GraphiQL
GraphiQL is a free, interactive in-browser IDE for GraphQL.
What GraphiQL is
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 error highlighting. A searchable documentation explorer can display Markdown, and the plugin API includes documentation and query history plugins. The interface can retain state in browser localStorage. GraphiQL is also a React package for embedding the IDE in an application, where a fetcher function is required to send requests to a GraphQL API. Its toolkit fetcher supports HTTP, multipart incremental delivery, and subscriptions through graphql-ws or the legacy WebSocket protocol. React props and children can customize the UI, while CSS variables are the supported way to adjust appearance. The project offers an installable progressive web app demo and examples for CDN, Webpack, Create React App, and Parcel. It is MIT-licensed and open source. The browser bundle targets modern browsers and does not support Internet Explorer or older evergreen browser versions; class names may change between minor or patch releases.
