How to Include External Routing Resources

Simple applications can define all their routes in a single configuration file - usually config/routes.yaml (see Routing). However, in most applications it's common to import routes definitions from different resources: PHP annotations in controller files, YAML or XML files stored in some directory, etc.

This can be done by importing routing resources from the main routing file:

YAML
XML
PHP

        # config/routes.yaml
app_file:
    # loads routes from the given routing file stored in some bundle
    resource: '@AcmeOtherBundle/Resources/config/routing.yml'

app_annotations:
    # loads routes from the PHP annotations of the controllers found in that directory
    resource: '../src/Controller/'
    type:     annotation

app_directory:
    # loads routes from the YAML or XML files found in that directory
    resource: '../legacy/routing/'
    type:     directory

app_bundle:
    # loads routes from the YAML or XML files found in some bundle directory
    resource: '@AppBundle/Resources/config/routing/public/'
    type:     directory

$routes = new RouteCollection();
$routes->addCollection(
    // loads routes from the given routing file stored in some bundle
    $loader->import("@AcmeOtherBundle/Resources/config/routing.yml")

    // loads routes from the PHP annotations of the controllers found in that directory
    $loader->import("../src/Controller/", "annotation")

    // loads routes from the YAML or XML files found in that directory
    $loader->import("../legacy/routing/", "directory")

    // loads routes from the YAML or XML files found in some bundle directory
    $loader->import("@AppBundle/Resources/config/routing/public/", "directory")
);

return $routes;
    

Note

When importing resources from YAML, the key (e.g. app_file) is meaningless. Just be sure that it's unique so no other lines override it.

Prefixing the URLs of Imported Routes

You can also choose to provide a "prefix" for the imported routes. For example, suppose you want to prefix all application routes with /site (e.g. /site/blog/{slug} instead of /blog/{slug}):

    xsi:schemaLocation="http://symfony.com/schema/routing
        http://symfony.com/schema/routing/routing-1.0.xsd">

    <import
        resource="../src/Controller/"
        type="annotation"
        prefix="/site" />
</routes>

        // config/routes.php
use Symfony\Component\Routing\RouteCollection;

$app = $loader->import('../src/Controller/', 'annotation');
$app->addPrefix('/site');

$routes = new RouteCollection();
$routes->addCollection($app);

return $routes;
    

The path of each route being loaded from the new routing resource will now be prefixed with the string /site.

Note

If any of the prefixed routes defines an empty path, Symfony adds a trailing slash to it. In the previous example, an empty path prefixed with /site will result in the /site/ URL. If you want to avoid this behavior, set the trailing_slash_on_root option to false:

The trailing_slash_on_root option was introduced in Symfony 4.1.

Prefixing the Names of Imported Routes

You also have the possibility to prefix the names of all the routes defined in a controller class or imported from a configuration file:

    public function index()

$app = $loader->import('../src/Controller/', 'annotation');
$app->addNamePrefix('blog_');

$collection = new RouteCollection();
$collection->addCollection($app);

return $collection;
    

In this example, the names of the routes will be blog_index and blog_post.

4.1

The option to prefix route names in YAML, XML and PHP files was introduced in Symfony 4.1. Previously only the @Route() annotation supported this feature.
