Full-Stack Angular 11 and GraphQL Book

PART 1: Setup Development Environment, GraphQL Server and Database

In this part, we’ll learn about our app’s architecture and requirements and we’ll set up our development environment for full-stack Angular 11 development. We’ll also set up a GraphQL server with Express.js and Apollo and connect a SQL database for storing the application data using TypeORM.

CHAPTER 1: App Architecture and Development Environment

Throughout this book, we’ll build a full-stack web application with an Angular 11 front-end and a Node.js back-end so in this chapter, we'll first learn about the structure and the tools we need to build the app. Next, we'll prepare our machine for Angular, MySQL and Node.js development and initialize a new project based on the latest version of Angular. Finally, we’ll introduce you to debugging with the latest Angular’s Ivy runtime which will help you view and update your application state in DevTools.

After setting up the development environment, installing Node.js, and initializing the Angular front-end project using the CLI, we'll next need to set up a Node.js server with GraphQL support to implement the back-end. In this chapter, we'll explain how to install Express.js and configure it with TypeScript and GraphQL. We’ll add routing, static assets and cors. Finally, we'll learn how to test our GraphQL server and debug it using Postman, GraphiQL and Apollo DevTools..

CHAPTER 3: Connecting the Database with TypeORM

Now that we have a back-end ready that can respond to GraphQL queries and a front-end project. We'll need to connect our database to store our data. We'll be using TypeORM for abstracting the database operations which allows you to use any prefered database management system for your app without changing the code. We’ll see how to integrate TypeORM with Apollo and then migrate and seed our database.

Main Chapter Headings

  1. Using a database with GraphQL
  2. Using TypeORM with Node.js

  3. Create database models for TypeORM
  4. Integrate TypeORM with Apollo
  5. Migrate the database

PART 2: Build the Angular Front-End with Realtime Support

In the previous part we have prepared both the development environment for Angular and created a GraphQL server with Express.js and Apollo. In this part, we’ll implement the front-end of our application using Angular and Apollo. We’ll add routing and navigation between various modules and components then we’ll finally implement real-time support using GraphQL subscriptions.

CHAPTER 4: Angular Application Architecture and Routing

In the previous chapters we created the front-end project using Angular CLI. In this chapter, we'll use Angular CLI to create the modules, services and components that compose the UI of our application. Angular allows us to create the front-end of our backend with a modular and component based architecture.

After creating the various artifacts needed in our app such as modules, services and components, we’ll introduce Angular routing and we’ll proceed to implement routing and navigation in our application to create a single page application.

Main Chapter Headings

  1. Understanding the Application Architecture with Modules, and Components
  2. Services and Dependency Injection
  3. Creating Modules and Components
  4. Understanding Angular Routing
  5. Adding Routes
  6. Adding Navigation

Skills learned

  1. Understand Angular Architecture
  2. Understand Services and Dependency Injection
  3. Use Angular CLI to create modules, services, and components
  4. Understand Angular routing
  5. Add routes to different views
  6. Add navigation in the app

CHAPTER 5: Integrating the Angular Front-End with the GraphQL Back-End

Angular allows us to create the front-end of our backend with a modular and component based architecture. In this chapter, we'll learn how to use the Apollo client to connect the front-end with the GraphQL backend.
