Getting started

Currently supported environments

  • LTS versions of Node.js

Prerequisites

Install the @azure-rest/batch package

Install the Azure Batch REST client library for JavaScript with npm:

npm install @azure-rest/batch

Create and authenticate a BatchClient

Azure batch supports authentication either via Microsoft Entra ID or Shared Key.

Microsoft Entra ID

To use an Microsoft Entra ID token credential, provide an instance of the desired credential type obtained from the @azure/identity library.

To authenticate with Microsoft Entra ID, you must first npm install @azure/identity

After setup, you can choose which type of credential from @azure/identity to use. As an example, DefaultAzureCredential can be used to authenticate the client.

Set the values of the client ID, tenant ID, and client secret of the Microsoft Entra ID application as environment variables: AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_CLIENT_SECRET

Shared Key

To use shared key to authenticate, you must first npm install @azure/core-auth, then provide the account name and account key to construct the an AzureNamedKeyCredential credential from @azure/core-auth

import { AzureNamedKeyCredential } from "@azure/core-auth";
import createClient from "@azure-rest/batch";

const credential = new AzureNamedKeyCredential("<account name>", "<account key>");
const batchClient = createClient("<account endpoint>", credential);

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:

import { setLogLevel } from "@azure/logger";

setLogLevel("info");

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