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 3: Connecting the Database with TypeORM

In the last chapter, we learned how to set up a Node.js server with GraphQL support to implement a backend application. Additionally, we explained how to install Express.js and configure it with TypeScript and GraphQL. We used mocking to provide a working GraphQL server with Apollo Server before implementing the resolvers that should actually be responsible for fetching and adding data.

In addition, we set up Cross-Origin Resource Sharing (CORS) and used Apollo Studio to communicate with our GraphQL server.

In this chapter, we'll look at how to connect a MySQL database to our application using TypeORM, as well as how to create resolvers to get and save data from the database.

Now that we've built a backend application that can respond to GraphQL queries, we'll need to connect it to our database in order to store our data. We'll utilize TypeORM to abstract the database operations, allowing you to use any desired...
