GraphQL: Learn Basic GraphQL with Node JS and MongoDB

You will learn the following things in the course:

Learn GraphQL API with Apollo Server in Node.js, Express, and MongoDB.

More and more teams are choosing GraphQL instead of (or along with) REST for their web APIs. GraphQL queries give clients great flexibility in the way they request data from the server, preventing issues such as fetching or under fetching of data, and allowing multiple resources to be retrieved in a single request.

In this course, you’ll learn how to use GraphQL both on the server–side and in client applications through practical examples in the form of full–stack JavaScript applications. You will be introduced to all the main GraphQL concepts like schema definition, Queries, Mutations, and Subscriptions, as well as to solutions to common requirements such as handling authentication/authorization and client–side caching.

The examples use Apollo Server with Node.js and Express on the backend and Apollo Client with React on the frontend. The aim however is not just to cover specific GraphQL libraries, but to give you a more general understanding of the underlying concepts. For instance, Apollo Client is only introduced after learning how to write a simple client by hand to make sure you understand GraphQL over HTTP format.
