Controllers/SendMail')
    ->setData(
        array(
            'to'        => 'example@domain.com',
            'from'      => 'your@email.com',
            'subject'   => 'Hi!',
            'text'      => 'It is your faithful Queue!'
        )
    )
    ->setPriority(Task::PRIORITY_NORMAL);

// Queue it
$queue->addTask($task);

---

Run the worker

php spark queue:work

To keep the queue:work process running permanently in the background, you should use a process monitor such as Supervisor to ensure that the queue worker does not stop running.
