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® MaskedTextBox packages

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

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

The –save will instruct NPM to include the MaskedTextBox 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 MaskedTextBox component

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

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

[Class-component]

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

export default class App extends React.Component<{}, {}> {
  public render() {
    return (
      <MaskedTextBoxComponent placeholder="Enter Name"></MaskedTextBoxComponent>
    );
  }
};

[Functional-component]

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

export default function App() {
  return (
    <MaskedTextBoxComponent placeholder="Enter Name"></MaskedTextBoxComponent>
  );
};

Set the Mask

Set the input mask using the mask property to validate user input. For details about mask tokens and configuration, see the mask configuration guide at mask-configuration.

The following example demonstrates the 0 mask token, which requires a single digit from 0 to 9 for each position.

[Class-component]

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

export default class App extends React.Component<{}, {}> {
  public render() {
    return (
      <MaskedTextBoxComponent mask={'000-000-0000'}></MaskedTextBoxComponent>
    );
  }
};

[Functional-component]

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

export default function App() {
  return (
    <MaskedTextBoxComponent mask={'000-000-0000'}></MaskedTextBoxComponent>
  );
};

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.

[Class-component]

import { MaskedTextBoxComponent } from '@syncfusion/ej2-react-inputs';
import * as React from "react";
import * as ReactDOM from "react-dom";
// initializes MaskedTextBox component
// sets value to the MaskedTextBox
export default class App extends React.Component {
    render() {
        return (<div>
            <label className='label'>Enter the mobile number</label>
            <MaskedTextBoxComponent mask={'000-000-0000'}/>
          </div>);
    }
}
;
ReactDOM.render(<App />, document.getElementById('maskedContainer'));
import { MaskedTextBoxComponent } from '@syncfusion/ej2-react-inputs';
import * as React from "react";
import * as ReactDOM from "react-dom";

// initializes MaskedTextBox component
// sets value to the MaskedTextBox
export default class App extends React.Component<{}, {}> {
    public render() {
        return (
          <div>
            <label className='label'>Enter the mobile number</label>
            <MaskedTextBoxComponent mask={'000-000-0000'} />
          </div>
        );
    }
};
ReactDOM.render(<App />, document.getElementById('maskedContainer'));

[Functional-component]

import { MaskedTextBoxComponent } from '@syncfusion/ej2-react-inputs';
import * as React from 'react';
import * as ReactDOM from 'react-dom';
// initializes MaskedTextBox component
// sets value to the MaskedTextBox
function App() {
    return (<div>
      <label className="label">Enter the mobile number</label>
      <MaskedTextBoxComponent mask={'000-000-0000'}/>
    </div>);
}
ReactDOM.render(<App />, document.getElementById('maskedContainer'));
import { MaskedTextBoxComponent } from '@syncfusion/ej2-react-inputs';
import * as React from 'react';
import * as ReactDOM from 'react-dom';

// initializes MaskedTextBox component
// sets value to the MaskedTextBox
function App() {
  return (
    <div>
      <label className="label">Enter the mobile number</label>
      <MaskedTextBoxComponent mask={'000-000-0000'} />
    </div>
  );
}
ReactDOM.render(<App />, document.getElementById('maskedContainer'));
