Configs

Zero configuration config module. Simply require the module and your project's config files will be loaded and merged together.

A default configuration file is looked for and loaded first, followed by an environment level config file, based on NODE_ENV. Lastly a local config file is loaded. All configuration files are recursively extended into any previously loaded file.

Both .js and .json extentions will be loaded.

The local file is the last on the list to give you the flexibility of having per user configs, this file is generally included in your .gitignore to provide flexibility on the end developer. This could also be used as part of a deployment strategy if you don't want to rely on NODE_ENV based settings. Simply copy or
move the file you want, lets say config/production.json, into config/local.json to ensure the correct app configuration reguardless of your environment variables.

Why?

There are plenty of other configuration modules out there, so why another one? I wanted a config module that I didn't have to configure, with many others you will end up including the module, telling it where your files live, and / or providing it defaults. You might just end up with a config.js file as a wrapper to the module of your choosing, too much work I say! This is meant to be an extremely simple way of configuring your app, all while having a local config in mind, which can be very useful when a team is working on the same project.

Usage

var config = require('configs')

Config files will be be loaded with the following pattern, pathing is relative to the project root directory. The project root directory is found by following the module.parent recursively until there either is no more parents or a package.json file is found.

Directory based:

• ./config/default.json
• ./config/{NODE_ENV}.json
• ./config/local.json

File based:

• ./config.json
• ./config.local.json
• ./config.{NODE_ENV}.json

Example

Seperate file configurations

In ./config/default.json:

{
  "debug": false
, "database": {
    "host": "localhost"
  , "port": 6379
  , "user": "paul"
  }
}

In ./config/local.json:

{
  "debug": true
, "database": {
    "port": 11212
  }
}

End result: require('configs')

{
  "debug": true
, "database": {
    "host": "localhost"
  , "port": 11212
  , "user": "paul"
  }
}

Single file configuration

If only a single configuration file is found, the module will check for a property matching the current NODE_ENV and extend it into the base config.

In ./config.json

{
  "something": true
, "sea": {
    "lab": 2021
  }
, "production": {
    "something": false
  , "hey": "there"
  }
}

With NODE_ENV=production, require('configs')

  "something": false
, "hey": "there"
, "sea": {
    "lab": 2021
  }
, "production": {
    "something": false
  , "hey": "there"
  }
}

Debug

If a debug property is found after all files have been loaded, the module will output the file paths of everything that was loaded.

package.json

If a package.json is found within the root directory, the version property will be added to the config. The module will also check for a config property that can be used to specify the directory in which the files are located. Defaults to ./config

Install

With npm

npm install configs
