feathers-configuration

A small configuration module for your Feathers application.

About

feathers-configuration allows you to load default and environment specific JSON configuration files and environment variables and set them on your application. Here is what it does:

• Given a root and configuration path load a default.json in that path
• When the NODE_ENV is not development, also try to load <NODE_ENV>.json in that path and merge both configurations
• Go through each configuration value and sets it on the application (via app.set(name, value)).
  • If the value is a valid environment variable (e.v. NODE_ENV), use its value instead
  • If the value start with ./ or ../ turn it it an absolute path relative to the configuration file path

Usage

The feathers-configuration module is an app configuration function that takes a root directory (usually something like __dirname in your application) and the configuration folder (set to config by default):

import feathers from 'feathers';
import configuration from 'feathers-configuration';

// Use the current folder as the root and look configuration up in `settings`
let app = feathers().configure(configuration(__dirname, 'settings'))

Example

In config/default.json we want to use the local development environment and default MongoDB connection string:

{
  "frontend": "../public",
  "host": "localhost",
  "port": 3030,
  "mongodb": "mongodb://localhost:27017/myapp",
  "templates": "../templates"
}

In config/production.js we are going to use environment variables (e.g. set by Heroku) and use public/dist to load the frontend production build:

{
  "frontend": "./public/dist",
  "host": "myapp.com",
  "port": "PORT",
  "mongodb": "MONGOHQ_URL"
}

Now it can be used in our app.js like this:

import feathers from 'feathers';
import configuration from 'feathers-configuration';

let app = feathers()
  .configure(configuration(__dirname));

console.log(app.get('frontend'));
console.log(app.get('host'));
console.log(app.get('port'));
console.log(app.get('mongodb'));
console.log(app.get('templates'));

If you now run

node app
// -> path/to/app/public
// -> localhost
// -> 3030
// -> mongodb://localhost:27017/myapp
// -> path/to/templates

Or with a different environment and variables:

PORT=8080 MONGOHQ_URL=mongodb://localhost:27017/production NODE_ENV=production node app
// -> path/to/app/public/dist
// -> myapp.com
// -> 8080
// -> mongodb://localhost:27017/production
// -> path/to/templates
