Hello everyone, this is Prince. Today, I'll be guiding you through the process of creating a code editor using React.js. React is a powerful JavaScript library for building user interfaces, and it’s well-suited for creating dynamic and responsive web applications. Let's get started!

First, you need to set up your React environment. You can do this by using Create React App, a convenient tool to set up a new React project with a single command:

npx create-react-app code-editor
cd code-editor

Once your project is set up, you'll need to install the react-codemirror2 package, which provides a React wrapper for CodeMirror, a versatile text editor implemented in JavaScript:

npm install react-codemirror2 codemirror

Next, create a new component called CodeEditor.js. In this component, import the necessary modules and set up CodeMirror:


import React, { useState } from 'react';
import { Controlled as ControlledEditor } from "react-codemirror2"; 
import "codemirror/lib/codemirror.css"; 
import "codemirror/theme/material.css"; 
function App() { 
const [code, setCode] = useState("// Write your code here"); 
const handleCodeChange = (editor, data, value) => { setCode(value); 
} 
return ( 
<div> 
<ControlledEditor value={code} onBeforeChange={handleCodeChange} options={{ mode: "javascript", theme: "material", lineNumbers: true }} />
</div> 
); }
