Rethinking API Platform Filters

API Platform 4.1 and 4.2 unveils a revamped filter system featuring a brand-new syntax, inspired by the advancements introduced with Laravel support in version 4.0. These enhancements not only make filters more intuitive, flexible, and powerful for developers but also significantly evolve the codebase.

In this talk, we’ll walk through my contribution to this transformation — from identifying the limitations of the previous approach to designing and implementing a simplified, consistent solution.

Using practical examples, we’ll explore how these updates can streamline your API projects and reduce development complexity. To wrap up, we’ll discuss the next steps and potential enhancements planned for the filter system.

Whether you’re new to API Platform or an experienced user, this session will provide valuable insights, helping you leverage these improvements for faster and cleaner API development.
