To get started quickly with React TextArea, you can watch this video:

Setup for local development

Easily set up a React application using create-vite-app, which provides a faster development environment, smaller bundle sizes, and optimized builds compared to traditional tools like create-react-app. For detailed steps, refer to the Vite installation instructions. Vite sets up your environment using JavaScript and optimizes your application for production.

Note: To create a React application using create-react-app, refer to this documentation for more details.

To create a new React application, run the following command.

npm create vite@latest my-app

This command will prompt you for a few settings for the new project, such as selecting a framework and a variant.

Initial_setup

To set up a React application in TypeScript environment, run the following command.

npm create vite@latest my-app -- --template react-ts
cd my-app
npm run dev

To set up a React application in JavaScript environment, run the following command.

npm create vite@latest my-app -- --template react
cd my-app
npm run dev

Adding Syncfusion® TextArea packages

All the available Essential® JS 2 packages are published in the npmjs.com public registry.
To install the TextArea component, use the following command

npm install @syncfusion/ej2-react-inputs --save

The –save will instruct NPM to include the TextArea package inside of the dependencies section of the package.json.

Adding CSS reference

The following CSS files are available in the ../node_modules/@syncfusion package folder. Add these as references in src/App.css.

@import "../node_modules/@syncfusion/ej2-base/styles/tailwind3.css";
@import "../node_modules/@syncfusion/ej2-react-inputs/styles/tailwind3.css";

To refer App.css in the application then import it in the src/App.tsx file.

Adding TextArea component

The React TextArea component can be added to the application by following these steps. To get started, add the TextArea component to the src/App.tsx file using the following code.

The following textarea code should be placed in the src/App.tsx file.

import { TextAreaComponent } from '@syncfusion/ej2-react-inputs';
import * as React from 'react';
import './App.css';

function App() {
  return (
    <TextAreaComponent id='default'></TextAreaComponent>
  );
}
export default App;

Run the application

Run the npm run dev command in the terminal to start the development server. This command compiles your code and serves the application locally, opening it in the browser.

npm run dev

The output appears as follows.

// Import the TextArea.
import { TextAreaComponent } from '@syncfusion/ej2-react-inputs';
import * as React from 'react';
import * as ReactDom from 'react-dom';
// To render TextArea.
function App() {
    return (<div className='wrap'>
            <TextAreaComponent id='default'></TextAreaComponent>
        </div>);
}
export default App;
ReactDom.render(<App />, document.getElementById('input-container'));
// Import the TextArea.
import { TextAreaComponent } from '@syncfusion/ej2-react-inputs';
import * as React from 'react';
import * as ReactDom from 'react-dom';

// To render TextArea.
function App() {
  
    return (
        <div className='wrap'>
            <TextAreaComponent id='default'></TextAreaComponent>
        </div>
    );
}
export default App;
ReactDom.render(<App />,document.getElementById('input-container'));

Getting and setting values

To set the initial value of the TextArea component, use the value property. Here’s how you can achieve it:

import { TextAreaComponent } from '@syncfusion/ej2-react-inputs';
import * as React from 'react';
import './App.css';

function App() {
  return (
    <div className='wrap'>
      <TextAreaComponent id='default' value='Comments'></TextAreaComponent>
    </div>
  );
}
export default App;
  • Alternatively, set the value of the TextArea using a state variable.
import { TextAreaComponent } from '@syncfusion/ej2-react-inputs';
import { useState } from 'react';
import * as React from 'react';
import './App.css';

function App() {
  // Declare state variable textValue and a function setTextValue to update it.
  const [textValue, setTextValue] = useState("comments");
  return (
    <div className='wrap'>
      <TextAreaComponent id='default' value={textValue}></TextAreaComponent>
    </div>
  );
}
export default App;
  • Dynamically retrieve the value of the TextArea component using the state variable assigned to the value property.
import { TextAreaComponent } from '@syncfusion/ej2-react-inputs';
import { useState } from 'react';
import * as React from 'react';
import './App.css';

function App() {
  const [textValue, setTextValue] = useState("comments");
  function onButtonClick() {
    // Get the value of the TextArea using state variable.
    let value = textValue;
  }
  return (
    <div className='wrap'>
      <TextAreaComponent id='default' value={textValue}></TextAreaComponent>
      <button id="valuebtn" onClick={onButtonClick.bind(this)}>Get Value</button>
    </div>
  );
}
export default App;
  • Retrieve the value of the TextArea by accessing it from the change event arguments.
import { TextAreaComponent } from '@syncfusion/ej2-react-inputs';
import type { ChangedEventArgs } from '@syncfusion/ej2-react-inputs';
import * as React from 'react';
import './App.css';

function App() {
  // triggers when the content of TextArea has changed and gets focus-out.
  function change(args: ChangedEventArgs) {
    // Get the value of the TextArea from event arguments.
    let value = args.value;
  }
  return (
    <div className='wrap'>
      <TextAreaComponent id='default' value='Comments' change={change}></TextAreaComponent>
    </div>
  );
}
export default App;
