Config-Envify

Some of the older nodejs config management packages do not support overwriting via environmental variables.

How to use

Just include (will make npm package soon) the file in your lib and use it inside your config file. Example:

const envify = require('./config-envify');

module.exports = envify.envify({
  // Your normal config
});

How it works

It wraps your current config without effecting its values. When you run your application, it checkes env variables and convert your current configs to env friendly variables (Uppercased Underscored). It loops over your config and see if it finds any similar key in process.env. If found, will update it and if not, will skip.

Specification

This module, accepts an object and trys to match keys inside it with environmental variables. So if our object contains {myKey: 'my value'} It looks for MYKEY in env variables and if found, it overwrites the value of that env variable with our object's key. It also has supoort for nested variables and arrays: {myKey: {mySecondKey: 'my value'}} => MYKEY_MYSECONDKEY='my value' {myKey: ['val1', 'val2']} => MYKEY_0='val1' MYKEY_1='val2'
