Cloud Data Loss Prevention: Node.js Client

release level npm version codecov

The Data Loss Prevention API provides programmatic access to a powerful detection engine for personally identifiable information and other privacy-sensitive data in unstructured data streams.

Read more about the client libraries for Cloud APIs, including the older Google APIs Client Libraries, in Client Libraries Explained.

Table of contents:

Quickstart

Before you begin

  1. Select or create a Cloud Platform project.
  2. Enable billing for your project.
  3. Enable the Cloud Data Loss Prevention API.
  4. Set up authentication with a service account so you can access the API from your local workstation.

Installing the client library

npm install @google-cloud/dlp

Using the client library

  // Instantiates a client
  const dlp = new DLP.DlpServiceClient();

  // The string to inspect
  const string = 'Robert Frost';

  // The project ID to run the API call under
  const projectId = process.env.GCLOUD_PROJECT;

  // The minimum likelihood required before returning a match
  const minLikelihood = 'LIKELIHOOD_UNSPECIFIED';

  // The maximum number of findings to report (0 = server maximum)
  const maxFindings = 0;

  // The infoTypes of information to match
  const infoTypes = [{name: 'PERSON_NAME'}, {name: 'US_STATE'}];

  // Whether to include the matching string
  const includeQuote = true;

  // Construct item to inspect
  const item = {value: string};

  // Construct request
  const request = {
    parent: dlp.projectPath(projectId),
    inspectConfig: {
      infoTypes: infoTypes,
      minLikelihood: minLikelihood,
      limits: {
        maxFindingsPerRequest: maxFindings,
      },
      includeQuote: includeQuote,
    },
    item: item,
  };

  // Run request
  const [response] = await dlp.inspectContent(request);
  const findings = response.result.findings;
  if (findings.length > 0) {
    console.log(`Findings:`);
    findings.forEach(finding => {
      if (includeQuote) {
        console.log(`\tQuote: ${finding.quote}`);
      }
      console.log(`\tInfo type: ${finding.infoType.name}`);
      console.log(`\tLikelihood: ${finding.likelihood}`);
    });
  } else {
    console.log(`No findings.`);
  }

Versioning

This library follows Semantic Versioning.

This library is considered to be in beta. This means it is expected to be mostly stable while we work toward a general availability release; however, complete stability is not guaranteed. We will address issues and requests against beta libraries with a high priority.
