Azure Communication Network Traversal client library for JavaScript - version 1.1.0-beta.1

Azure Communication Network Traversal is managing tokens for Azure Communication Services.

It will provide TURN credentials to a user.

Getting started

Prerequisites

• An Azure subscription.
• An existing Communication Services resource. If you need to create the resource, you can use the Azure Portal, theAzure PowerShell, or the Azure CLI.

Installing

npm install @azure/communication-network-traversal
npm install @azure/communication-identity

Browser support

JavaScript Bundle

To use this client library in the browser, first you need to use a bundler. For details on how to do this, please refer to our bundling documentation.

Key concepts

Examples

Authentication

You can get a key and/or connection string from your Communication Services resource in Azure Portal. Once you have a key, you can authenticate the CommunicationRelayClient with any of the following methods:

Create KeyCredential with AzureKeyCredential before initializing the client

import { AzureKeyCredential } from "@azure/core-auth";
import { CommunicationRelayClient } from "@azure/communication-network-traversal";

const credential = new AzureKeyCredential(KEY);
const client = new CommunicationRelayClient(ENDPOINT, credential);

Using a connection string

import { CommunicationRelayClient } from "@azure/communication-network-traversal";

const connectionString = `endpoint=ENDPOINT;accessKey=KEY`;
const client = new CommunicationRelayClient(connectionString);

Using a TokenCredential

import { DefaultAzureCredential } from "@azure/identity";
import { CommunicationRelayClient } from "@azure/communication-network-traversal";

const credential = new DefaultAzureCredential();
const client = new CommunicationRelayClient(ENDPOINT, credential);

If you use a key to initialize the client you will also need to provide the appropriate endpoint. You can get this endpoint from your Communication Services resource in Azure Portal.

Usage

Creating an instance of CommunicationRelayClient

import { CommunicationRelayClient } from "@azure/communication-network-traversal";

const client = new CommunicationRelayClient(CONNECTION_STRING);

Creating an instance of CommunicationIdentityClient to create a user

import { CommunicationIdentityClient } from "@azure/communication-identity";

const client = new CommunicationIdentityClient(CONNECTION_STRING);

Use the createUser method to create a new user.

const user = await client.createUser();

Getting the configurationRelay

Use the getConfigurationRelay method to get new TURN credentials providing a user

const config = await relayClient.getRelayConfiguration(user);

Also you can call the getConfigurationRelay method without providing a user

const config = await relayClient.getRelayConfiguration();

You can specify a RouteType when calling getConfigurationRelay

const config = await relayClient.getRelayConfiguration(user, "nearest");

Troubleshooting
