📎 GraphQL support

[ematipico]

Description

Our most-upvoted request in the discussion is support for linting of GraphQL files. Unfortunately, GraphQL support is not part of our roadmap for 2024. This means the Biome team will be unlikely to pick up this task as we are busy working on other parts of the roadmap. Still, we would like to facilitate GraphQL support if someone is willing to pick up the work.

What is included in this task

• A parser for GraphQL
• At least one lint rule for GraphQL to demonstrate the analyzer
• Support for *.graphql files in the VS Code extension

What is not included in this task

• GraphQL tagged templates
  • Support for tagged templates requires infrastructure that is still being worked on in Biome. We are expected to develop support for tagged templates for CSS use cases such as styled components. Once this is in place, and this GraphQL task is implemented, hopefully GraphQL tagged templates will be easy to implement as well.

I have raised a PR for implementing GraphQL grammar here #1949

I removed the formatter from the plan to ship GraphQL. Implementing a formatter isn't an easy task.

This could change in the future if we will be able to secure more funding for the people that are working on this task.

For anyone subscribed to the issue, we enabled GraphQL support on the playground: https://biomejs.dev/playground/?files.main.gql=dAB5AHAAZQAgAFEAdQBlAHIAeQAgAHsACgAgACAAbQBlADoAIABVAHMAZQByAAoAfQAKACAACgB0AHkAcABlACAAVQBzAGUAcgAgAHsACgAgACAAaQBkADoAIABJAEQACgAgACAAbgBhAG0AZQA6ACAAUwB0AHIAaQBuAGcACgB9AA%3D%3D

Feedback is very welcome!

Not 100% sure of the feedback needed, but I've tested a few documents and schema I have here and it parses without issues ...
It looks promising 👏

Note prettier panel isn't configured for gql right?

No, as for now only parsing is supported.
