Using CQRS in Symfony

Using CQRS in Symfony

Symfony is really great for building APIs very fast. Especially when using a CRUD / REST methodology. Simply because there are a lot of resources and tools build-in (API platform, request parameter converter, dependency injection into controller methods, ...).

Login throttling with Symfony and multiple server instances

Login throttling with Symfony and multiple server instances

Login throttling is possible with Symfony out of the box since 5.2. But the default configuration doesn't work as soon as you have multiple server instances. Why? Because it stores the relevant data on the local filesystem. So all we need to do is to exchange the

Symfony route parameter with slash as part of the parameter

Symfony route parameter with slash as part of the parameter

Usually the parameter you put in your url looks something like this: api_with_token: path: '/api/update-user/{token}' defaults: { _controller: App\Controller\UserController::update } methods: [POST] With this there is no way for your parameter to include a /.

UUIDs with serializer in Symfony

Using JWT for authentication in a SPA with Symfony is very easy thanks to bundles like FOSUserBundle, LexikJWTAuthenticationBundle and JWTRefreshTokenBundle.

Symfony http basic auth for debugging on live server

Symfony http basic auth for debugging on live server

When deploying a Symfony application you usually remove the dev environment for security reasons. Which of course makes it more difficult to debug the system if there are errors occurring. An easy solution would be to hide the dev environment behind a http basic auth. Unfortunately there doesn't
