18 May 20265 minutes to read

This section explains how to create a simple Syncfusion Chat component and configure its features in an Angular application.

To get started quickly with the Angular Chat UI component, you can check out this video tutorial:

Setup angular environment

You can use the Angular CLI to set up your Angular applications. To install the Angular CLI, use the following command.

npm install -g @angular/cli

Create an Angular Application

Create a new Angular application using the following Angular CLI command:

ng new my-app

This command will prompt you for a few settings for the new project, such as which stylesheet format to use.

By default, it will create a CSS-based application.

Then the CLI also displays an additional prompt asking whether to enable Server‑Side Rendering (SSR) and Static Site Generation (SSG), as shown below:

For this setup, when prompted for the Server-side rendering (SSR) option, choose the appropriate configuration.

Then the CLI displays another prompt related to AI tooling support, as shown below:

Any preferred option can be selected based on the development workflow or project needs.

Next, navigate to the project folder:

cd my-app

Adding Syncfusion Chat UI package

All available Essential JS 2 packages are published in the npmjs.com registry. Install the Chat UI component with the following command:

npm install @syncfusion/ej2-angular-interactive-chat

Adding CSS reference

The following CSS files are available in ../node_modules/@syncfusion package folder.
This can be referenced in [src/styles.css] using following code.

@import "../node_modules/@syncfusion/ej2-base/styles/tailwind3.css";
@import '../node_modules/@syncfusion/ej2-inputs/styles/tailwind3.css';
@import '../node_modules/@syncfusion/ej2-navigations/styles/tailwind3.css';
@import '../node_modules/@syncfusion/ej2-popups/styles/tailwind3.css';
@import '../node_modules/@syncfusion/ej2-buttons/styles/tailwind3.css';
@import '../node_modules/@syncfusion/ej2-dropdowns/styles/tailwind3.css';
@import '../node_modules/@syncfusion/ej2-angular-interactive-chat/styles/tailwind3.css';

Adding Chat UI component

Modify the template in [src/app/app.component.ts] file to render the Angular Chat UI component. Add the Angular Chat UI by using <ejs-chatui> selector in template section of the app.component.ts file.

import { Component } from '@angular/core';
import { ChatUIModule } from '@syncfusion/ej2-angular-interactive-chat';

@Component({
    imports: [ ChatUIModule ],
    standalone: true,
    selector: 'app-root',
    // specifies the template string for the Chat UI component
    template: `<div ejs-chatui ></div>`
})
export class AppComponent  { }

Configure User

To define the chat content, use the user property assigns an identity to the current user, which is essential for distinguishing the user’s messages from those of other participants.

app.component.ts

import { ChatUIModule } from '@syncfusion/ej2-angular-interactive-chat';
import { UserModel } from '@syncfusion/ej2-interactive-chat';

import { Component } from '@angular/core';


@Component({
    imports: [ ChatUIModule ],
    standalone: true,
    selector: 'app-root',
    // specifies the template string for the Chat UI component
    template: `<div id="chatui" ejs-chatui [user]="currentUserModel">
        <e-messages>
            <e-message text="Hi Michale, are we on track for the deadline?" [author]="currentUserModel"></e-message>
            <e-message text="Yes, the design phase is complete." [author]="michaleUserModel"></e-message>
            <e-message text="I’ll review it and send feedback by today." [author]="currentUserModel"></e-message>
        </e-messages>
    </div>`
})

export class AppComponent {
    public currentUserModel: UserModel = { user: 'Albert', id: 'user1' };
    public michaleUserModel: UserModel = { user: 'Michale Suyama', id: 'user2' };
}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Run the application

After completing the configuration required to render a basic Chat UI, run the following command to display the output in your default browser.

ng serve

The following example illustrates the output in your browser.

app.component.ts

import { ChatUIModule } from '@syncfusion/ej2-angular-interactive-chat';
import { UserModel, FileAttachmentSettingsModel } from '@syncfusion/ej2-interactive-chat';
import { Component } from '@angular/core';


@Component({
    imports: [ ChatUIModule ],
    standalone: true,
    selector: 'app-root',
    // specifies the template string for the Chat UI component
    template: `<div ejs-chatui id='chatui' [user]="currentUserModel"></div>`
})

export class AppComponent {
public currentUserModel: UserModel = { user: 'Albert', id: 'user1' };
}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
