Vulcain: HTTP/2 Server Push
 and the rise of client-driven REST APIs

Over the years, several formats have been created to fix performance bottlenecks of web APIs: the n+1 problem, over fetching, under fetching…
The current hipster solution for these problems is to replace the conceptual model of HTTP (resource-oriented), by the one of GraphQL.

It’s a smart network hack for HTTP/1… But a hack that comes with (too) many drawbacks when it comes to HTTP cache, logs, security…
Fortunately, thanks to the new features introduced in HTTP/2 and HTTP/3, it’s now possible to create REST APIs fixing these problems with ease and class.

Vulcain is a brand new Internet Draft allowing to create fast, idiomatic and client-driven REST APIs.
To do so, it relies on the Server Push feature introduced by HTTP/2+ and on the hypermedia capabilities of the HTTP protocol.

Better, Vulcain comes with an open source reverse proxy that you can put on top of any existing web API to instantly turn it into a Vulcain-compatible one!

HATEOAS is back, and it’s for the best!

[SymfonyCon] API Platform and Symfony: a Framework for API-driven Projects

Here are the slides of my talk during the Symfony Con Cluj. You can rate this talk on joind.in.

Install API Platform. Design the API data model as a set of tiny plain old PHP classes. Instantly get:

  • Fully featured dev environment with Symfony Flex and React containers, HTTP/2 and HTTPS support and a cache proxy
  • Pagination, data validation, access control, relation embedding, filters and error handling
  • Support for modern REST API formats: JSON-LD/Hydra, OpenAPI/Swagger, JSONAPI, HAL, JSON…
  • GraphQL support
  • An API responding in a just few milliseconds thanks to the builtin invalidation based cache mechanism
  • A dynamically created Material Design admini interface (a la Sonata / EasyAdmin – but 100% client-side) built with React.
  • Client apps skeletons: React/Redux, React Native, Vue.js, Angular…
  • Finally, deploy in 1 command on Google Container Engine or any cloud with a Kubernetes instance with the provided Helm chart.

Yes, you just need is describing a data model, just a few line of codes to get all of that!
