This section explains how to create a simple Floating Action Button and demonstrate the basic usage of the Floating Action Button component in an React environment.

Dependencies

The list of dependencies required to use the Floating Action Button component in your application is given below:

|-- @syncfusion/ej2-react-buttons
    |-- @syncfusion/ej2-react-base
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-buttons

Installation and Configuration

You can use Create-react-app to setup
the applications. To install create-react-app run the following command.

   ```bash
     npm install -g create-react-app
   ```

Start a new project using create-react-app command as follows

    ```
      create-react-app quickstart --scripts-version=react-scripts-ts
      cd quickstart
    ```
    ```
     create-react-app quickstart
     cd quickstart
    ```

‘react-scripts-ts’ is used for creating React app with typescript.

Adding Syncfusion packages

All the available Essential JS 2 packages are published in npmjs.com public registry.

To install Floating Action Button component, use the following command

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

Adding Floating Action Button Component to the Application

To include the Floating Action Button component in your application import the FabComponent from ej2-react-buttons package in App.tsx.

Add the Floating Action Button component in application as shown in below code example.

{/* Import the Floating Action Button */}.
import { FabComponent } from '@syncfusion/ej2-react-buttons';
import * as React from 'react';
import './App.css';

{/* To render Floating Action Button. */}
function App() {
    return (
        <FabComponent id='fab'></FabComponent>
    );
}
export default App;

{ /* Import the Floating Action Button */ }
import { FabComponent } from '@syncfusion/ej2-react-buttons';
import * as React from 'react';
import './App.css';
{ /* To render Floating Action Button. */ }
function App() {
    return (<FabComponent id='fab'></FabComponent>);
}
export default App;

Adding CSS reference

Import the Floating Action Button component’s required CSS references as follows in src/App.css.

@import "../node_modules/@syncfusion/ej2-base/styles/material.css";
@import "../node_modules/@syncfusion/ej2-buttons/styles/material.css";

Running the application

Run the application in the browser using the following command:

```
 npm start
```

The following example shows a basic Floating Action Button component.

app.jsx

import { enableRipple } from '@syncfusion/ej2-base';
import { FabComponent } from '@syncfusion/ej2-react-buttons';
import * as React from 'react';
import * as ReactDom from 'react-dom';
enableRipple(true);
function App() {
    return (<div>
            <div id="targetElement" style={{ position: 'relative', minHeight: '350px', border: '1px solid' }}></div>
            {/* To render Floating Action Button with position. */}
            <FabComponent id='fab' content='Add' target='#targetElement'></FabComponent>
        </div>);
}
export default App;
ReactDom.render(<App />, document.getElementById('button'));

app.tsx

import { enableRipple } from '@syncfusion/ej2-base';
import { FabComponent } from '@syncfusion/ej2-react-buttons';
import * as React from 'react';
import * as ReactDom from 'react-dom';

enableRipple(true);

function App() {
    return (
        <div>
            <div id="targetElement" style={{ position: 'relative', minHeight: '350px', border: '1px solid' }}></div>
            {/* To render Floating Action Button with position. */ }
            <FabComponent id='fab' content='Add' target='#targetElement'></FabComponent>
        </div>
    );
}
export default App;
ReactDom.render(<App />, document.getElementById('button'));

Click event

The floating action button control triggers the onclick event when you click on the floating action button. You can use this event to perform the required action.

app.jsx

import { FabComponent } from '@syncfusion/ej2-react-buttons';
import * as React from 'react';
import * as ReactDom from 'react-dom';
function App() {
    function onClick() {
        alert("Edit is clicked!");
    }
    return (<div>
            <div id="targetElement" style={{ position: 'relative', minHeight: '350px', border: '1px solid' }}></div>
            {/* To render Floating Action Button */}
            <FabComponent id='fab' iconCss='e-icons e-edit' content='Edit' onClick={onClick} target='#targetElement'></FabComponent>
        </div>);
}
export default App;
ReactDom.render(<App />, document.getElementById('button'));

app.tsx

import { FabComponent } from '@syncfusion/ej2-react-buttons';
import * as React from 'react';
import * as ReactDom from 'react-dom';

function App() {

    function onClick(): void {
        alert("Edit is clicked!");
    }

    return (
        <div>
            <div id="targetElement" style={{ position: 'relative', minHeight: '350px', border: '1px solid' }}></div>
            {/* To render Floating Action Button */ }
            <FabComponent id='fab' iconCss='e-icons e-edit' content='Edit' onClick={onClick} target='#targetElement'></FabComponent>
        </div>
    );
}
export default App;
ReactDom.render(<App />, document.getElementById('button'));

index.css

/* Represents the styles for loader */
#loader {
  color: #008cff;
  height: 40px;
  left: 45%;
  position: absolute;
  top: 45%;
  width: 30%;
}
