React constitutes an avant-garde library that employs an evolved component-based approach for constructing web applications. It is pertinent to note that while React constructs applications using the “create react app” command, TypeScript enables the development of applications using React and TypeScript together.
Are you looking for a step-by-step walkthrough for building a React app with TypeScript? If yes, here we go. This article discusses the easy steps to set up a React Typescript application and highlights the prerequisites for building a React App with Typescript.
Before jumping on the process of building a React App with TypeScript, you should first take note of the various prerequisites. These are:
Before diving into building a React App with TypeScript, it is essential to have a basic understanding of React itself. Familiarity with React's core concepts, such as components, state, and props, will provide a solid foundation for working with TypeScript.
The official documentation of React includes a dedicated section on TypeScript. It provides detailed explanations, examples, and best practices for integrating TypeScript into React projects. Going through this section can greatly help in understanding how to leverage TypeScript's features effectively while working with React.
Follow the comprehensive set of steps given below to create a React Typescript application:
"npx create-react-app App –template TypeScript."
‘’npx create-react-app@latest my-ts-app --template typescript’’
"lib": ["dom," "dom.iterable", "esnext"],
You can face a wide range of assorted error codes at this stage. However, there is no need to fret. Consider employing type assertion to eliminate the error in index.tsx. Soon after setting up the React application, it is your turn to run it. You can also test it by entering the following command:
‘’npm start #or yarn start’’
Furthermore, Typescript also supports existing projects in React. All you have to do is to employ the below:
‘’npm install --save typescript @types/node @types/react @types/react-dom @types/jest’’
These accolades make Typescript the first preference of professionals when it comes to React.
There are different steps for declaring state and props in the functional and class-based components.
Props types in the functional component can be declared by employing 'React.FC', a general type function used to apprise the Typescript of the information that the current function reverts to JSX. Notably, the component constitutes the below-mentioned props:
The procedure in a class component is similar. The only difference lies in the process of the creation of the props. Herein, it would help if you carried over the prop and state types as generic to React.
The steps to integrate Typescript in a pre-existing app are as follows:
‘’npm install --save typescript @types/node @types/react @types/react-
In such a case, npx employs a cached version of create react app. You are required to remove any previously installed versions by using the command "npm uninstall -g create-react-app." You can alternatively use the command "yarn global remove create-react-app."
