GraphQL Code Generator is a tool that generates code out of your GraphQL schema. Whether you are developing a frontend or backend, you can utilize GraphQL Code Generator to generate output from your GraphQL Schema and GraphQL Documents (query/mutation/subscription/fragment).
By analyzing the schema and documents and parsing it, GraphQL Code Generator can output code at a wide variety of formats, based on pre-defined templates or based on custom user-defined ones. Regardless of the language that you're using, GraphQL Code Generator has you covered.
GraphQL Code Generator lets you choose the output that you need, based on plugins, which are very flexible and customizable. You can also write your plugins to generate custom outputs that match your needs.
You can try this tool live on your browser and see some useful examples. Check out GraphQL Code Generator Live Examples.
We currently support and maintain these plugins (TypeScript, Flow, React, Angular, MongoDB, Stencil, Reason, and some more), and there is an active community that writes and maintains custom plugins.
