API reviews without a systematic checklist consistently miss the same categories: security aspects, error formats, performance and test coverage tend to get skipped under time pressure. A structured checklist makes reviews faster, more complete and repeatable, and ensures that no PR gets merged with a critical gap.
A convenient remember me feature and secure session handling are not mutually exclusive, once you know the right building blocks. This guide shows persistent remember me tokens instead of insecure signed cookies, protection against session fixation, and a timeout strategy that matches the actual sensitivity of the application.
A test that checks whether a message landed on a bus says nothing about whether the associated handler does the right thing. With InMemoryTransport and TraceableMessageBus, Symfony Messenger handlers can be tested synchronously, deterministically, and without RabbitMQ or Redis in the pipeline.
Synchronous systems scale up to a point, then HTTP requests grow too long, database connections pile up, and a single failing service blocks the entire system. Symfony Messenger solves exactly this problem through a clear separation of command, event and query, combined with asynchronous transports that deliver messages reliably even during system outages.
A Symfony Docker image that runs locally is far from production ready. Multi stage builds separate the build environment from the runtime, Composer caching shortens every build, and a non root user plus a healthcheck make the container operable. This article walks through building a lean, hardened Symfony Docker image step by step.
Anyone running a Symfony REST API without documentation leaves the tedious reverse engineering work to consumers and QA teams. NelmioApiDocBundle generates a complete OpenAPI 3.1 specification from PHP attributes and YAML configuration, including Swagger UI, JWT security schemes, and response schemas straight from the code.
Attribute routing covers the vast majority of applications, but it hits its limits once routes need to come from a database at runtime, for example for CMS pages or redirects. This article shows how a custom loader covers those cases, how custom requirements validate parameters with regex right inside routing, and how to reliably control ordering when routes overlap.
Symfony 7 makes Webpack Encore optional: AssetMapper manages JavaScript imports natively through importmap, and the Tailwind CSS Standalone CLI processes CSS without npm. The result is a modern frontend setup that needs no Node.js in the production build, simpler to deploy and simpler to maintain.
The Symfony profiler shows what happened during a request, but Blackfire shows why it took so long. With callgraphs, reference profiles and CI integration, Blackfire profiling exposes exactly which function calls are really slowing a Symfony application down.
Anyone repeating the same code across several Symfony projects should build a custom Symfony bundle. This article walks through the full directory structure, the bundle class, the Composer package and kernel registration, so recurring logic becomes a maintained, testable component.
