Package (NPM) | API reference documentation |

Getting started

Currently supported environments

• LTS versions of Node.js
• Latest versions of Safari, Chrome, Edge and Firefox.

See our support policy for more details.

Prerequisites

• An Azure subscription.

Install the @azure/arm-iotoperations package

Install the Azure IoTOperations client library for JavaScript with npm:

npm install @azure/arm-iotoperations

Create and authenticate a IoTOperationsClient

To create a client object to access the Azure IoTOperations API, you will need the endpoint of your Azure IoTOperations resource and a credential. The Azure IoTOperations client can use Azure Active Directory credentials to authenticate. You can find the endpoint for your Azure IoTOperations resource in the Azure Portal.

You can authenticate with Azure Active Directory using a credential from the @azure/identity library or an existing AAD Token.

To use the DefaultAzureCredential provider shown below, or other credential providers provided with the Azure SDK, please install the @azure/identity package:

npm install @azure/identity

You will also need to register a new AAD application and grant access to Azure IoTOperations by assigning the suitable role to your service principal (note: roles such as "Owner" will not grant the necessary permissions). Set the values of the client ID, tenant ID, and client secret of the AAD application as environment variables: AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_CLIENT_SECRET.

For more information about how to create an Azure AD Application check out this guide.

const { IoTOperationsClient } = require("@azure/arm-iotoperations");
const { DefaultAzureCredential } = require("@azure/identity");
// For client-side applications running in the browser, use InteractiveBrowserCredential instead of DefaultAzureCredential. See https://aka.ms/azsdk/js/identity/examples for more details.

const subscriptionId = "00000000-0000-0000-0000-000000000000";
const client = new IoTOperationsClient(new DefaultAzureCredential(), subscriptionId);

// For client-side applications running in the browser, use this code instead:
// const credential = new InteractiveBrowserCredential({
//   tenantId: "<YOUR_TENANT_ID>",
//   clientId: "<YOUR_CLIENT_ID>"
// });
// const client = new IoTOperationsClient(credential, subscriptionId);

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

IoTOperationsClient

IoTOperationsClient is the primary interface for developers using the Azure IoTOperations client library. Explore the methods on this client object to understand the different features of the Azure IoTOperations service that you can access.

Troubleshooting

Logging

Enabling logging may help uncover useful information about failures. In order to see a log of HTTP requests and responses, set the AZURE_LOG_LEVEL environment variable to info. Alternatively, logging can be enabled at runtime by calling setLogLevel in the @azure/logger:

const { setLogLevel } = require("@azure/logger");
setLogLevel("info");

For more detailed instructions on how to enable logs, you can look at the @azure/logger package docs.
