Configuring system JS

The Syncfusion Message packages should be mapped in the system.config.js configuration file.

System.config({
    paths: {
        'npm:': './node_modules/',
        'syncfusion:': 'npm:@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-popups":"syncfusion:ej2-popups/dist/ej2-popups.umd.min.js",
        "@syncfusion/ej2-notifications":"syncfusion:ej2-notifications/dist/ej2-notifications.umd.min.js"
    },
    packages: {
        'app': { main: 'app', defaultExtension: 'js' }
    }
});

System.import('app');

Adding CSS reference

The combined CSS files are available in the Essential JS 2 package root folder. This can be referenced in the [src/styles/styles.css] file using the following code.

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

To add the individual control CSS, refer to the individual control theme section. To use the combined control styles, make use of Syncfusion CRG (Custom Resource Generator) in the application.

Add Message control

Now, start adding the Essential JS 2 Message control to the application. To get started, add the HTML <div> element to the index.html file.

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

<head>
    <title>Essential JS 2 Message control</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 Message" />
    <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" />
    <link href="/styles/styles.css" rel="stylesheet" />
</head>
<body>
    <!--Element which will render as Message-->
    <div id="msg"></div>
</body>

</html>

Add the following code in the app.ts file to convert the div element to message control.
