Vulcain is a protocol built using HTTP/2 which bring the benefits of GraphQL to conventional REST-based APIs.
“Over the years, several formats have been created to fix performance bottlenecks impacting web APIs: over fetching, under fetching, the n+1 problem…
Current solutions for these problems (GraphQL, JSON:API’s embeded resources and sparse fieldsets, …) are smart network hacks for HTTP/1. But these hacks that come with (too) many drawbacks when it comes to HTTP cache, logs and even security.
Fortunately, thanks to the new features introduced in HTTP/2, it’s now possible to create true REST APIs fixing these problems with ease and class! Here comes Vulcain!”
