How to Create Your First Application with Lithe

Creating Your First Application with Lithe

Installation

Before you start developing your application, you will need to install Lithe. You can do this easily using Composer. Run the following command in your terminal:

composer create-project lithephp/lithephp my-first-app

Once the installation is complete, navigate to your project directory:

cd my-first-app

Now you are ready to start developing your application!

Lithe allows you to create applications in a simple and flexible way, offering two writing styles: classic and functional. You can choose one or even combine both without losing efficiency.

Classic Style: Instantiating the Application

To start with the classic style, configure your application in the App.php file using the mount method of the LitheApp class. Then define your routes:

$app = \Lithe\App::mount();

$app->get('/', function ($req, $res) {
    $res->send('Olá, Mundo!');
});

The App class is the heart of your Lithe application, managing all application logic and facilitating the creation of routes and the handling of requests and responses in an organized way.

Functional Style: Practicality and Agility

If you prefer a more minimalist approach, you can use the functional syntax, which does not require a direct instance of the class:

use function Lithe\Orbs\Http\Router\get;

get('/', function ($req, $res) {
    $res->send('Olá, Mundo!');
});

This method is fast and efficient, allowing you to write more concise and expressive code.

Running the Application

After defining your first route, the next step is to run your application. If you are using the classic style, call the listen method to make Lithe start listening for requests:

$app = \Lithe\App::mount();

$app->get('/', function ($req, $res) {
    $res->send('Olá, Mundo!');
});

$app->listen();

With Lithe 2, this method is invoked automatically.

Serving the Application

Using the Integrated PHP Server

Testing your application locally is easy! With PHP installed, you can start the integrated server by running the following command:

php line serve

This will start the server on port 8000. To change the port, simply pass the desired value as an argument:

php line serve 9000

Open your browser and visit http://localhost:9000/ to see your application in action!

Using Web Servers like Apache

If you prefer to run your application on a web server like Apache, the entry point will be the public directory. Adjust the URL settings according to your environment:

• Local Environment: http://localhost/seu-projeto/public/
• Production: http://seu-dominio.com/

Make sure the server is pointing to the correct directory and you're good to go! Your application will be available to the world.
