Full Stack Development with Angular and GraphQL

By: Ahmed Bouchefra

Overview of this book

GraphQL is an alternative to traditional REST technology for querying Web APIs. Together with Angular and TypeScript, it provides a tech stack option for building future-proof web applications that are robust and maintainable at any scale. This book leverages the potential of cutting-edge technologies like GraphQL and Apollo and helps Angular developers add it to their stack. Starting with introducing full-stack development, you will learn to create a monorepo project with Lerna and NPM Workspaces. You will then learn to configure Node.js-based backend using GraphQL, Express, and Apollo Server. The book will demonstrate how to build professional-looking UIs with Angular Material. It will then show you how to create Web APIs for your frontend with GraphQL. All this in a step-by-step manner. The book covers advanced topics such as local state management, reactive variables, and generating TypeScript types using the GraphQL scheme to develop a scalable codebase. By the end of this book, you'll have the skills you need to be able to build your full-stack application.

Chapter 11: Implementing GraphQL Subscriptions

In the previous chapter, we learned how to use Apollo Client to send queries and mutations to the backend API that we implemented previously to fetch paginated posts and comments, as well as create new comments and likes.

In this chapter, we'll continue building our users' profile components before learning how to add realtime support to our application. This will allow us to retrieve and display new data from the server without having to constantly refresh the app. We'll utilize GraphQL subscriptions with Apollo Client and Angular to do this.

Then, we'll configure Apollo Client for GraphQL subscriptions and show you how to get and display notifications in the application's header through a badge. GraphQL subscriptions allow the app to acquire new data from the server without having to manually refresh the app.

In this chapter, we will cover the following topics:

  • Persisting the component state...
