GraphiQL is a free, interactive, in-browser IDE for GraphQL. Its editor supports the latest GraphQL specification, with syntax highlighting, type-aware suggestions, query and variable completion, and real-time error highlighting. A searchable documentation explorer can display Markdown, and the built-in query history and documentation explorer are available as plugins. GraphiQL can preserve state in browser localStorage and provides a plugin API for extending its interface. It is also a React package for embedding the IDE in an application; a component needs a fetcher function that sends requests to a GraphQL API. The toolkit fetcher supports HTTP, multipart incremental delivery, and subscriptions through graphql-ws or the legacy WebSocket protocol. Developers can customize the interface with React props and children, while CSS variables are the supported way to change its appearance. GraphiQL is open source under the MIT license. Its project offers a progressive web app demo and examples for CDN, Webpack, Create React App, and Parcel.
