config-persistence

This module helps you persist configuration in a Redis database. Read the example below to understand the motivations.

Install

	npm install config-persistance

Example

If you need to boot a node.js application with some default values, but then an administration needs to change those values without rebooting the whole application, this module helps you save your configuration in Redis.

Use

	var db = 2;
	var options = {
		port: 6379,
		host: "localhost"
	}

	var config = new Config(db, options);
	var settings = {
		foo: "bar"
	}
	
	config.init(settings); // initialize with events

	config.on("initialized", function(settings) {
		// do something with the values
	});

	// change the values
	config.set("foo", "Foo is not bar anymore");

	config.on("set:foo", function(value) {
		console.log("Use the name of the key as the event and then get the value");
	});

	config.get("foo", function(err, value) {
		// get the value of foo
	});

	config.get("foo")
	.then(function(value) {
		console.log("Works with promises too");
	})
	.fail(function(err) {
		console.log(err);
	});
