Google APIs Proto Files: Node.js Client

release level npm version codecov

All of the Google API's protocol buffer files

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

Installing the client library

npm install google-proto-files

Using the client library

const protos = require('google-proto-files');

async function quickstart() {
  // Get a directory path by executing as a function
  const files = protos.getProtoPath('logging', 'v2');
  // node_modules/google-proto-files/google/logging/v2

  // Get a path to the entry proto file for a specific API version
  // node_modules/google-proto-files/google/pubsub/v1/pubsub.proto

  // Load a proto which depends on google common protos.
  const root1 = await protos.load('./cloudcats.proto');
  const service1 = root1.lookup('example.MyService');

  // Load protos synchronously
  const root2 = protos.loadSync('./cloudcats.proto');
  const service2 = root2.lookup('example.MyService');

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 targeting 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.


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.
