Node.js implementation of rcloadenv.
Wraps execution of a given command and loads variables from the Google Cloud Runtime Config API into that process.
Using npm:
npm install -g @google-cloud/rcloadenv
Using yarn:
yarn global add @google-cloud/rcloadenv
Using npm:
npm install @google-cloud/rcloadenv
Using yarn:
yarn add @google-cloud/rcloadenv
Now wrap your app's start script with rcloadenv in package.json:
"scripts": {
"start": "rcloadenv my-config -- node app.js"
}Output of rcloadenv --help:
Wrap execution of the given command with runtime-config variables.
Usage: rcloadenv <configName> [options] -- [args...]
Options:
--version Show version number [boolean]
--debug, -d Print debugging information. [boolean]
--except, -E If provided, a list of of runtime-config variables to exclude, otherwise all
runtime-config variables will be used. [array]
--only, -O If provided, a list of of runtime-config variables to load, otherwise all runtime-config
variables will be used. [array]
--override, -o Determines the behavior of rcloadenv in the case when a runtime-config variable conflicts
with a variable already available in the environment. If true, a runtime-config variable
will override the existing environment variable, otherwise the existing environment
variable will be kept. [boolean] [default: false]
--projectId, --project, -p The project where the specified config is located. [string]
--help Show help [boolean]
Examples:
rcloadenv my-config -- bash -c 'echo $MY_VARIABLE_NAME' Print a variable's value from the specified config.
rcloadenv my-config --only var1 var2 -- node app.js Only load two variables from runtime-config.
rcloadenv my-config --except var1 var2 -- node app.js Load all but two variables from runtime-config.
rcloadenv my-config --debug -- node app.js Print debugging information while loading variables.
rcloadenv my-config --projectId my-project-id -- node app.js Specify the project ID to use when loading variables.

Using npm:
npm install @google-cloud/rcloadenv
Using yarn:
yarn add @google-cloud/rcloadenv
Just load raw variables from the Runtime Config service:
const rcloadenv = require('@google-cloud/rcloadenv');
rcloadenv.getVariables('my-config')
.then((variables) => {
variables.forEach((variable) => {
console.log(variable);
});
})
.catch((err) => {
console.error('ERROR:', err);
});Load the variables and apply them to the current environment:
const rcloadenv = require('@google-cloud/rcloadenv');
rcloadenv.getAndApply('my-config')
.then(() => {
console.log(process.env.MY_VAR);
})
.catch((err) => {
console.error('ERROR:', err);
});Load the variables and mix them into a provided object:
const rcloadenv = require('@google-cloud/rcloadenv');
const newEnv = Object.assign({}, process.env);
rcloadenv.getAndApply('my-config', newEnv)
.then((env) => {
console.log(env.MY_VAR);
})
.catch((err) => {
console.error('ERROR:', err);
