Create a Component.

Let’s start with the first step.

Step 1: Install and create a new React app.

First you have to install the React project. You should use create-react-app command to create a new React project.

npx create-react-app my-app
cd my-app
npm start

Step 2: Import react component.

After installing, you have to import your React component. To do this, add the following ./MaxLengthInput' to the top of your component file.

import React from 'react';
import MaxLengthInput from './MaxLengthInput';

Step 3: Create a Component.

You can use maxLength={10} to add max length in react js.

<div>
    <input
        type="text"
        value={inputValue}
        onChange={handleChange}
        maxLength={10} // Set the maximum length to 10 characters
        placeholder="Type here..."
    />
      <p>{inputValue.length} / 10</p> {/* Show the character count */}
</div>

Add max length example.

The below code is an example of a React. You have to import ./MaxLengthInput and set maxLength={10} to add max length in react js.

App.js

import React from 'react';
import MaxLengthInput from './MaxLengthInput';

function App() {
  return (
    <div className="App">
      <MaxLengthInput />
    </div>
  );
}

export default App;

MaxLengthInput.js

import React, { useState } from 'react';

const MaxLengthInput = () => {
  const [inputValue, setInputValue] = useState('');

  const handleChange = (e) => {
    setInputValue(e.target.value);
  };

  return (
    <div>
      <input
        type="text"
        value={inputValue}
        onChange={handleChange}
        maxLength={10} // Set the maximum length to 10 characters
        placeholder="Type here..."
      />
      <p>{inputValue.length} / 10</p> {/* Show the character count */}
    </div>
  );
};

export default MaxLengthInput;

In the above code example, I have used the maxLength={10} to add max length in react js.

Check the output of the above code.

All the best 👍
