Getting started in EJ2 TypeScript Toast control

7 May 20256 minutes to read

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

This application is integrated with the webpack.config.js configuration and uses the latest version of the webpack-cli. It requires node v14.15.0 or higher. For more information about webpack and its features, refer to the webpack documentation.

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 development environment

Open the command prompt from the required directory, and run the following command to clone the Syncfusion® JavaScript (Essential® JS 2) quickstart project from GitHub.

git clone https://github.com/SyncfusionExamples/ej2-quickstart-webpack- ej2-quickstart

After cloning the application in the ej2-quickstart folder, run the following command line to navigate to the ej2-quickstart folder.

cd ej2-quickstart

Add Syncfusion® JavaScript packages

Syncfusion® JavaScript (Essential® JS 2) packages are available on the npmjs.com public registry. You can install all Syncfusion® JavaScript (Essential® JS 2) controls in a single @syncfusion/ej2 package or individual packages for each control.

The quickstart application is preconfigured with the dependent @syncfusion/ej2 package in the ~/package.json file. Use the following command to install the dependent npm packages from the command prompt.

npm install

Import the Syncfusion® CSS styles

The toast CSS files are available in the ej2-notifications package folder. This can be referenced in the ~/src/styles/styles.css file of your application using the following code.

@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" />
</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();
