Speedy API Client

An easy to use PHP client for Speedy REST API

Speedy client is a PSR-7 and PSR-18 compliant HTTP client that implements Speedy communication protocol. It has clean and consistent API, is fully unit tested and even comes with an example application to get you started.

Features

This library is compliant with PSR-7: HTTP message interfaces, PSR-17: HTTP Factories and PSR-18: HTTP Client

Installation

Using Composer:

$ composer require vasildakov/speedy

Usage

The Configuration

Let's presume that you are using PHP dotenv to load environment variables from a file named .env. In this case, you need to add the following variables:

SPEEDY_USERNAME="username"
SPEEDY_PASSWORD="password"
SPEEDY_LANGUAGE="EN"

The next step is to create a new Configuration instance like in the example bellow:

<?php

// configuration
$configuration = new Configuration(
    username: $_ENV['SPEEDY_USERNAME'],
    password: $_ENV['SPEEDY_PASSWORD'],
    language: $_ENV['SPEEDY_LANGUAGE']
);

Configuring Speedy Client

The final step is to configure the Speedy client. The client can be configured with any PSR-18 HTTP Client and PSR-17 HTTP Factory:

Example with Guzzle and Laminas Diactoros

<?php

use GuzzleHttp\Client;
use Laminas\Diactoros\RequestFactory;

$client  = new Client(); // PSR-18 HTTP Client
$factory = new RequestFactory(); // PSR-17 HTTP Factory
$speedy  = new Speedy($configuration, $client, $factory);

Example with Symfony HTTP Client and Nyholm HTTP Factory

<?php

use Nyholm\Psr7\Factory\Psr17Factory;
use Symfony\Component\HttpClient\Psr18Client;

$client  = new Psr18Client(); // PSR-18 HTTP Client
$factory = new Psr17Factory(); // PSR-17 HTTP Factory
$speedy  = new Speedy($configuration, $client, $factory);

Making a Request

Once you have configured the client, you can proceed to make your first request. By default, each method returns the data in JSON, which can then be utilized as a simple PHP array or deserialized into the PHP model.

<?php

// use an array
$request = new GetContractClientsRequest(clientSystemId: "1234567");
$json = $speedy->getContractClient($request);
$array = json_decode($json, true);

Processing the Response

The client API always returns the raw JSON response received from the endpoint. The JSON can be used as it is, decoded into a PHP associative array, or deserialized into a model object.

Deserialization can be achieved in two different ways: 1) by using the serializer, or 2) by decorating the original Speedy client with the SpeedyModelDecorator.

Using serializer:

<?php

$json = $speedy->getContractClient($request); # json

$serializer = (new SerializerFactory())(); # JMS\Serializer\SerializerInterface

$response = $serializer->deserialize(
    data: $json, 
    type: GetContractClientsResponse::class, 
    format: 'json'
); # GetContractClientsResponse

Instead of calling the serializer every time, you can enhance the original Speedy client by decorating it with the SpeedyModelDecorator. This enhancement makes the responses more convenient, predictable and easy to use.

<?php

$decorator = new SpeedyModelDecorator(
    new Speedy($configuration, $client, $factory)
);

/** @var GetContractClientsResponse $response */
$response = $decorator->getContractClient(new GetContractClientsRequest());

Using the model

<?php

// @var ArrayCollection $collection
$collection = $response->getClients();
foreach ($collection as $client) {
    dump($client); # Model\Client
    dump($client->getClientName());
    dump($client->getAddress()); # Model\Address
    dump($client->getAddress()->getSiteName()); # string
    dump($client->getAddress()->getPostcode()); # string 
}
