Watch a longer video (English)!
Watch a French version.
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!
