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

# Installing Webpack

[**Webpack**](https://webpack.js.org/) is a popular tool that we can use to bundle all our JavaScript code into the `bundle.js` file that our `index.html` is expecting. Let's install the core webpack library as well as its command-line interface:

```shell
npm install --save-dev webpack webpack-cli
```

TypeScript types are included in the `webpack` package, so we don't need to install them separately.

Webpack has a web server that we will use during development. Let's install this:

```shell
npm install --save-dev webpack-dev-server @types/webpack-dev-server
```

TypeScript types aren't included in the `webpack-dev-server` package, which is why we installed the `@types/webpack-dev-server` package.

Why do you think we installed these Webpack dependencies as development dependencies?

We only use Webpack at development time to do our build and also as a development web server.

# Installing Webpack Babel and ESLint plugins

We need a webpack plugin, `babel-loader`, to allow Babel to transpile the React and TypeScript code into JavaScript. Let's install this:

```shell
npm install --save-dev babel-loader
```



In this lesson, we'll continue to set up our React and TypeScript project by adding a tool that will bundle the code together.
