Getting started in EJ2 TypeScript AppBar control

6 May 20256 minutes to read

This section explains how to create a simple AppBar and configure its available functionalities in TypeScript 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 AppBar component in your application.

|-- @syncfusion/ej2-navigations
    |-- @syncfusion/ej2-base

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

To render AppBar component, need to import navigations and its dependent components styles as given below in the ~/src/styles/styles.css file, as shown below:

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

Adding AppBar component to the application

Open the application in Visual Studio Code and add the Syncfusion® JavaScript UI controls.

Add the HTML div tag with its id attribute as AppBar in your index.html file to initialize the AppBar.

[src/index.html]

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

<head>
    <title>Essential JS 2</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" />

</head>

<body>
    <div class="control-container">
        <div id="appbar"></div>
    </div>
</body>

</html>

Import the AppBar component in your app.ts file and initialize it with the #AppBar.

[src/app/app.ts]

import { AppBar } from "@syncfusion/ej2-navigations";

const appbarObj = new AppBar({
  colorMode: 'Primary'
});
appbarObj.appendTo("#appbar");

Run the application

Run the application in the browser using the following command:

npm start

The following example shows a basic AppBar component.

import { AppBar } from "@syncfusion/ej2-navigations";
import { Button } from "@syncfusion/ej2-buttons";

const appbarObj: AppBar = new AppBar({
  colorMode: 'Primary'
});
appbarObj.appendTo("#appbar");

const defaultButtonMenuObj: Button = new Button({ cssClass: 'e-inherit', iconCss: 'e-icons e-menu' });
defaultButtonMenuObj.appendTo('#defaultButtonMenu');

const defaultButtonLoginObj: Button = new Button({ cssClass: 'e-inherit', content: 'FREE TRIAL' });
defaultButtonLoginObj.appendTo('#defaultButtonLogin');
