Experience Benefits of Developing Apps with ReactJS & TypeScript
Getting Started with ReactJS and TypeScript
ReactJS has quickly become one of the most popular JavaScript libraries for building user interfaces. While it offers a lot of flexibility and easy-to-use features, React also requires a bit of work to get set up correctly. The use of TypeScript introduces an additional layer of complexity and a steep learning curve. In this tutorial, we’ll walk through how to set up a basic project with React and TypeScript.
Installing Dependencies
The first thing we’ll need to do is to install the required packages for our React project. We’ll be using the popular create-react-app tool to set up our project. We’ll also need to install the typescript package as well as the type-checker for React. To install these packages, open up a terminal window and run the following commands: ``` npx create-react-app my-project --typescript cd my-project npm install --save-dev typescript @types/react @types/react-dom ```
Configuring TypeScript
Once the packages have been installed, we need to configure TypeScript. We’ll be using the tsconfig.json file for this. Create the file in the root of your project and add the following to it: ``` { "compilerOptions": { "jsx": "react", "target": "ES6", "lib": ["dom", "es2015"], "allowJs": true, "skipLibCheck": true } } ``` This configuration tells the TypeScript compiler to accept both JavaScript and TypeScript code, as well as which version of JavaScript it should use.
Writing Code with React and TypeScript
Now that everything is set up it’s time to start writing some code. We’ll start by taking a look at a basic React component written in TypeScript. ``` import * as React from 'react'; type Props = { message: string; }; const HelloWorld: React.FC = ({ message }) => { return
{message}
; }; export default HelloWorld; ``` In the above example, we’ve defined a React component called HelloWorld that takes a single props called message and renders out an
