Whenever I work with GraphQL I find the commonly available API documentation difficult to navigate, especially when I need to find out how to query a particular piece of information. At some point I ended up creating a schema explorer for fly.io’s API that would let me search and drill into types, but it had one major drawback: it couldn’t render union types, which are very common in GitHub’s API.
Anyways, the viewer just got an overhaul that adds support for unions and improves the handling of enums. I hope you find it useful, and please let me know if you run into any issues!
