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.

Adding navigation

Angular Router provides the routerLink and routerLinkActive directives, which have to be used instead of the regular href attribute in the <a> tag to create navigation links. routerLinkActive is used to mark an active link.

Open the src/app/core/components/header.component.html file and update it as follows:

<button routerLink="/feed/posts">Feed</button>
<button routerLink="/users/profile/ahmedbouchefra">My 
   profile</button>
<button routerLink="/users/login">Login</button>
<button routerLink="/users/signup">Sign up</button>

We added four navigation buttons with the routerLink directive, which holds the target path that users will be taken to after clicking the corresponding button.

This is just for testing our navigation links; we'll change this component's template later to include buttons in more appropriate places. For example,...
