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.

Browser & Runtime Support

Many of these packages need to work in multiple environments.

By default, all typescript packages target es6.

graphql-language-service-server and graphql-language-service-cli are made for the node runtime, so they target es2017

codemirror-graphql and the graphiql browser bundle use the .browserslistrc, which targets modern browsers to keep bundle size small and keep the language services performant where async/await is used, and especially to avoid the requirement of regenerator-runtime or special babel configuration.
