Fable Settings

A very simple, tolerant settings loading library.

Why

It became tiring to see a heap of boilerplate config file/defaults loading at the top of microservices and the like.

How

Install it with npm.

$ npm install fable-settings

Fire it up and access some settings:

var settings = require('fable-settings').new({Product: 'SomeProduct', Version: '9.10.11'});
console.log('My product: '+settings.settings.Product);
console.log('My version: '+settings.settings.Version);

Wanna get tricky? Load settings from JSON:

var settings = require('fable-settings').new({Product: 'SomeProduct', Version: '9.10.11', ConfigFile: '/home/strongbad/config.json'});

Or even merge settings in later:

var settings = require('fable-settings').new({Product: 'SomeProduct', Version: '9.10.11'});
console.log('My product: '+settings.settings.Product);
console.log('My version: '+settings.settings.Version);
settings.merge({FavoriteTool:'Slap Chop'});
console.log('My Favorite Tool: '+settings.settings.FavoriteTool);

Unit Testing

You can run the unit tests by executing:

$ npm test

Or you can get the istanbul coverage report by executing:

$ npm run coverage
