# Routing

Leaf router

Leaf API uses Leaf's router so be sure read the docs (opens new window).

Leaf API keeps all routes in the app/routes directory. All routes are defined the index.php file round in the routes directory, however, you can create files pertaining to a group of routes which allows you to break routes into groups.

# Basic Routing

Just as with base leaf, you can define routes using the leaf app instance or the leaf router module.

// $app instance (old)
$app->get('/user/{id}', function($id) {
  response()->json([
    "mesage" => "Your id is $id"
  ]);
});

// functional mode instance
app()->post('/save', function() {
  // 
});

// using controllers
$app->get('/user/{id}', 'Class@method');

// using the router class
Leaf\Router::get("/users", "Class@method");

The most basic app routes accept a URI and a closure, providing a very simple and expressive method of defining routes and behavior without complicated routing configuration files:

$app->get('/greeting', function() {
  echo "Hello there!";
});

# Available Router Methods

The router allows you to register routes that respond to any HTTP verb:

app()->get($uri, $callback);
app()->post($uri, $callback);
app()->put($uri, $callback);
app()->patch($uri, $callback);
app()->delete($uri, $callback);
app()->options($uri, $callback);

Sometimes you may need to register a route that responds to multiple HTTP verbs. You may do so using the match method. Or, you may even register a route that responds to all HTTP verbs using the any method:

app()->match('GET|POST', '/', function () {
  //
});

app()->any('/', function () {
  //
});

# Redirect Routes

If you are defining a route that redirects to another URI, you may use the $app->redirect method. This method provides a convenient shortcut so that you do not have to define a full route or controller for performing a simple redirect:

app()->redirect('/here', '/there');

By default, $app->redirect returns a 302 status code. You may customize the status code using the optional third parameter:

app()->redirect('/here', '/there', 301);

# Sub files

In the App/Routes directory, you'll find an index.php file, this is the entry point for your routes, however, you might want to seperate your routes to avoid having bloated files containing too many routes.

You simply need to create a file, eg: _user.php and add all your user specific routes in there.

Note that the _ is not compulsory, it's just a good naming convention inspired by SASS modules.

After creating the sub file, you just need to require it in the main route file index.php.
