Creating Your First Application with Lithe
Installation
Before you start building your application, you'll need to install Lithe. You can easily do this using Composer. Run the following command in your terminal:
composer create-project lithephp/lithephp my-first-app
Once the installation is complete, navigate into your project directory:
cd my-first-app
Now you're ready to begin developing your application!
Lithe allows you to create applications in a straightforward and flexible manner, 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, set up your application in the App.php
file by using the mount
method of the Lithe\App
class. Then, define your routes:
$app = \Lithe\App::mount();
$app->get('/', function ($req, $res) {
$res->send('Hello World!');
});
The App
class serves as the core of your Lithe application, managing all application logic and making it easier to create routes and handle requests and responses in an organized manner.
Functional Style: Practicality and Agility
If you prefer a minimalist approach, you can use the functional syntax, which doesn't require direct instantiation of the class:
use function Lithe\Orbs\Http\Router\get;
get('/', function ($req, $res) {
$res->send('Hello World!');
});
This method is quick and efficient, allowing you to write 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('Hello World!');
});
$app->listen();
With Lithe 2, this method is automatically invoked.
Serving the Application
Using the Built-in PHP Server
Testing your application locally is easy! With PHP installed, you can start the built-in server by executing 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 access 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/your-project/public/
-
Production:
http://your-domain.com/
Make sure that the server is pointing to the correct directory and is ready! Your application will be available to the world.
