A simple, dependency-free configuration helper with a nano API.

var config = require('nano-config')('./my-configuration.json');
config.greet = 'world';
config.save()

Loads my-configuration.json. If it doesn't exist it will be created when you call save.

{
  "greet": "world"
}

Okay, cool. You just saved some JSON. Who cares?

You only need to load a configuration file once. Here's some other part of your application.

var config = require('nano-config');
console.log(`hello ${config.greet}`);

Outputs

hello world

nano-config remembers the last config you loaded.

nano-config doesn't depend on any modules, doesn't care about environment variables and doesn't have a verbose API.

Do you need to load a specific configuration file for a specific environment? Do it yourself.

var config = require('nano-config')(`./${process.env.NODE_ENV}.json`)

Custom serialization. Prefer CSON?

var CSON = require('cson');
var config = require('nano-config');
config.deserialize = str => CSON.parseSync(str);
config.serialize = obj => CSON.stringifySync(obj);
config('./my-config.cson');

Loads a configuration file.

Saves the current configuration to file. Optional callback is called when save is finished.

The object serializer. It takes an object and returns a string.

The string deserializer. It takes a string and returns an object.
