Quickstart: Get started with UI Framework Base Components


Functionality described on this document is currently in private preview. Private preview includes access to client libraries and documentation for testing purposes that are not yet available publicly. Apply to become an early adopter by filling out the form for preview access to Azure Communication Services.

Get started with Azure Communication Services by using the UI Framework to quickly integrate communication experiences into your applications. In this quickstart, you'll learn how integrate UI Framework base components into your application to build communication experiences.

UI Framework components come in two flavors: Base and Composite.

  • Base components represent discrete communication capabilities; they're the basic building blocks that can be used to build complex communication experiences.
  • Composite components are turn-key experiences for common communication scenarios that have been built using base components as building blocks and packaged to be easily integrated into applications.


Setting up

UI Framework requires a React environment to be setup. Next we will do that. If you already have a React App, you can skip this section.

Set Up React App

We'll use the create-react-app template for this quickstart. For more information, see: Get Started with React

npx create-react-app my-app

cd my-app

At the end of this process, you should have a full application inside of the folder my-app. For this quickstart, we'll be modifying files inside of the src folder.

Install the package

Use the npm install command to install the Azure Communication Services Calling client library for JavaScript. Move the provided tarball (Private Preview) over to the my-app directory.

//For Private Preview install tarball

npm install --save ./{path for tarball}

The --save option lists the library as a dependency in your package.json file.

Run Create React App

Let's test the Create React App installation by running:

npm run start   

Object model

The following classes and interfaces handle some of the major features of the Azure Communication Services UI client library:

Name Description
Provider Fluent UI provider that allows developers to modify underlying Fluent UI components
CallingProvider Calling Provider to instantiate a call. Required to add extra components
ChatProvider Chat Provider to instantiate a chat thread. Required to add extra components
MediaGallery Base component that shows call participants and their remote video streams
MediaControls Base component to control call including mute, video, share screen
ChatThread Base component that renders a chat thread with typing indicators, read receipts, etc.
SendBox Base component that allows user to input messages that will be sent to the joined thread

Initialize Calling and Chat Providers using Azure Communication Services credentials

Go to the src folder inside of my-app and look for the file app.js. Here we'll drop the following code to initialize our Calling and Chat providers. These providers are responsible for maintaining the context of the call and chat experiences. You can choose which one to use depending on the type of communication experience you're building. If needed, you can use both at the same time. To initialize the components, you'll need an access token retrieved from Azure Communication Services. For details on how to get access tokens, see: create and manage access tokens.


The components don't generate access tokens, group IDs, or thread IDs. These elements come from services that go through the proper steps to generate these IDs and pass them to the client application. For more information, see: Client Server Architecture.

For Example: The Chat Provider expects that the userId associated to the token being used to initialize it has already been joined to the threadId being provided. If the token hasn't been joined to the thread ID, then the Chat Provider will fail. For more information on chat, see: Getting Started with Chat

We'll use a Fluent UI theme to enhance the look and feel of the application:


import {CallingProvider, ChatProvider} from "@azure/acs-ui-sdk"
import { mergeThemes, teamsTheme } from '@fluentui/react-northstar';
import { Provider } from '@fluentui/react-northstar/dist/commonjs/components/Provider/Provider';
import { svgIconStyles } from '@fluentui/react-northstar/dist/es/themes/teams/components/SvgIcon/svgIconStyles';
import { svgIconVariables } from '@fluentui/react-northstar/dist/es/themes/teams/components/SvgIcon/svgIconVariables';
import * as siteVariables from '@fluentui/react-northstar/dist/es/themes/teams/siteVariables';

const iconTheme = {
  componentStyles: {
    SvgIcon: svgIconStyles
  componentVariables: {
    SvgIcon: svgIconVariables

function App(props) {

  return (
    <Provider theme={mergeThemes(iconTheme, teamsTheme)}>
        displayName={/*Insert Display Name to be used for the user*/}
        groupId={/*Insert GUID for group call to be joined*/}
        token={/*Insert the Azure Communication Services access token*/}
        refreshTokenCallback={/*Optional, Insert refresh token call back function*/}
            // Add Calling Components Here

        {/*Note: Make sure that the userId associated to the token has been added to the provided threadId*/}

        token={/*Insert the Azure Communication Services access token*/}
        displayName={/*Insert Display Name to be used for the user*/}
        threadId={/*Insert id for group chat thread to be joined*/}
        endpointUrl={/*Insert the environment URL for the Azure Resource used*/}
        refreshTokenCallback={/*Optional, Insert refresh token call back function*/}
            //  Add Chat Components Here

export default App;

Once initialized, this provider lets you build your own layout using UI Framework Base Components and any extra layout logic. The provider takes care of initializing all the underlying logic and properly connecting the different components together. Next we'll use various base components provided by UI Framework to build communication experiences. You can customize the layout of these components and add any other custom components that you want to render with them.

Build UI Framework Calling Component Experiences

For Calling, we'll use the MediaGallery and MediaControls Components. For more information about them, see UI Framework Capabilities. To start, in the src folder, create a new file called CallingComponents.js. Here we'll initialize a function component that will hold our base components to then import in app.js. You can add extra layout and styling around the components.


import {MediaGallery, MediaControls, MapToCallConfigurationProps, connectFuncsToContext} from "@azure/acs-ui-sdk"

function CallingComponents(props) {

  if (props.isCallInitialized) {props.joinCall()}

  return (
    <div style = {{height: '35rem', width: '30rem', float: 'left'}}>

export default connectFuncsToContext(CallingComponents, MapToCallConfigurationProps);

At the bottom of this file, we exported the calling components using the connectFuncsToContext method from the UI Framework to connect the calling UI components to the underlying state using the mapping function MapToCallingSetupProps. This method yields the component having its props populated, which we then use to check state and join the call. Using the isCallInitialized property to check whether the CallAgent is ready and then we use the joinCall method to join in. UI Framework supports custom mapping functions to be used for scenarios where developers want to control how data is pushed to the components.

Build UI Framework Chat Component Experiences

For Chat, we will use the ChatThread and SendBox components. For more information about these components, see UI Framework Capabilities. To start, in the src folder, create a new file called ChatComponents.js. Here we'll initialize a function component that will hold our base components to then import in app.js.


import {ChatThread, SendBox} from '@azure/acs-ui-sdk'

function ChatComponents() {

  return (
    <div style = {{height: '35rem', width: '30rem', float: 'left'}}>
        <ChatThread />
        <SendBox />
    </div >

export default ChatComponents;

Add Calling and Chat Components to the main application

Back in the app.js file, we will now add the components to the CallingProvider and ChatProvider like shown below.


import ChatComponents from './ChatComponents';
import CallingComponents from './CallingComponents';

<Provider ... >
    <CallingProvider .... >

    <ChatProvider .... >
        <ChatComponents />

Run quickstart

To run the code above use the command:

npm run start   

To fully test the capabilities, you will need a second client with calling and chat functionality to join the call and chat thread. See our Calling Hero Sample and Chat Hero Sample as potential options.

Clean up resources

If you want to clean up and remove a Communication Services subscription, you can delete the resource or resource group. Deleting the resource group also deletes any other resources associated with it. Learn more about cleaning up resources.
