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

# Generic interface syntax

We can pass types into an interface that are used within its definition like we can to a function. The syntax for a generic interface is below:

```
interface InterfaceName<T1, T2, ...> {
    ...
}
```

The members of the interface can reference the generic types passed into it.

# Generic interface example

A common use case for a generic interface is a generic form interface. This is because all forms have values, default values, validation rules, etc. but the specific fields differ from form to form.

Below is a simple generic form interface:

```
interface Form<T> {
  values: T;
}
```

We also have an interface for the fields on a contact form:

```
interface Contact {
  name: string;
  email: string;
}
```

How can we use both of these interfaces to create a strongly-typed version of the `contactForm` variable?

In this lesson, we will learn how to create generic interfaces.
