@restorecommerce/service-config

An opinionated wrapper of nconf.

Configuration settings are obtain from the following sources in the given order:

• Command argument
• Environment variables
• Configuration files

1.) and 2.) support passing nested object properties with the following pattern:

# Original Configuration JSON file
{
  "someObject": {
    "paramA": "A"
  }
}

Can be overridden via env var or command line parameter someObject__paramA. So the nesting is designated by a double underscore.

3.) tries to load the following configuration files from the cfg folder:

• Default configuration file config.json
• Additional sub-variants added to the value of the environment variable NODE_ENV for example a value development:development would try to load config_development.json

Usage

import { createServiceConfig } from '@restorecommerce/service-config';

...

const cfg = createServiceConfig('./test', { stageVar: 'NODE_ENV', logger: logger});
const testSetting = cfg.get('test');
