Apollo Federation

Apollo Federation is an architecture for declaratively composing APIs into a unified graph. Each team can own their slice of the graph independently, empowering them to deliver autonomously and incrementally.

Federation 2 is an evolution of the original Apollo Federation with an improved shared ownership model, enhanced type merging, and cleaner syntax for a smoother developer experience. It’s backwards compatible, requiring no major changes to your subgraphs.

Checkout the Federation 2 docs and demo repo to take it for a spin and let us know what you think!

Usage

This crate is internal to Apollo Router and not intended to be used directly.

Crate versioning

The apollo-federation crate does not adhere to Semantic Versioning. Any version may have breaking API changes, as this API is expected to only be used by apollo-router. Instead, the version number matches exactly that of the apollo-router crate version using it.

This version number is not that of the Apollo Federation specification being implemented. See Router documentation for which Federation versions are supported by which Router versions.
