This extension brings the power of Slim for applications using Nette DI. It enables you to easily work with Slim middleware stack and develop your API easily.
The general idea has been discussed in this article. (Czech language)
The main idea is to delegate responsibilities of the code handling requests to separated middlewares. For example:
- authentication
- validation
- business logic
How middlewares in Slim work is described here.
Empowered by Nette DI and it's neon configuration syntax this package provides powerful and easy way to define your API.
So let's start!
composer require brandembassy/slim-nette-extension
Now register new extension by adding this code into your config.neon:
extensions:
slimApi: BrandEmbassy\Slim\DI\SlimApiExtension # Register extension
slimApi: # Configure it
slimConfiguration:
settings:
removeDefaultHandlers: true # It's recommended to disable original error handling
# and use your own error handlers suited for needs of your app.
apiDefinitionKey: api # Your API definition will be under this key in "parameters" section. Now let's say you want to make a REST endpoint creating channels, [POST] /new-api/2.0/channels
You need to define in parameters.api section in config.neon.
Both services and middlewares must be registered services in DI Container.
parameters:
api:
handlers:
notFound: App\NotFoundHandler # Called when not route isn't matched by URL
notAllowed: App\NotAllowedHandler # Called when route isn't matched by method
error: App\ApiErrorHandler # Called when unhandled exception bubbles out
routes:
new-api: # This is name of your API
"2.0": # Version of your API
'/channels': # Matched URL will be "your-domain.org/new-api/2.0/channels"
post:
# This is service will be invoked to handle the request
service: App\CreateChannelAction
# Here middleware stack is defined. It's evaluated from bottom to top.
middleware:
- App\SomeOtherMiddleware # last in row
- App\UsuallyRequestDataValidationMiddleware # second in row
- App\SomeAuthMiddleware # this one is called first
beforeRouteMiddlewares:
# this is called for each route, before route middlewares
- App\SomeBeforeRequestMiddleware
beforeRequestMiddlewares:
# this is called for each request, even when route does NOT exist (404 requests)
- App\SomeBeforeRouteMiddleware tests/Dummy/BeforeRequestMiddleware.phpYou can also reference the named service by it's name.
See tests/SlimApplicationFactoryTest.php and tests/config.neon for more examples.
Now you can simply get SlimApplicationFactory class from your DI Container (or better autowire it), create app and run it.
$factory = $container->getByType(SlimApplicationFactory::class);
$factory->create()->run();
