GraphiQL is the reference implementation of this monorepo, GraphQL IDE, an official project under the GraphQL Foundation. The code uses the permissive MIT license.

Whether you want a simple GraphiQL IDE instance for your server, or a more advanced web or desktop GraphQL IDE experience for your framework or plugin, or you want to build an IDE extension or plugin, you've come to the right place!

The purpose of this monorepo is to give the GraphQL Community:

  • a to-specification official language service (see: API Docs)
  • a comprehensive LSP server and CLI service for use with IDEs
  • a codemirror mode
  • a monaco mode (in the works)
  • an example of how to use this ecosystem with GraphiQL.
  • examples of how to implement or extend GraphiQL.

Fielding Proposals!

The door is open for proposals for the new GraphiQL Plugin API, and other ideas on how to make the rest of the IDE ecosystem more performant, scaleable, interoperable and extensible. Feel free to open a PR to create a document in the

directory. Eventually we hope to move these to a repo that serves this purpose.
