React, often referred to as ReactJS, is widely used for building user interfaces due to its simplicity and performance. With React, developers can break down their user interfaces into reusable components, making it easier to manage and maintain complex UI structures. React’s virtual DOM efficiently updates only the necessary parts of the UI, resulting in faster rendering and improved performance. React also has a vibrant community and extensive ecosystem, offering a wide range of third-party libraries and tools to enhance development workflows.
Next, we will guide you through the process of setting up a React application with TypeScript configuration, enabling you to start using TypeScript with React and unlock the combined benefits of these technologies.
If you’re ready to start using TS with Reactjs, the first step is to set up a new React application with TypeScript configuration. By integrating these two powerful technologies, you can take advantage of static typing and enhance the reliability and maintainability of your codebase.
To create a new React app with TypeScript, follow these steps:
First, make sure you have Node.js installed on your machine. Then, open your terminal and run the following commands to install create a React app with TypeScript:
| npx create-react-app my-app –template typescript |
After the installation is complete, navigate to the directory of your newly created React app:
| cd my-app |
To launch the development server and see your React app in action, run the following command:
| npm start |
That’s it! You have successfully set up a React app with TypeScript configuration. Now you can start building your React component using TypeScript’s static typing features and enjoy the benefits of a more reliable and maintainable codebase.
But incase if you only want to install typescript then you should follow below steps.
| npm install -g typescript |
| tsc -v |
| tsc example.ts |
| node example.js |
TypeScript installed, You’re now set up to write and execute TypeScript code!
Configuring TypeScript involves setting up a `tsconfig.json` file in your project directory to define compiler options and other settings for the TypeScript compiler. This file allows you to specify various options such as target ECMAScript version, module system, output directory, strict type checking, and more. By configuring TypeScript, you can tailor the compilation process to suit your project’s needs and ensure consistency and correctness in your codebase. The TypeScript compiler file extension uses .ts and .tsx file extensions to recognize TypeScript files.

Components are the fundamental building blocks of an application. They encapsulate the UI logic and enable reusable code, making it easier to create scalable and maintainable applications. Make all component wisely components folder. With TypeScript, we can take the development of React component to the next level by introducing strong typing.
TypeScript allows us to define strict type annotations and interfaces for our React components, ensuring that the props and state are properly typed and eliminating common errors during development. By specifying the types for component props, we can prevent potential bugs and improve code readability and maintainability.
When using TypeScript with Reactjs component, we can leverage the power of IntelliSense, which provides intelligent auto-completion and real-time error checking in popular code editors. This feature enhances productivity and reduces the time spent debugging, allowing developers to focus on building robust and efficient applications.
To illustrate the benefits of TypeScript in React component development, let’s consider a simple example where we have a Button component. With TypeScript, we can define the props of this component using interfaces, ensuring consistent and well-documented usage:
| <span class=“function”>interface ButtonProps { Â text: string; Â onClick: (event: React.MouseEvent<HTMLButtonElement, MouseEvent>>) => void; } <span class=“function”>const Button: React.FCButtonProps> = ({text, onClick}) => ( Â <span class=“tag”>button onClick={onClick}> Â Â {text} Â </button>> ); |
In the example above, the ButtonProps interface defines two properties: text of type string and onClick of type React.MouseEvent. This ensures that any component using this Button component follows the expected prop types.
By utilizing TypeScript’s type checking capabilities, we minimize the chances of passing incorrect props or mismatching types, resulting in more reliable and bug-free Reactjs components.
TypeScript empowers React developers to create better components with type annotations and interfaces. This leads to improved code quality, enhanced productivity, and a more maintainable codebase. With TS and React, you can build robust and scalable applications while enjoying the benefits of strong typing.
Managing state effectively is crucial for building robust and scalable applications. Thankfully, React hooks provide a powerful solution for state management in functional components. By combining TypeScript with React hooks, you can ensure type safety and enhance the overall development experience.
When using TypeScript with React hooks, you can define the types of your state variables, ensuring that only valid values are assigned. This helps prevent common programming errors and enhances the reliability of your codebase. By providing type annotations for your state variables, you can also improve code readability and facilitate debugging. When integrating TypeScript with React, the “user object” can be utilized to manage user authentication and authorization within the application, ensuring secure access to different features and personalized experiences for users.
For example, let’s say you have a functional component that needs to manage a boolean value:
| import React, { useState } from ‘react’; function ExampleComponent() {  const [isActive, setIsActive] = useState(false);  // Rest of the component’s logic  // … } |
In above code example, the isActive state variable is specified as a boolean type. TypeScript will enforce that only boolean values can be assigned to this variable, preventing accidental assignments of non-boolean values.
