How to create a simple component in React
React is a popular JavaScript library for building user interfaces. It is used by many companies and developers to create interactive web applications. In this tutorial, we will learn how to create a simple component in React.
Install React
The first step in creating a React component is to install React. You can do this by using the Node Package Manager (NPM). To install React, open a terminal window and type the following command:
npm install reactThis will install the latest version of React.
Create a Component
Once React is installed, you can create a component. A component is a piece of code that can be reused in different parts of your application. To create a component, create a new file in your project directory and name it
MyComponent.js.In the file, add the following code:
import React from 'react';const MyComponent = () => { return (
My Component
);};export default MyComponent;This code creates a React component called
MyComponent. The component returns a
div element with a
h1 element inside it.
Render the Component
Once you have created the component, you can render it in your application. To do this, open the file where you want to render the component and add the following code:
import React from 'react';import ReactDOM from 'react-dom';import MyComponent from './MyComponent';ReactDOM.render(, document.getElementById('root'));This code imports the
MyComponent component and renders it in the element with the
id of
root.
Test the Component
Once you have rendered the component, you can test it to make sure it is working correctly. To do this, open the browser and navigate to the page where you have rendered the component. You should see the
My Component text displayed on the page.
Conclusion
In this tutorial, we have learned how to create a simple component in React. We have installed React, created a component, rendered the component, and tested the component. With these steps, you can create your own components and use them in your React applications.
