Google APIs Proto Files: Node.js Client

release level npm version

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. 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-proto-files@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.
