Rollerworks RouteAutowiringBundle

The RollerworksRouteAutowiringBundle allows to import multiple route collections using an autowiring system.

For example you have BundleA which defines some routes, to use them you need to explicitly import them, but if you remove/disable the bundle the application breaks because it can't find the resource files anymore.

When you automatically enable them you can't keep the prefix consistent. And sometimes you rather don't want to enable all route collections.

How does it work?

In practice you define your routes as normal, but instead of importing them from a file or service you load them using the autowiring system.

Requirements

You need at least PHP 7.2 and the Symfony FrameworkBundle.

Installation

Open a command console, enter your project directory and execute the following command to download the latest stable version of this bundle:

$ php composer.phar require rollerworks/route-autowiring-bundle

This command requires you to have Composer installed globally, as explained in the installation chapter of the Composer documentation.

Basic usage

There are two parts to this bundle, registering and loading.

Routing schema's are kept per "routing-slot", which are automatically registered whenever you import a route collection.

Registering routes for loading

Say you have an AcmeShopBundle with the following route collections:

# Resources/config/routing/frontend.yml

_products:
    resource: "routing/frontend/products.yml"
    prefix:   /products

_cart:
    resource: "routing/frontend/cart.yml"
    prefix:   /cart

# Resources/config/routing/backend.yml

_products:
    resource: "routing/backend/products.yml"
    prefix:   /products

You can import them using the following snippet:

use Rollerworks\Bundle\RouteAutowiringBundle\RouteImporter;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Extension\Extension;

class AcmeShopExtension extends Extension
{
    // ...

    public function load(array $configs, ContainerBuilder $container): void
    {
        // ...

        $routeImporter = new RouteImporter($container);
        $routeImporter->addObjectResource($this);
        $routeImporter->import('@AcmeShopBundle/Resources/config/routing/frontend.yml', 'frontend');
        $routeImporter->import('@AcmeShopBundle/Resources/config/routing/backend.yml', 'backend');
    }

    // ...
}

The @AcmeShopBundle/Resources/config/routing/frontend.yml resource will be imported (or registered) in the 'frontend' routing-slot. And the @AcmeShopBundle/Resources/config/routing/backend.yml resource will be imported in the 'backend' routing slot.

Note:

Route resources follow the same logic as the Symfony routing system, @AcmeShopBundle resolves the to full path of the AcmeShopBundle.

Tip: You can import multiple routing resources per slot 👍

$routeImporter->import('@AcmeShopBundle/Resources/config/routing/frontend.yml', 'frontend');
$routeImporter->import('@AcmeShopBundle/Resources/config/routing/extra.yml', 'frontend');

The import will try to guess the correct resource-type, but for special ones (like a service) you need to provide the type in the third parameter:

$routeImporter->import('@AcmeShopBundle/Resources/config/routing/frontend.yml', 'frontend', 'yaml');

Import multiple resources to the same slot? Provide a default (for the current instance):

$routeImporter = new RouteImporter($container, 'frontend');
$routeImporter->import('@AcmeShopBundle/Resources/config/routing/frontend.yml'); // is imported in the frontend slot
$routeImporter->import('@AcmeShopBundle/Resources/config/routing/backend.yml', 'backend'); // is imported in the backend slot

Resource tracking

The routing system is not directly aware of any related classes when registering your route imports (using the RouteImporter). Therefor removing a Bundle or changing configuration may not directly reload your routing schema (unless you use the cache:clear command).

You need to register the Extension class and any other related class, like your Bundle's Configuration class, if changing them may cause a different routing import schema.

To register an object (like the Extension class, and its parent(s)) use:

$routeImporter->addObjectResource($this);

Or to register a class (and its parent(s)):

$routeImporter->addObjectClass($this);

To register any Symfony supported Resource (full path) use:

$routeImporter->addResource(new FileResource('my-file-file-path.yml'));

Note:

Resources are only tracked when debugging is enabled.

Imported routes (->import(...)) are automatically tracked by the routing system, only classes related to the import registering should be registered for tracking.

Loading registered routes

Ones your routes are imported into there routing-slot's it's time to load them into the application's routing schema.

Normally you would use something like this:

# app/config/routing.yml

_frontend:
    resource: "frontend.yml"
    prefix:   /

_backend:
    resource: "frontend.yml"
    prefix:   /

# frontend.yml

_AcmeShop:
    resource: "@AcmeShopBundle/Resources/config/routing/frontend.yml"

# backend.yml

_AcmeShop:
    resource: "@AcmeShopBundle/Resources/config/routing/backend.yml"

But instead you load them using the autowiring loader:

# app/config/routing.yml

_frontend:
    resource: "frontend"
    type: rollerworks_autowiring
    prefix:   /

_backend:
    resource: "backend"
    type: rollerworks_autowiring
    prefix: backend/

That's it! All the routes that were imported in the 'frontend' and 'backend' slots are now loaded into the applications routing schema.

But wait, what if there are no routes imported for the slot?

Then nothing happens, this bundle is designed to make configuration easy. When there are no routes imported for the slot it simple returns an empty Collection, which in practice is never used.

Third-party import example

As the Symfony routing system allows to load any route resource from a routing file you can actually load a routing-slot from within from another routing-slot.

Say you want to allow others to "extend" your bundle's routing schema:

First import the main parts in the application's routing file:

# app/config/routing.yml

_frontend:
    resource: "frontend"
    type: rollerworks_autowiring
    prefix:   /

_backend:
    resource: "frontend"
    type: rollerworks_autowiring
    prefix: backend/

In AcmeShopBundle define the following routes, and import them (extension snippet omitted).

# Resources/config/routing/frontend.yml

_products:
    resource: "routing/frontend/products.yml"
    prefix:   /products

_cart:
    resource: "routing/frontend/cart.yml"
    prefix:   /cart

# Resources/config/routing/frontend.yml

_products:
    resource: "routing/backend/products.yml"
    prefix:   /products

# Load other routing schema's from the routing-slot
_imports:
    resource: "acme_shop.frontend"
    type: rollerworks_autowiring

Others can now easily import there routing schema(s) into the acme_shop.frontend routing-slot.

Versioning

For transparency and insight into the release cycle, and for striving to maintain backward compatibility, this package is maintained under the Semantic Versioning guidelines as much as possible.

Releases will be numbered with the following format:

<major>.<minor>.<patch>

• Breaking backward compatibility bumps the major (and resets the minor and patch)
• New additions without breaking backward compatibility bumps the minor (and resets the patch)
• Bug fixes and misc changes bumps the patch
