Getting Started with Node.js: Hello World

12/28/2015

This is a basic tutorial for how to get started with Node.js and run node javascript files.

Text Editor

There are really no fancy IDE's for Javascript. A nice Javacscript editor that I like is Sublime Text 2.

Hello Command Line

If you want to use Node.js then you should get used to the command line. Node is meant to run on servers, and most servers are accessed through command line. But you don't need any special programs for that. You can use terminal on mac or run cmd on windows. You should get used to working in command line since you'll be using it a lot working with Node.js. you'll need to get the actual executable file called node that you can run in order to run a javascript file as a node file.
First, you'll have to download the node exectuable.

Beware of the If-Semicolon Bugs!

This has happened to me enough times before for me to be embarrassed by it, and for that reason I'm writing this blog post about it. If you have an if statement that is always returning true (it feels something like, "GAAAHH, why does my if statement always return true!) then this could be your problem (and solution!). I noticed this mistake again today working in Actionscript 3 while fixing a bug in Head Exploder. Here's a simplified version of the as3 code:

var smallNumber:Number = 1;
var bigNumber:Number = 100;

if (smallNumber > bigNumber)
{
     trace("Uh oh!");
}

In an early example in Martin Fowler's book Refactoring: Improving the Design of Existing Code he highlights that renaming a variable or method is a legitimate form of refactoring. It can also be immensely helpful to the readability if the code. Here's an except from page 15 of the book:
