history
Project history and usage
Vulcain is a Go project and protocol for client-driven REST APIs. It tries to solve common API performance problems such as under-fetching, over-fetching, and the n+1 request pattern while staying close to HTTP, hypermedia links, preload hints, 103 Early Hints, and HTTP/2 server push.
Project history
The public repository was created in September 2019 under Kévin Dunglas's GitHub account. The README presents Vulcain as both a protocol and a reference gateway server: a Caddy web server module that can sit in front of an existing API and make it Vulcain-compatible.
The project was published as an Internet-Draft maintained from the same repository, which is notable for a small API tooling project: the author framed Vulcain as a protocol-level alternative to application-specific API query layers rather than just another gateway implementation.
How it is used
A Vulcain client asks for related resources with a `Preload` header or query parameter, and can also request selected fields with a `Fields` header. The gateway follows hypermedia relations, or OpenAPI-described relations for legacy APIs, and can return or push the related resources so a client can later fetch them from cache.
In package-nerd terms, the installed `vulcain` command is mainly useful to API and framework developers experimenting with HTTP-native API composition. It is closely associated with API Platform, Caddy, OpenAPI, and the broader debate over when GraphQL-style query layers are necessary.
