Creating Angular Applications with GraphQL

Topic: Web Platform
Tamas Piros

Just as Angular has transformed the way developers build web applications via an opinionated way, GraphQL is an emerging technology that changes how they build APIs to query and mutate data. With GraphQL developers can query the exact data required by a page, or an application, and therefore it does not load an excessive amount of data. GraphQL can be used in any web or mobile application. In this training, you will get up and running with GraphQL and discover the core knowledge needed to create an application using Angular and GraphQL. (Please note that throughout this workshop we’ll be using Angular Apollo and Apollo GraphQL, as well as Angular version 8)

What you'll learn-and how you can apply it

By the end of this live, hands-on, online course, you’ll understand how to:

  • Implement a more advanced application that uses Angular 8 to work with GraphQL.
  • Think about your applications data in terms of a graph structure.
  • Utilise media optimisation via GraphQL.

And you’ll be able to:

  • Run GraphQL queries in an Angular context
  • Create custom types for GraphQL
  • Manage media via a third-party service and GraphQL

This training course is for you because...

  • You’re a front-end or developer who wants to apply GraphQL concepts to an Angular App.
  • You are a web developer, who already works with Angular, and are new to GraphQL.
  • You’d like to know how to remove excessive data from your application.
  • Interested in how to specify the exact data structure to be returned from an API.

Prerequisites

  • Basic Angular knowledge (components, routing, TypeScript)
  • Basic understanding of API design (RESTful APIs)
  • Basic GraphQL understanding (Queries, DataTypes, Basic Mutations)
