This monorepo contains test suite that verifies subgraphs compatibility against Apollo Federation Subgraph Specification. This testing suite verifies various Federation features against subgraph implementation. See compatibility testing docs for details on the expected schema and the data sets as well as information about the executed tests. Test suite is packaged as NPX script and Github Action.
This repository also contains number of example subgraph implementations based on various libraries and other solutions. See latest compatibility results for a list of Apollo Federation compatibible subgraph implementations.
See CONTRIBUTING.md for general contribution guidelines and Apollo Federation Subgraph Maintainers Implementation Guide for subgraph implementation instructions. Once you've completed the implementations instructions, feel free to create a PR and we'll review it. If you have any questions please open a GitHub issue on this repository.
If you have a specific question about the testing library or code, please start a discussion in the Apollo community forums.
