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.

A comprehensive list of changes in each version may be found in the CHANGELOG.

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

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 = 'my-project';

async function quickStart() {
  // 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: `projects/${projectId}/locations/global`,
    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.');
  }
}
quickStart();

Supported Node.js Versions

Our client libraries follow the Node.js release schedule. Libraries are compatible with all current active and maintenance versions of Node.js.

Client libraries targetting some end-of-life versions of Node.js are available, and can be installed via npm dist-tags. The dist-tags follow the naming convention legacy-(version).

Legacy Node.js versions are supported as a best effort:

  • Legacy versions will not be tested in continuous integration.
  • Some security patches may not be able to be backported.
  • Dependencies will not be kept up-to-date, and features will not be backported.

Legacy tags available

  • legacy-8: install client libraries from this dist-tag for versions compatible with Node.js 8.

Versioning

This library follows Semantic Versioning.

This library is considered to be General Availability (GA). This means it is stable; the code surface will not change in backwards-incompatible ways unless absolutely necessary (e.g. because of critical security issues) or with an extensive deprecation period. Issues and requests against GA libraries are addressed with the highest priority.
