pc guru: I got a mail from a friend; who wanted me to join the team on NodeJS Development; let's leave the full details anyway; i explained not being around and advised to look around in Nigeria online for Node Devs; and he complained about almost "Non-availability" compared to PHP; my question are there much devs in Nigeria considering NodeJS and if not; why because NodeJS is the lighter and less resource intensive option to PHP. A number of startups are looking at NodeJS; and is there anyway we can create a NodeJS awareness and adoption on NL. Because having played with it; its really something else

pc guru: oh well if its okay just let me know if not; i will just advise you buy the books and we continue from there, but first anyone with prior experience on Node before we start

Ajibel: @pc guru, what fascinates you about node.js I was also introduced to it via worldbest last year buh it didn't tickle my fancy after downloading and going thro' it a bit :-/

greenPHP: I am following?
Hitting us with node again when your head is full of javascript and PHP @ PC guru.
Hoping to do nodes someday.

//PHP
$file_get_content('porn.flv');
echo "Hello";
//Hello Here prints after file has been loaded

//NodeJS
(require('fs')).readFile('porn.flv',function(){console.log('Done')});
consoel.log('Hello');
//Hello Prints first before the file has been loaded which brings us to two concepts 

myWebService.get("http://www.example.com")
    .then(function(result) { 
        return myDb.add(result); 
    })
    .then(function() {
        console.log('data successfully saved');
    }, function(error) {
        console.log('an error occurred while saving:');
        console.dir(error);
    });

function loadData() {
    var urls = [
        'http://www.example.com/',
        'http://www.example.org/',
        'http://www.example.net'
        ];
        
    var promises = urls.map(function (url) {
        return myWebService.get(url);
    });

CODE-EATER:
When I learn this thing,m gona create something massive with it...d idea is fully ready, jst missing the knowledge

pc guru:

You know JavaScript ? if yes send me your mail, there's a book i can send to you, read it and in 2 days i could get the underlying concept frm it, its striaght to the point

CODE-EATER:

Yea...to an intermediate level.... As 4 my mail,mail me tru NL mail,I dont want to post it publicly

// package/lib is a dependency we require
var lib = require('package/lib');
 
// some behaviour for our module
function foo(){
    lib.log('hello world!');
}
 
// export (expose) foo to other modules
exports.foo = foo;

function Util(){

this.log=function(){
console.log('Logged');
}
}

module.exports=new Util;

function Util(){

this.log=function(){
console.log("Logged');
}
}

return new Util();

module.exports.debug=new Util;

lib.debug.log();

pc guru:

module.exports.debug=new Util;

Rename this means to access this it becomes

lib.debug.log();

For now try this out and practice before moving forward also i'd like some feedback i feel am writing this for myself

curiouslad:

You lost me after promises

pc guru:

A Promise is an Object that holds the result of an async task e.g when you run an Ajax in Jquery there is a success and function however in Promise, its an Object that has two aspect the error the success and the then, error when an error triggers and success when the result is ok, the then will run regardless of the two state its the last method, also there's a Whenable Object it takes a Promise, meaning when the promise has been resolved it calls. in short words it contains result of async tasks

curiouslad:

I do understand promises - via angularJs.
You lost me at the commonJs, reading up on it though. Might have to actually delve into nodeJs

pc guru:

sorry i have that bad habit of not explaining why, CommonJs is just a spec that allows JavaScript to be in Packages just like java, that's the best definition. Sure no problem, am curious how is AngularJS am more of Dojotoolkit Fanatic and never bothered to touch any other JS Framework except jquery(which i hate).

curiouslad:

AngularJs is cool, easy to start with, can be tough to wrap the head around uphill but definitely worth it. It actually implements its own jQlite version of jQuery.

Angular is modular and implements dependency injection, so i can inject modules/libs where needed at runtime rather than 'require'ing them.

Still following this page though
