node-config-files

node-config-files

While working on any Node project we often face the problem when we need to manage our configuration files based on environments. For instance, most well known environments are development, test and production. And we not limited by them, right!? Projects can have non-standard environment names and for each of them we want sleek and straight forward way of how we manage its configuration files. Here is why node-config-files can come in handy.

Scaffolding

By default node-config-file looks for config folder within the root of our project folder. And, it expects a file structure of this folder to be flat. In other words, node-config-files doesn't support subfolders.

Default

<project_root>/config/*

NOTE: If you prefer to keep our configuration files in different folder, you should specify its path explicitly. See example

File naming

There are rules of how you name your configuration files in order to make them work with node-config-files module.

A file name should follow the pattern: [section].[environment].config.js

Where:

• section - A property name in a global config object.
• environment - An environment name in which this configuration will be available.

Here examples of valid configuration file names:

• project.config.js
• database.development.config.js
• rest_api.production.config.js

For files that do not belong to any environment its content will be available over property common in global config object, and for files that do its content available over property env.

Getting started

Install

To install the module run following command in your project folder.

npm i node-config-files --save

Configure

Create a folder where you are going to store configuration files for your applicaiton.

mkdir config

Once folder is created you can start add you configuration files to it.

NOTE: By default this module looks at config folder in the root of your application. But this behaviour can be overridden.

Examples

For more detailed example please see tests

Common use case

/*
	Assume we have following config files
	./config/project.config.js
	./database/database.development.config.js
*/

const config = require('node-config-files')();

config.common.project; // project.config.js
config.env.database;   // database.development.config.js

Custom configuration folder path

const config = require('node-config-files')(
	'./server/config',
	{
	  debug: true,
	  NODE_ENV: 'test'
	}
);

NOTE: Make sure that your path is relative to your project root folder.

Options

• options.debug - Shows errors in the console, if any. (default: false)
• options.NODE_ENV - Allows you to override process.env.NODE_ENV. (default: development)

Global config object

This is a common object which will be returned once node-config-files module is invoked.

{
	"common": {},
	"env": {},
	"packageConfig": {}
}

config.common

Contains the content of files which are environment independent.

config.env

Contains the content of files which are environment dependent.

config.packageConfig

Contains properties which were defined in package.json file.

NOTE: Properties dependencies and devDependencies are not included.
