Config

My little project: a config module which aims to focus on making the important parts of environment, and app, configuration [secure,] simple, and easy to use.

[STATUS] Basic basic features A-OK!

Quick Start

Install

 $ npm install @creativefeather/config --save

After installing create the env.js[on] config file in the {project_root}/config directory. Add properties and enjoy!

// env.json || env.js
{
  "development": {}
}

Options

path

By default the module will look in the project root directory for a folder called config. The config path used to search for configuration files can be changed in various ways like so:

// package.json
{
  "name": "my-module",
  "config": {
    "config path": "path/to/config/dir"
  }
}

// In Code (via module)
const config = require('@creativefeather/config');
config({
  use: true,  // option to set module aquired config
  path: "path/to/config/dir"
});

// In Code (before requiring the module)
process.env.CONFIG_OPTION_PATH = 'path/to/config/dir';

// Env Variable
$ CONFIG_OPTION_PATH=path/to/config/dir

env

If no environment is specified, the default will be "development"--however, if there is an environment specified in env.json that begins with 'prod', an error will be thrown instead. If you want to use a different configuration, some ways of specifying it are more practial than others for a typical project. . .

// Environment Variable
$ NODE_ENV=production
// OR
$ CONFIG_OPTION_ENV=production

// In Code (via module)
const config = require('@creativefeather/config');
config({
  use: true,  // option to set module aquired config
  env: "production"
});

// In Code (before requiring the module)
process.env.NODE_ENV = 'production';
// OR
process.env.CONFIG_OPTION_ENV = 'production';

// Env Variable
$ CONFIG_OPTION_ENV=production

Config Files

index.js[on] is where to put default values and values that aren't specific to a particular deployment or sensitive in anyway. It is not required to have this file; but, you should be aware of it for when the need arises.

env.js[on] is where sensitive info and environment specific settings will go. That way, you don't have to commit any of it to the public.

// *** Example Usage ***

// env.js
{
  "all": {
    "db": {
      "username": "cmonster",
      "password": "chocolatechip",
      "host": "localhost",
      "port": 3000
    }
  },

  "development": {
    "logger": new Logger({
      "level": "info"
    }),
    "db": {
      "name": "coolapp"
      "name+TEST": "test"    
    }
  }
}

// index.json
{
  "logger": null
}

If you have more than one configuration in env.js[on], you can put shared values in "all". Properties in the active configuration will override the values in 'all'. Finally, 'env' will be merged with 'index' where 'env' values take priority.
