Gain insights into integrating TypeScript with React to improve productivity. Learn about strongly-typed props, state, and events, and set up projects using Create React App, Webpack, and Babel.

If you are a React developer and want to build your React apps faster and more robustly, this course is for you. Learn to integrate TypeScript with React, boost your productivity, and create apps that are easier to maintain.

In this course, you will learn how to utilize TypeScript’s sophisticated type system to make React development faster and your code more readable. You will learn how to create component props, state, and events that are strongly-typed, allowing you to quickly understand what you can pass and helping you avoid mistakes.

Lastly, you will set up React projects with TypeScript. First, you will learn how to do this with the Create React App tool, then how to create a React and TypeScript project with Webpack and Babel.

Using TypeScript with React

# Technical requirements

We are going to use the following tools in this lesson:
* **Node.js** and **npm**. These can be installed from [https://nodejs.org/en/download/](https://nodejs.org/en/download/). **npm** needs to be at least at version 5.2.
* A code editor such as **Visual Studio Code**. Visual Studio Code can be installed from [https://code.visualstudio.com/](https://code.visualstudio.com/)

# Introducing Create React App

[**Create React App**](https://create-react-app.dev) (CRA) is a command-line tool built by the developers at Facebook to help us quickly build React applications. It sets up many useful dependencies for us and has the option to create a React project with TypeScript.

In this lesson, we will create a new React and TypeScript project using the popular Create React App tool.
