Azure PurviewDataMap REST client library for JavaScript

Microsoft Purview Data Map provides the foundation for data discovery and data governance. Microsoft Purview Data Map is a cloud native PaaS service that captures metadata about enterprise data present in analytics and operation systems on-premises and cloud. Azure PurviewDataMap client provides a set of APIs in Purview Data Map Data Plane. For a full list of APIs, please refer to Data Map API.

Please rely heavily on our REST client docs to use this library

Getting started

Currently supported environments

• LTS versions of Node.js

Prerequisites

• You must have an Azure subscription to use this package.

Install the @azure-rest/purview-datamap package

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

npm install @azure-rest/purview-datamap

Create and authenticate a PurviewDataMapClient

To use an Azure Active Directory (AAD) token credential, provide an instance of the desired credential type obtained from the @azure/identity library.

To authenticate with AAD, 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 AAD application as environment variables: AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_CLIENT_SECRET

Examples

The following sections provide several code snippets covering some of the most common Purview DataMap scenarios, including:

• Get All Type Definitions

Get All Type Definitions

import PurviewDataMap from "@azure-rest/purview-datamap";
import { DefaultAzureCredential } from "@azure/identity";
import dotenv from "dotenv";
import { isUnexpected } from "@azure-rest/purview-datamap";

dotenv.config();

const endpoint = process.env["ENDPOINT"] || "";

async function main() {
  console.log("== List entity typedefs sample ==");
  const client = PurviewDataMap(endpoint, new DefaultAzureCredential());

  const result = await client.path("/atlas/v2/types/typedefs").get();

  if (isUnexpected(result)) {
    throw result;
  }
}

main().catch(console.error);

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.
