Cloud Data Loss Prevention: Node.js Client

release level npm version

DLP API client for Node.js

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.

Table of contents:


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) {
    findings.forEach(finding => {
      if (includeQuote) {
        console.log(`\tQuote: ${finding.quote}`);
      console.log(`\tInfo type: ${}`);
      console.log(`\tLikelihood: ${finding.likelihood}`);
  } else {
    console.log('No findings.');

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. If you are using an end-of-life version of Node.js, we recommend that you update as soon as possible to an actively supported LTS version.

Google's client libraries support legacy versions of Node.js runtimes on a best-efforts basis with the following warnings:

  • Legacy versions are not tested in continuous integration.
  • Some security patches and features cannot be backported.
  • Dependencies cannot be kept up-to-date.

Client libraries targeting some end-of-life versions of Node.js are available, and can be installed through npm dist-tags. The dist-tags follow the naming convention legacy-(version). For example, npm install @google-cloud/dlp@legacy-8 installs client libraries for versions compatible with Node.js 8.


This library follows Semantic Versioning.

This library is considered to be 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 stable libraries are addressed with the highest priority.
