How To Create React App with TypeScript

React is growing in popularity and is one of the best front-end libraries out there. It has become the library for many developers to build user interface applications. Using TypeScript to build our React app makes React app more predictable because we see a lot of errors at runtime. In this article, I will show you how to create a React application using TypeScript.

Create React App with TypeScript

What is React?

ReactJS is one of the most popular free and open-source libraries in the world. Built-in JavaScript. But it’s much easier to use than pure JavaScript. React is supported by Meta (Facebook). React can be used to build single-page web apps and mobile apps.

Why use React with TypeScript?

TypeScript is a programming language developed by Facebook. This is a strict set of JavaScript syntax. Compared to JavaScript, TypeScript is difficult to use. But once you get used to it, TypeScript will become easier and more useful for your project.

We usually use JavaScript in ReactJS projects, but sometimes we need to use TypeScript, and it depends on many things.
If the project is large, TypeScript is preferred because the code is much easier to understand. Mostly classes and examples. Because they have their own genre, for smaller tasks, you can use plain JavaScript.
TypeScript is very complex, unlike JavaScript, so if you or your team will work with TypeScript, you should understand TypeScript before starting a project.

Create a React Project with TypeScript

To build, we use a React app to deploy our react app in such a way that we don’t have to worry about all the stress of webpack and babel.
As you might have guessed, to configure the React-react app, we use the create-react-app with extra flags. We will type this in our terminal to open our application.
This command will create a response log for us so we can configure the server as usual.

npx create-react-app your-app --template typescript

Running the above command will effectively create your new app without any special settings. All files are now .ts or .tsx files.
In addition to configuring the TypeScript library, we see all the required declaration files to use TypeScript and React. The declarative text is used to define the type of text to be written. It can be seen as an interface between JavaScript and TypeScript. These files are included in the @type declaration.


This article is all you need to get started with TypeScript and React! Your application should now have new features and work perfectly in TypeScript. I hope you found this article helpful. Thanks for reading.
