PHP Client for Joystick Remote Config

GitHub Actions Latest Stable Version Total Downloads License

Use Joystick to easily manage and integrate JSON remote configs with your PHP projects. Joystick is a modern remote config platform to manage all of your configurable parameters behind one API. We are natively multi-environment, preserve your version history, have advanced work-flow & permissions management, and much more.

This library simplifies how your PHP project can communicate with Joystick API to get remote configs over REST API.

PHP 7.2 and later


You can install the package via Composer:

composer require getjoystick/joystick-php

We will try to find the PSR-18 compatible HTTP client within your dependencies using php-http/discovery, if you don't have one installed, just run this command to install Guzzle HTTP client:

composer require guzzlehttp/guzzle


To use the client, use Composer's autoload:

require_once 'vendor/autoload.php';

Simple usage looks like this:

$config = \Joystick\ClientConfig::create()->setApiKey(getenv('JOYSTICK_API_KEY'));

$client = \Joystick\Client::create($config);

$getContentsResponse = $client->getContents(['content-id1', 'content-id2']);


Requesting Content by single Content Id

$getContentResponse = $client->getContent('content-id1');

Specifying additional parameters:

When creating the ClientConfig object, you can specify additional parameters which will be used by all API calls from the client, for more details see API documentation:

$config = \Joystick\ClientConfig::create()
    ->setCacheExpirationSeconds(600) // 10 mins
        'param1' => 'value1',
        'param2' => 'value2',



In most of the cases you will be not interested in the full response from the API, but if you're you can specify fullResponse option to the client methods. The client will return you raw API response:

$getContentResponse = $client->getContent('content-id1', ['fullResponse' => true]);
// OR
$getContentsResponse = $client->getContents(['content-id1', 'content-id2'], ['fullResponse' => true]);


When true, we will pass query parameter responseType=serialized to Joystick API.

$getContentResponse = $client->getContent('content-id1', ['serialized' => true]);
// OR
$getContentsResponse = $client->getContents(['content-id1', 'content-id2'], ['serialized' => true]);


If you want to ignore existing cache and request the new config – pass this option as true.

$getContentResponse = $client->getContent('content-id1', ['refresh' => true]);
// OR
$getContentsResponse = $client->getContents(['content-id1', 'content-id2'], ['refresh' => true]);

This option can be set for every API call from the client by setting setSerialized(true):

$config = \Joystick\ClientConfig::create()


By default, the client uses array caching, which means that if you build the HTTP application where each process exits after the request has been processed – the cache will be erased after the process is finished.

You can specify your cache implementation which conforms PSR-16.

See examples/file-cache for more details.

Clear the cache

If you want to clear the cache – run $client->clearCache().

Note that we will call clear() on the PSR-16 interface. Make sure that you use different cache instances in different places of your app

HTTP Client

If you want to provide custom HTTP client, which may be useful for use-cases like specifying custom proxy, collecting detailed metrics about HTTP requests,

You can specify your HTTP client implementation which conforms PSR-18.

See examples/custom-http-client for more details.
