Built on top of Symfony, API Platform lets you stand up a rich, hypermedia-driven API almost immediately – this course walks through building a real application with it end to end.

What you'll set up and use

  • API Platform integrated into a Symfony application
  • Swagger, OpenAPI, and JSON-LD/Hydra, and why each one matters
  • Defining and customizing ApiResources and their operations
  • Resource relations, embedded resources, and subresources
  • Filters, pagination, and validation for reliable, efficient data delivery
  • The Serializer, for controlling exactly which fields go in and out

By the end, you'll understand not just how to wire up API Platform, but why it saves so much of the boilerplate that a hand-rolled RESTful API usually requires – automated documentation included.

Who teaches API Platform: Serious RESTful APIs? SymfonyCasts

SymfonyCasts thumbnail

SymfonyCasts (formerly KnpUniversity) is a US-based PHP / Symfony training platform run by Ryan Weaver, a Symfony core team member. The platform is the closest thing to an official video-tutorial source for the Symfony framework — Ryan's tutorials are the path most working Symfony developers learned the framework through.

The CourseFlix listing carries five SymfonyCasts titles: Symfony 5 Fundamentals — Services, Config & Environments, API Platform — Serious RESTful APIs, Messenger! Queue Work for Later, phpspec — Testing / Designing with a Bite, and the SymfonyCon 2018 Lisbon Conference Videos. Material is paid and aimed at PHP developers building production Symfony applications.

For broader content, see CourseFlix's Symfony and PHP category pages where SymfonyCasts material sits alongside the wider PHP teaching community.
