Whether you use 2 spaces or 4 spaces, there are a few simple things that can make your node.js code easier to read. We've been using them in all the hapi modules for over 4 years now to great results. This list is by no means complete but it highlights the most useful elements that will give you immediate value in reducing bugs.

Required modules

JavaScript makes it harder than most languages to know where variables are coming from. Variables assigned required modules are particularly important because they represent a singleton object shared with the entire application. There are also globals and module globals, along with function variables and arguments.

Traditionally, variables starting with an uppercase letter represent a class that must be instantiated using new. This was an important semantic in the early days of JavaScript but at this point, if you don't know Date requires new Date() you are probably very new. We have adopted Upper Camel Case variable names for all module global variables

Local SSL websites on Mac OSX

These instructions will guide you through the process of setting up local, trusted websites on your own computer.

These instructions are intended to be used on Mac OSX Yosemite.

NOTE: You may substitute the edit command for nano, vim, or whatever the editor of your choice is. Personally, I forward edit to Sublime Text:

alias edit="/Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl"

A versão do Nginx disponível nos repositórios oficiais do Ubuntu 12.04 é a 1.1.19, mas queremos a usar a versão estável atual, então vamos adicionar o repositório PPA oficial do Nginx ao nosso VPS. Para isso, digite o seguinte comando no terminal:

nano /etc/apt/sources.list
Com o arquivo de repositórios aberto, navegue até o final do arquivo com as setas de direção do seu teclado e adicione a linha abaixo:

deb http://ppa.launchpad.net/nginx/stable/ubuntu precise main

Adicione o repositório PPA do Nginx no final do arquivo sources.list

Feito isso, aperte <Ctrl + O> para salvar e <Ctrl + X> para fechar o arquivo e voltar ao terminal. Agora ainda com o terminal aberto, vamos adicionar a chave de autentificação do PPA, atualizar a lista de repositórios e atualizar o sistema todo. Copie e cole os comandos abaixo, lembrando de dar enter ao final de cada linha:
