Azure Purview Scanning is a fully managed cloud service whose users can scan your data into your data estate (also known as your catalog). Scanning is a process by which the catalog connects directly to a data source on a user-specified schedule.

• Scan your data into your catalog
• Examine your data
• Extract schemas from your data

Please rely heavily on the service's documentation and our Rest client docs to use this library

Key links:

• Source code
• Package (NPM)
• API reference documentation
• Product documentation

• LTS versions of Node.js

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

Follow these instructions to create your Purview resource

Install the Azure Purview Scanning client library for JavaScript with npm:

npm install @azure-rest/purview-scanning

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 and enable AAD authentication on your Purview resource

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

Use the returned token credential to authenticate the client:

import PurviewScanning from "@azure-rest/purview-scanning";
import { DefaultAzureCredential } from "@azure/identity";
const client = PurviewScanning(
  "https://.purview.azure.com",
  new DefaultAzureCredential()
);

This client is one of our Rest clients. We highly recommend you read how to use a Rest client here.

The following section shows you how to initialize and authenticate your client, then list all of your data sources.

• List All Data Sources

import PurviewScanning, { paginate, DataSourceOutput, PagedAsyncIterableIterator, PageSettings, isUnexpected } from "@azure-rest/purview-scanning";
import { DefaultAzureCredential } from "@azure/identity";

async function main(): Promise<void> {
  console.log("== List dataSources ==");
  const client = PurviewScanning(
    "https://.purview.azure.com",
    new DefaultAzureCredential()
  );

  const dataSources = await client.path("/datasources").get();
  if (isUnexpected(dataSources)) {
    throw dataSources.body.error;
  }
  const iter = paginate(client, dataSources);

  const items: DataSourceOutput[] = [];

  for await (const item of <PagedAsyncIterableIterator<DataSourceOutput, (DataSourceOutput)[], PageSettings>>iter) {
    items.push(item);
  }

  console.log(items?.map((ds) => ds.name).join("\n"));
}

main().catch(console.error);

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.
