Laravel Consuming API

This project shows how to consume external APIs in Laravel. It implements practical examples and uses Saloon to make HTTP requests to the GitHub API.

Features

• ✅ Laravel 11
• ✅ Saloon 3
• ✅ PHPStan
• ✅ Laravel Pint (PHP Coding Standards Fixer)
• ✅ Pest (testing)

Installation

Install dependencies using Composer

composer install

Create your .env file from example

cp .env.example .env

Configuration

Configure the GitHub API token in the .env file

GITHUB_TOKEN=xxx

Integration GitHub API with Saloon

Building the Interface

There is GitHub interface in an app/Contracts directory. This interface will define the methods that we want our integration service class to have.

It looks like this:

namespace App\Contracts;

use App\Collections\GitHub\RepoCollection;
use App\DataTransferObjects\GitHub\CreateRepoData;
use App\DataTransferObjects\GitHub\RepoData;
use App\DataTransferObjects\GitHub\UpdateRepoData;

interface GitHub
{
    public function getRepos(?int $perPage = null): RepoCollection;

    public function getRepo(string $owner, string $repoName): RepoData;

    /**
     * @return list<string>
     */
    public function getRepoLanguages(string $owner, string $repoName): array;

    /**
     * @throws \App\Exceptions\Integrations\GitHub\GitHubException
     */
    public function createRepo(CreateRepoData $data): RepoData;

    public function updateRepo(string $owner, string $repoName, UpdateRepoData $data): RepoData;

    /**
     * @throws \App\Exceptions\Integrations\GitHub\NotFoundException
     * @throws \App\Exceptions\Integrations\GitHub\UnauthorizedException
     */
    public function deleteRepo(string $owner, string $repoName): void;
}

Note that we use DTOs classes to better describe the data structure.

Creating the Integration Service Class

GitHubService is a class that implements the GitHub interface and uses Saloon to send HTTP requests.

Saloon

Thanks to the Saloon implementation we can use the functions:

• Authentication
• Sending requests
  • Fetching a single resource
  • Fetching a list of resources
  • Creating a new resource
  • Updating an existing resource
  • Deleting an existing resource
• Pagination
• Sending concurrent requests
• Middleware
• Plugins
• Error handling
• Retry requests
• Handling API rate limits
• Caching responses
• Testing API integrations
