You’ll use it to quickly set up a CRUD (Create, Read, Update, and Delete) backend. You will build the backend using a fake REST API named json-server. In this tutorial, you will create a customer list management application with a separate REST API backend and a frontend built with React and TypeScript. The great performance and dynamic user interfaces built with React for single-page applications make it a popular choice among developers. React is an open-source JavaScript library, which developers use to create high-end user interfaces for scalable web applications. One of the major benefits of using a statically typed programming language is that type checking is completed at compile time, therefore developers can see errors in their code at a very early stage. Statically typed programming languages like TypeScript enforce an association for every variable with a data type such as a string, integer, boolean, and so on. To achieve this, writing statically typed code is a style adopted by many seasoned developers. One of the ways to improve productivity as a developer is the ability to implement new features as quickly as possible without any concern over breaking the existing app in production. The Nest.js back-end framework was also built with TypeScript. TypeScript is increasingly gaining popularity adopted by major companies like Google for the Angular web framework. Defined as a superset of JavaScript, TypeScript behaves identically to JavaScript but with extra features designed to help developers build larger and more complex programs with fewer or no bugs. TypeScript has brought a lot of improvement into how JavaScript developers structure and write code for apps, especially web applications.
