GraphQL.js

The JavaScript reference implementation for GraphQL, a query language for APIs created by Facebook. GraphQL.js is a general-purpose library and can be used both in a Node server and in the browser. As an example, the GraphiQL tool is built with GraphQL.js! Building a project using GraphQL.js with webpack or rollup should just work and only include the portions of the library you use. This works because GraphQL.js is distributed with both CommonJS (require()) and ESModule (import) files. Ensure that any custom build configurations look for .mjs files! For practical applications, you'll probably want to run GraphQL queries from an API server, rather than executing GraphQL with a command line tool. GraphQL.js provides two important capabilities: building a type schema and serving queries against that type schema.
