Getting started with JavaScript Toast control

This section explains the steps required to create the toast control using TypeScript and configure its properties using Essential JS 2 quickstart  seed repository.

Dependencies

The following list of dependencies are required to use the toast control in your application:

|-- @syncfusion/ej2-notifications
    |-- @syncfusion/ej2-popups
    |-- @syncfusion/ej2-buttons

Set up your development environment

  • Clone the Essential JS 2 quickstart application project from GitHub, and install the necessary npm packages using the following command.
git clone https://github.com/syncfusion/ej2-quickstart.git quickstart
cd quickstart
npm install

By default, the project is configured with all the Essential JS 2 dependencies. For better understanding, remove all the dependencies from src/system.config.js to get started with the toast component.

[src/system.config.js]

System.config({
    paths: {
        'syncfusion:': './node_modules/@syncfusion/',
    },
    map: {
        app: 'app',

        //Syncfusion packages mapping
        "@syncfusion/ej2-base": "syncfusion:ej2-base/dist/ej2-base.umd.min.js",
        "@syncfusion/ej2-buttons": "syncfusion:ej2-buttons/dist/ej2-buttons.umd.min.js",
        "@syncfusion/ej2-notifications": "syncfusion:ej2-notifications/dist/ej2-notifications.umd.min.js",
        "@syncfusion/ej2-popups": "syncfusion:ej2-popups/dist/ej2-popups.umd.min.js",
    },
    packages: {
        'app': { main: 'app', defaultExtension: 'js' }
    }
});

System.import('app');
  • The toast CSS files are available in the ej2-notifications package folder. This can be referenced in your application using the following code.

[src/styles/styles.css]

@import '../../node_modules/@syncfusion/ej2-notifications/styles/material.css';

Add toast to the Application

The toast message can be rendered by defining an title or content.

  • Add an HTML div tag with its id attribute as element in your index.html file to initialize the toast control.

[src/index.html]

<!DOCTYPE html>
<html lang="en">

<head>
    <title>Essential JS 2 Toast</title>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no" />
    <meta name="description" content="Essential JS 2" />
    <meta name="author" content="Syncfusion" />
    <link rel="shortcut icon" href="resources/favicon.ico" />
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />

    <!--style reference from app-->
    <link href="/styles/styles.css" rel="stylesheet" />

    <!--system js reference and configuration-->
    <script src="node_modules/systemjs/dist/system.src.js" type="text/javascript"></script>
    <script src="system.config.js" type="text/javascript"></script>
</head>

<body>
    <div style="margin: 50px;">
        <!--element which is going to render-->
        <div id="element"></div>
    </div>

</body>

</html>
  • Import the toast control to your app.ts file, and initialize it to the #element as shown.

[src/app/app.ts]

import { Toast } from '@syncfusion/ej2-notifications';

// Initialize Toast component
let toast: Toast = new Toast({
    title: 'Matt sent you a friend request',
    content: 'You have a new friend request yet to accept'
});

// Render initialized Toast
toast.appendTo('#element');

Running the application

  • Run the application in the browser using the following command.
npm start

Output will be as follows:

In the example, the #element is the id of the HTML element in a page to which the toast is initialized.

import {Toast} from '@syncfusion/ej2-notifications';
import { enableRipple } from '@syncfusion/ej2-base';

enableRipple(true);
let toast: Toast = new Toast({
    title: 'Matt sent you a friend request',
    content: 'You have a new friend request yet to accept',
    timeOut: 0
});
toast.appendTo('#element');
toast.show();
