DevExtreme Angular - Application Template

The DevExtreme Angular Application Template helps you create a simple Angular application with a navigation menu and several sample views in a responsive layout (see live preview).

DevExtreme Angular Template

Generate a New Application

npx devextreme-cli new angular-app app-name
cd app-name
npm run start

The generated application already contains the DataGrid and Form components. You can find their configurations in the src\app\pages\tasks\tasks.component.html and src\app\pages\profile\profile.component.html files correspondingly.


The application includes two layouts. The only difference between them is where the toolbar is located.

  • Outer Toolbar (default)
    DevExtreme Angular Template - Outer toolbar

  • Inner Toolbar
    DevExtreme Angular Template - Inner toolbar

To switch to another layout, open the src\app\app.component.html file and replace the app-side-nav-outer-toolbar element with app-side-nav-inner-toolbar:

<app-side-nav-inner-toolbar title="{{appInfo.title}}">
    <!-- Layout content is here -->

To generate a new application with an inner toolbar, set the --layout flag to side-nav-inner-toolbar:

npx devextreme-cli new angular-app app-name --layout=side-nav-inner-toolbar

Add a New View

Run the following command to add a new view. --icon specifies an icon from the DevExtreme icon library.

npx devextreme add view view-name [--icon=IconName]

You can find the added view under the src\app\pages folder. This command also creates a navigation menu item for the added view in the src\app\app-navigation.ts file.

Configure the Navigation Menu

Configure Menu Items

Edit the src\app\app-navigation.ts file to configure navigation menu items. Each item configuration can have the following fields:

  • text - the item's text

  • icon - the item's icon

  • path - a navigation path associated with the item

  • items - child items

A menu item should either navigate to a page OR include subitems. For that reason, do not specify both path and items for the same menu item.
    text: 'Category',
    icon: 'folder',
    items: [{
        text: 'About',
        path: '/about'

Hide the Menu in the Closed State

In the closed state, the navigation menu is partially visible because it displays item icons. If the items do not have icons, you can hide the menu. To do this, open the SideNavOuterToolbarComponent or SideNavInnerToolbarComponent (depending on the layout) and change the updateDrawer() function as follows:

// ...
export class SideNavInnerToolbarComponent implements OnInit {
    // ...
    updateDrawer() {
        // ...
        this.minMenuSize = 0;

Add a Custom Toolbar Item

The application template uses the DevExtreme Toolbar component. The Toolbar is part of the HeaderComponent whose configuration is in the src\app\shared\components\header directory. To add a custom toolbar item, open the header.component.html file in this directory and add a dxi-item element inside dx-toolbar. Refer to the items help section for information on dxi-item attributes.

The following code adds a search button to the toolbar:

    <dx-toolbar class="header-toolbar">
        <!-- ... -->
                icon: 'search',
                onClick: startSearch
        <!-- ... -->
export class HeaderComponent {
    // ...
    search = new EventEmitter<void>();

    startSearch = () => {;
<app-header ... 
<!-- ... -->
export class SideNavOuterToolbarComponent implements OnInit {
    // ...
    search() {

In the code above, the button click handler is declared in the SideNavOuterToolbarComponent. This component is applied when the outer toolbar layout is used. If the application uses the inner toolbar layout, add the same code to the SideNavInnerToolbarComponent.

Configure Themes

Switch the Theme

The DevExtreme Angular Template uses a main theme for the view content and an additional theme (color swatch) for the navigation menu. To switch to another theme, open the src\themes\metadata.base.json or src\themes\metadata.additional.json file and assign a theme name to the baseTheme field:

    // ...
    "baseTheme": "",
    // ...
    // ...
    "baseTheme": "generic.light",
    // ...

You can find all theme names in the Predefined Themes help topic. Use theme names without the dx prefix.

Run the following command to rebuild themes:

npm run build-themes

Create a Custom Theme

You can use the DevExtreme ThemeBuilder to create custom themes based on predefined themes. Follow the steps below:

  1. Import src\themes\metadata.base.json or src\themes\metadata.additional.json to the ThemeBuilder.

  2. Customize the theme.

  3. Export theme metadata to the initial file (see Postpone Customization).

Run the following command to rebuild themes:

npm run build-themes

Apply a Color Swatch

Color swatches are secondary color schemes used alongside a primary color scheme.

In the DevExtreme Angular Template, a color swatch is applied to the navigation menu and is configured in the src\themes\metadata.additional.json file. To apply this color swatch to an element, add the dx-swatch-additional class to this element:

<div class="dx-swatch-additional">
    <!-- Your content here -->

Apply Theme Variables to Custom Elements

Theme variables are defined in the src\themes\generated\variables.base.scss and src\themes\generated\variables.additional.scss files. Apply them to custom elements, so that the elements have a uniform appearance with the rest of the application.

The following code applies the $base-accent variable as the background-color of my-element:

// Your SCSS file
@import "../../../themes/generated/variables.base.scss";

#my-element {
    background-color: $base-accent;


A DevExtreme Angular application includes authentication UI and API. Client-side routing is configured so that unauthenticated users can navigate to authentication pages only. These pages allow the users to sign in, create a new account, or reset the password.

Authentication pages are rendered by the UnauthenticatedContentComponent.

Do not rely on client-side routing to protect your application from unauthorized access. Always verify user credentials on the back end.

Integrate with a Back End

Stub authentication functions for back-end requests are implemented in the AuthService. Update these functions to make actual requests to your back end.

Each function returns an object with the following fields:

Field Description
isOk A Boolean value that is true if the request was successful and false otherwise.
message An error message (if an error occurred).
data The request result (information about the authenticated user).

Get User Information

User information is provided by the same AuthService. You can use its getUser() method to access this information:

import { Component } from '@angular/core';
import { AuthService } from './shared/services';

    // ...
export class AppComponent  {
    constructor(private authService: AuthService) { }

    ngOnInit() {
        this.authService.getUser().then((e) => {
            if ( {
                // User is authenticated 

Create an Empty Application

To generate an application without views and a navigation menu, use the --empty flag:

npx devextreme-cli new angular-app app-name --empty
