configstore 
Easily load and persist config without having to think about where and how
The config is stored in a JSON file located in $XDG_CONFIG_HOME or ~/.config.
Example: ~/.config/configstore/some-id.json
If you need this for Electron, check out electron-store instead.
And check out conf for an updated approach to this concept.
Install
$ npm install configstore
Usage
const Configstore = require('configstore');
const packageJson = require('./package.json');
// Create a Configstore instance
const config = new Configstore(packageJson.name, {foo: 'bar'});
console.log(config.get('foo'));
//=> 'bar'
config.set('awesome', true);
console.log(config.get('awesome'));
//=> true
// Use dot-notation to access nested properties
config.set('bar.baz', true);
console.log(config.get('bar'));
//=> {baz: true}
config.delete('awesome');
console.log(config.get('awesome'));
//=> undefined
API
Configstore(packageName, defaults?, options?)
Returns a new instance.
packageName
Type: string
Name of your package.
defaults
Type: object
Default config.
options
Type: object
globalConfigPath
Type: boolean
Default: false
Store the config at $CONFIG/package-name/config.json instead of the default $CONFIG/configstore/package-name.json. This is not recommended as you might end up conflicting with other tools, rendering the "without having to think" idea moot.
configPath
Type: string
Default: Automatic
Please don't use this option unless absolutely necessary and you know what you're doing.
Set the path of the config file. Overrides the packageName and globalConfigPath options.
Instance
You can use dot-notation in a key to access nested properties.
.set(key, value)
Set an item.
.set(object)
Set multiple items at once.
.get(key)
Get an item.
.has(key)
Check if an item exists.
.delete(key)
Delete an item.
.clear()
Delete all items.
.size
Get the item count.
.path
Get the path to the config file. Can be used to show the user where the config file is located or even better open it for them.
.all
Get all the config as an object or replace the current config with an object:
config.all = {
hello: 'world'
};
