Google Cloud Runtime Config: Node.js Client

Node.js implementation of rcloadenv. Wraps execution of a given command and loads variables from the Google Cloud Runtime Config API into that process.

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

Quickstart

Installing the client library

npm install @google-cloud/rcloadenv

Using the client library

// import the npm module
const rcloadenv = require('@google-cloud/rcloadenv');

async function quickstart() {
  // Just load raw variables from the Runtime Config service:
  const vars = await rcloadenv.getVariables('my-config');
  console.log(`${vars.length} variables found!`);
  vars.forEach(console.log);

  // Load the variables and apply them to the current environment
  await rcloadenv.getAndApply('my-config');
  console.log(process.env.fruit);

  // Load the variables and mix them into a provided object
  const newEnv = Object.assign({}, process.env);
  const env = await rcloadenv.getAndApply('my-config', newEnv);
  console.log(env.veggie);
}
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. 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/rcloadenv@legacy-8 installs client libraries for versions compatible with Node.js 8.

Versioning

This library follows Semantic Versioning.

This library is considered to be in preview. This means it is still a work-in-progress and under active development. Any release is subject to backwards-incompatible changes at any time.
