Labrador Core

PHP Unit Testing & Code Lint GitHub release GitHub license

An opinionated, asynchronous micro-framework written on top of amphp. Built using SOLID principles, unit testing, and a modular ecosystem Labrador aims to be a production-ready framework for creating asynchronous PHP applications. Labrador Core serves as the foundation for this framework and provides important key concepts for building apps with Labrador.


Composer is the only supported method for installing Labrador packages.

composer require cspray/labrador

Quick Start

If you'd rather get started quickly without having to read a bunch of documentation the code below demonstrates how to quickly get an Application implemented and running. Otherwise, we recommend checking out the Documentation for more detailed information, and a complete guide to getting started.


// app.php in your project's root directory

require_once __DIR__ . '/vendor/autoload.php';

use Cspray\Labrador\AbstractApplication;
use Cspray\Labrador\EnvironmentType;
use Cspray\Labrador\CoreApplicationObjectGraph;
use Cspray\Labrador\Engine;
use Cspray\Labrador\StandardEnvironment;
use Amp\Promise;
use Amp\Delayed;
use Amp\Log\StreamHandler;
use Auryn\Injector;
use Monolog\Logger;
use function Amp\call;
use function Amp\ByteStream\getStdout;

class HelloWorldApplicationObjectGraph extends CoreApplicationObjectGraph {

    public function wireObjectGraph() : Injector {
        $injector = parent::wireObjectGraph();

        // wire up your app's dependencies

        return $injector;


class HelloWorldApplication extends AbstractApplication {

    protected function doStart() : Promise {
        return call(function() {
            yield new Delayed(500);  // just to show that we are running on the Loop
            $this->logger->info('Hello Labrador!');


$environment = new StandardEnvironment(EnvironmentType::Development());
$logger = new Logger('labrador.hello-world', [new StreamHandler(getStdout())]);

$injector = (new HelloWorldApplicationObjectGraph($environment, $logger))->wireObjectGraph();

$app = $injector->make(HelloWorldApplication::class);
$engine = $injector->make(Engine::class);



Labrador packages have thorough documentation in-repo in the docs/ directory. You can also check out the documentation online at


All Labrador packages adhere to the rules laid out in the Labrador Governance repo
