Overview of this book

React sets the standard for building high-performance client-side web apps. Node.js is a scalable application server that is used in thousands of websites, while GraphQL is becoming the standard way for large websites to provide data and services to their users. Together, these technologies, when reinforced with the capabilities of TypeScript, provide a cutting-edge stack for complete web application development. This book takes a hands-on approach to implementing modern web technologies and the associated methodologies for building full-stack apps. You’ll begin by gaining a strong understanding of TypeScript and how to use it to build high-quality web apps. The chapters that follow delve into client-side development with React using the new Hooks API and Redux. Next, you’ll get to grips with server-side development with Express, including authentication with Redis-based sessions and accessing databases with TypeORM. The book will then show you how to use Apollo GraphQL to build web services for your full-stack app. Later, you’ll learn how to build GraphQL schemas and integrate them with React using Hooks. Finally, you’ll focus on how to deploy your application onto an NGINX server using the AWS cloud. By the end of this book, you’ll be able to build and deploy complete high-performance web applications using React, Node, and GraphQL.

Understanding object relational mappers by using TypeORM

In this section, we'll learn what Object Relational Mapper (ORM) technology is. We'll also learn about TypeORM, one of the most popular ORM frameworks for JavaScript. ORM can make working with databases a lot easier and reduce some cognitive load for the developer.

As a programmer, you know that different programming languages have types that are incompatible. For example, JavaScript, despite the name, cannot use or even access Java types directly. In order for either language to use the types from the other, we would need to do some sort of translation. In part, this is the reason for having services such as the Web API. The Web API provides all data to callers as a string format, like JSON. This allows any caller to use the data since it can be read by any language.

Database to coding language conversion has similar type incompatibilities. So, normally after making a query that returns data, we would have to...
