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

## Adding linting

We touched on linting with [**ESLint**](https://eslint.org/) when we created a project using Create React App. We are going to use ESLint in this project as well. So, let's install ESLint along with the plugins we are going to need as development dependencies:

```shell
npm install --save-dev eslint eslint-plugin-react eslint-plugin-react-hooks @typescript-eslint/parser @typescript-eslint/eslint-plugin
```

Below is an explanation of the packages that we just installed:
* `eslint`: This is the core ESLint library.
* `eslint-plugin-react`: This contains some standard linting rules for React code. 
* `eslint-plugin-react-hooks`: This contains some linting rules for React hooks code. 
* `@typescript-eslint/parser`: This allows TypeScript code to be linted.
* `@typescript-eslint/eslint-plugin`: This contains some standard linting rules for TypeScript code.

Can you remember what file we use to configure the linting rules?

We will continue to create our React and TypeScript project in this lesson by adding linting and autoformatting.

Why TypeScript?

Using basic types

Creating types

Working with generic types

Creating strongly-typed function component props

Creating strongly-typed function component state

Creating strongly-typed class components

Creating strongly-typed component events and event handlers

Creating strongly-typed context

Creating strongly-typed refs

Creating React projects with TypeScript using Create React App

Creating a React and TypeScript project manually

Putting everything together
