README

An API client written in PHP to interact with LibreTranslate, a free, open-source translation API.

Characteristics

• Translations between different languages ​​supported by LibreTranslate.
• Automatic language detection.
• Support for API Key, if needed.
• Easy setup and use.

Installation

You can install the client via Composer:

composer require malvik-lab/libre-translate-api-client

Initializing

<?php

require 'vendor/autoload.php';

use GuzzleHttp\Client as HttpClient;
use MalvikLab\LibreTranslateClient\Client;

// LibreTranslate server URL
$baseUrl = 'http://localhost:5000';

// If the server requires an API Key, enter it here.
// If the server is free (no need for API Key), pass `null` as a parameter.
$apiKey = null; // API Key (optional)

// Example 1: Minimal configuration (without API Key, if the server does not require it)
$client = new Client($baseUrl); // No API Key required

// Example 2: Configuration with API Key (if required by the server)
$client = new Client($baseUrl, $apiKey); // Pass the API Key (can be null)

// Example 3: Configuration with a custom Guzzle instance (for advanced customization)
$httpClient = new HttpClient(); // Custom Guzzle client (useful for adding middlewares, timeouts, etc.)
$client = new Client($baseUrl, $apiKey, $httpClient); // With API Key
// or
$client = new Client($baseUrl, null, $httpClient); // Without API Key (if server is free)
