    Apollo Server has a large and active community, providing extensive documentation, tutorials, and third-party tools. This support can be invaluable for developers looking to implement complex features or troubleshoot issues.

Performance

  • graphql:

    Performance depends on the implementation of the GraphQL server. Developers have full control over how to optimize data fetching and processing, but this requires a deeper understanding of performance best practices.

  • graphql-yoga:

    GraphQL Yoga is designed for performance and scalability, offering built-in features for handling subscriptions and real-time data. It is suitable for applications that expect high traffic and require efficient data handling.

  • express-graphql:

    Express-GraphQL is lightweight and can perform well for small to medium-sized applications. However, it may require additional optimization techniques for larger applications, as it does not come with built-in performance enhancements like Apollo Server.

  • apollo-server:

    Apollo Server is optimized for performance with features like caching and batching, which can significantly reduce the number of requests made to the server. It also provides tools for monitoring performance and tracing queries, helping developers optimize their APIs.

Learning Curve

  • graphql:

    Learning GraphQL itself can be straightforward, but implementing a server requires understanding both the specification and the chosen library's features. This can present a steeper learning curve for beginners.

  • graphql-yoga:

    GraphQL Yoga is designed to be beginner-friendly, with a focus on simplicity and ease of use. Its sensible defaults and comprehensive documentation make it an excellent choice for developers new to GraphQL.

  • express-graphql:

    Express-GraphQL has a gentle learning curve, especially for those already familiar with Express.js. Its simplicity allows developers to quickly grasp the basics of GraphQL and start building APIs without much overhead.

  • apollo-server:

    Apollo Server has a moderate learning curve, especially for developers new to GraphQL. However, its extensive documentation and community resources can help ease the learning process, making it accessible for most developers.

How to Choose: graphql vs graphql-yoga vs express-graphql vs apollo-server

Getting Started

A general overview of GraphQL is available in the README for the Specification for GraphQL. That overview describes a simple set of GraphQL examples that exist as tests in this repository. A good way to get started with this repository is to walk through that README and the corresponding tests in parallel.

Using GraphQL.js

Install GraphQL.js from npm

With npm:

npm install --save graphql

or using yarn:

yarn add graphql

GraphQL.js provides two important capabilities: building a type schema and serving queries against that type schema.

First, build a GraphQL type schema which maps to your codebase.

import {
  graphql,
  GraphQLSchema,
  GraphQLObjectType,
  GraphQLString,
} from 'graphql';

var schema = new GraphQLSchema({
  query: new GraphQLObjectType({
    name: 'RootQueryType',
    fields: {
      hello: {
        type: GraphQLString,
        resolve() {
          return 'world';
        },
      },
    },
  }),
});

This defines a simple schema, with one type and one field, that resolves to a fixed value. The resolve function can return a value, a promise, or an array of promises. A more complex example is included in the top-level tests directory.

Then, serve the result of a query against that type schema.

var source = '{ hello }';

graphql({ schema, source }).then((result) => {
  // Prints
  // {
  //   data: { hello: "world" }
  // }
  console.log(result);
});

This runs a query fetching the one field defined. The graphql function will first ensure the query is syntactically and semantically valid before executing it, reporting errors otherwise.

var source = '{ BoyHowdy }';

graphql({ schema, source }).then((result) => {
  // Prints
  // {
  //   errors: [
  //     { message: 'Cannot query field BoyHowdy on RootQueryType',
  //       locations: [ { line: 1, column: 3 } ] }
  //   ]
  // }
  console.log(result);
});

Note: Please don't forget to set NODE_ENV=production if you are running a production server. It will disable some checks that can be useful during development but will significantly improve performance.

Want to ride the bleeding edge?

The npm branch in this repository is automatically maintained to be the last commit to main to pass all tests, in the same form found on npm. It is recommended to use builds deployed to npm for many reasons, but if you want to use the latest not-yet-released version of graphql-js, you can do so by depending directly on this branch:

npm install graphql@git://github.com/graphql/graphql-js.git#npm

Experimental features

Each release of GraphQL.js will be accompanied by an experimental release containing support for the @defer and @stream directive proposal. We are hoping to get community feedback on these releases before the proposal is accepted into the GraphQL specification. You can use this experimental release of GraphQL.js by adding the following to your project's package.json file.

"graphql": "experimental-stream-defer"

Community feedback on this experimental release is much appreciated and can be provided on the issue created for this purpose.

Using in a Browser

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!
