defur

Defer construction of a service until it is needed.

Defur

Version: 0.2.0
Master build: [![Master branch build status][travis-master]][travis]
Develop build: [![Develop branch build status][travis-develop]][travis]

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][npm].

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 

I accept contributions to the source via Pull Request, but passing unit tests must be included before it will be considered for merge.
