Composer Installation

The only thing you have to do is to run this command, and you're ready to go.

composer require codeigniter4/queue

A composer error occurred?

If you get the following error:

Could not find a version of package codeigniter4/queue matching your minimum-stability (stable).
Require it with an explicit version constraint allowing its desired stability.
  1. Run the following commands to change your minimum-stability in your project composer.json:

    composer config minimum-stability dev
    composer config prefer-stable true
  2. Or specify an explicit version:

    composer require codeigniter4/queue:dev-develop

The above specifies develop branch. See

Manual Installation

In the example below we will assume, that files from this project will be located in app/ThirdParty/queue directory.

Download this project and then enable it by editing the app/Config/Autoload.php file and adding the CodeIgniter\Queue namespace to the $psr4 array, like in the below example:


// ...

public $psr4 = [
    APP_NAMESPACE => APPPATH, // For custom app namespace
    'Config'      => APPPATH . 'Config',
    'CodeIgniter\Queue' => APPPATH . 'ThirdParty/queue/src',

// ...

Database Migration

Regardless of which installation method you chose, we also need to migrate the database to add new tables.

You can do this with the following command:

php spark migrate --all
