Defur

Version: 0.2.0
Master build:
Develop build:

This library makes it easy to defer the construction or execution of a service until it's needed.
It can be installed in whichever way you prefer, but I recommend NPM.

Basic usage

var defur = require('defur');
var http = require('http'); // Just using HTTP as an example
var services = {

    // Define the service inline...
    get server() {
        return defur('server', this, function() {
            return http.createServer().listen(3000);
        });
    }

};

// ...or define the service later
defur.define('server', this, function() {
    return http.createServer().listen(3000);
});

// Use the service
services.server.on('request', function() {});

// Service is only created once
services.server === services.server // true
