When building a GraphQL server, one of the first decisions you must make is which GraphQL implementation to use. There are three popular options.

1. GraphQL.js — This is the reference implementation for GraphQL. GraphQL schemas are built by composing objects created from classes such as GraphQLObjectType, GraphQLInterfaceType, and GraphQLEnumType.
2. TypeGraphQL — This implementation builds upon the reference implementation and adds built-in TypeScript support. It makes it easier to make schemas typesafe. GraphQL schemas are built by creating classes and decorating them and their methods with TypeGraphQL decorators.
3. GraphQL Nexus — Similarly to TypeGraphQL, this implementation builds upon the reference implementation and adds built-in TypeScript support. However, the approach taken is much different. Similarly to the reference implementation, GraphQL schemas are created by composing objects created from classes such as objectType, interfaceType, and enumType. Unlike the reference implementation, Nexus uses some black magic TypeScript trickery so that your schemas are more strongly typed. Unfortunately, as we’ll see below, this doesn’t always work so well.

In order to do a proper comparison of these three implementations, I’ll show how you can build the  Star Wars schema using each of them and talk about their pros and cons. At the end, I’ll give my opinion on which one I prefer using.

The essential JavaScript concepts that you should understand - For successful developing and to pass a work interview

Learn how to build your GraphQL client in JavaScript. Learn about GraphQL and how to use it with MongoDB. GraphQL was designed to address several known flaws with RESTful APIs. What is the philosophy behind GraphQL? How do you architect a scalable schema? How can GraphQL boost productivity?

JavaScript data types are kept easy. While JavaScript data types are mostly similar to other programming languages; some of its data types can be unique. Here, we’ll outline the data types of JavaScript.

The API I wish JavaScript GraphQL implementations supported - The GraphQL schema language is great! It is certainly the best way to communicate anything about a GraphQL service. No wonder all documentations now use it!
