PHP Session Management on Lithe: From Basic Configuration to Advanced Use

When we talk about web applications, one of the first needs is to maintain the user's information while he navigates through the pages. That's where session management in Lithe comes in, allowing you to store data like login information or user preferences.

Simple and Quick Installation

To start using sessions in Lithe, you just need to install the sessions middleware via Composer. Just run the following command in the terminal within your project:

composer require lithemod/session

This will install everything you need. Nothing complicated, right?

Configuration in a Few Steps

With the middleware installed, you need to configure it in your project. But don't worry, this is quite easy! You simply add the middleware to your application using the use() method. See a basic example:

use function Lithe\Middleware\Session\session;

$app->use(session());

Ready! The session is configured and ready to use. If you need to adjust some details such as the session duration, the domain, or if the cookie should only be sent via HTTPS, just pass these parameters in the configuration:

$app->use(session([
    'lifetime' => 3600, // Sessão de 1 hora
    'secure' => true,   // Apenas em conexões seguras
    'httponly' => true, // Acessível só por HTTP
]));

Working with Sessions: The Basics

Now that everything is configured, let's get to practice. You can easily store and retrieve session information in Lithe routes. For example, to save the username:

$app->get('/set-usuario', function ($req, $res) {
    $req->session->put('usuario', 'John Doe');
    return $res->send('Usuário salvo na sessão!');
});

And to get the name back:

$app->get('/get-usuario', function ($req, $res) {
    $usuario = $req->session->get('usuario', 'Usuário não encontrado');
    return $res->send('Usuário: ' . $usuario);
});

It’s that simple. Session management in Lithe is straight to the point.

Tips for Using Sessions Efficiently

• Keep the session short: Long sessions can be a security risk, so adjust the lifetime carefully.
• Always use HTTPS: If your application is in production, make sure to use secure => true to ensure that session cookies are transmitted securely.
• Session Cleanup: Remember to always remove session data that is no longer needed to avoid overloading storage.

Beyond the Basics: Advanced Functions

If you need something more advanced, Lithe also allows you to regenerate the session ID for greater security, check if the session is active, or even destroy the entire session with ease:

$app->get('/destruir-sessao', function ($req, $res) {
    $req->session->destroy();
    return $res->send('Sessão destruída!');
});

This flexibility ensures that you have full control over the session state and user experience in your application.
