    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.
