GraphQL by Example

Learn GraphQL by writing full-stack JavaScript applications with Node.js, Express, Apollo Server, React, Apollo Client.

GraphQL by Example

What you’ll learn

Build a GraphQL server based on NodeJS, Express and Apollo Server
Invoke GraphQL APIs from JavaScript client applications using regular HTTP requests or Apollo Client
Handle Authentication/Authorization, Caching, and more

Requirements

Good knowledge of modern JavaScript, including ES6+ and NodeJS
Some knowledge of Express and React preferable but not strictly required

Description

More and more teams are choosing GraphQL by Example 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 overfetching or underfetching 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 solution 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 React on the frontend, with GraphQL-Request first, then Apollo Client as GraphQL clients. GraphQL-WS is used for subscriptions – GraphQL by Example.

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, GraphQL client libraries are introduced only after learning how to write a simple client “by hand”, to make sure you understand the GraphQL over HTTP format.

This course assumes good knowledge of modern JavaScript, and ideally some familiarity with Node.js/Express and React.
