Introduction to Typescript With React: The Most Informative Guide

Many developers these days use React and TypeScript, which are two prominent technologies. TypeScript is a typed JavaScript superset that compiles to plain JavaScript. React is a user interface design library written in JavaScript. By integrating them, you basically employ a typed version of JavaScript to generate our UIs. This tutorial will give you an idea of how to use TypeScript in React projects. You'll also learn why TypeScript is useful in React, as well as how to install and set up it.

What Is TypeScript?

  • TypeScript is an object-oriented and tightly typed programming language that is a superset of JavaScript. Code written in TypeScript is converted to JavaScript, which may be utilized in any environment that supports JavaScript, such as browsers, Node.js, and your own apps.
  • Anders Hejlsberg designed typeScript at MICROSOFT. The typeScript was developed in response to JavaScript's constraints in building large-scale applications within Microsoft and among its external customers. Due to the difficulty of dealing with complicated JavaScript code, there was a need for customized tooling to make writing JavaScript components easier.
  • TypeScript is a JavaScript version with a few extra features. To provide a more robust interface with your editor, TypeScript extends JavaScript with additional syntax. TypeScript is a scripting language that understands JavaScript and uses type inference to provide advanced capabilities without having to write any more code.

What Is React?

  • React was first open-sourced in 2013 by Facebook and has since become one of the most popular libraries in the frontend world. With frameworks like Redux, React can simply be extended to integrate functionality like routing and state management patterns.
  • React is a JavaScript library for constructing declarative, efficient, and configurable user interfaces. It allows building complicated user interfaces out of "components," which are small, independent pieces of code. 

Features of React

  • React is a powerful JavaScript library that makes it easy to create interactive user interfaces. 
  • It is an open-source library and was developed by Facebook.  
  • React also has a robust, rapidly growing developer community and can be used as a base while creating single-page web and mobile apps. 
  • React apps are fast, flexible, modular, and scalable.
  • React is declarative. Declarative views make your code more predictable and easier to debug 
  • It is component-based and lets you build encapsulated components that manage their state and compose them to make complex UIs. 
  • React has a robust developer community and a wide variety of complimentary libraries for support.
  • Popular libraries include Redux, Material Design, and Jest.
  • Redux helps manage state in JavaScript. 
  • Redux is the most popular React library because it easily tracks the state as the application size grows.

Advantages of Using TypeScript With React

  • Typescript has a code that is easy to read and understand. The fact that TypeScript is a statically typed script is crucial. The distinction between statically and dynamically typed programming languages is when type checking occurs. Variables in static languages are type-checked.
  • Complex type definitions can be defined as interfaces in TypeScript. This is useful for using a complex type in your application, such as an object with multiple properties. This leads to more stringent checks, which minimizes the number of problems you could have created otherwise.
  • In a React project, TypeScript allows you to write HTML code directly. TypeScript delivers superior IntelliSense and code completion for JSX when used with React. JavaScript XM is abbreviated as JSX.
  • When using IDEs like Visual Studio, Visual Studio Code, Atom, Webstorm, Eclipse, and others, TypeScript comes in handy. These allow better development by improving autocomplete and snippet generation.
  • You can gradually integrate TypeScript into your existing projects. For this use situation, you can also configure the TypeScript compiler. The official TypeScript documentation includes a list of TypeScript compilers.
  • Microsoft supports TypeScript, an open-source programming language. Millions of developers all over the world enjoy and use it. This implies that if you get stuck while learning or using TypeScript, you can easily obtain help and answers on the community portal.

Installing and Configuring TypeScript and React

  • To install TypeScript using npm, run the below commands 

npm install -g typescript 

  • You need to connect TypeScript because you installed it globally and want npm to know where it is. For this, run the command 

npm link typescript

  • Once npm is finished, you can check to see if TypeScript is correctly installed:

tsc --v 

  • The version number of TypeScript installed will be displayed as a result of the above command. Create a folder to keep the application when it has been successfully installed so that you can begin working on a project.
  • Make a new directory:

mkdir typescript-react-project

  • Change to the new folder's directory:

cd typescript-react-project

  • Using this command the project can be initiated:

npm init

  • Run the following command in your terminal to install TypeScript with create-react-app:

npx create-react-app .

The command above will build a minimal folder structure for your application, as well as install all required modules and start your project.

  • Open the App.ts file and write few lines of code shown below to run the Hello Message.

import { Counter } from './Counter'

export const App = () => {

  return (

    <>

      <view style={{color:'green', textAlign: 'center'}} >

        <h1>Hello Everyone</h1>

      </view>

      <Counter />

    </>

  )

}

Output: Hello Everyone
