React-native Android Facebook login implementation

Many thanks to @satya164 and this thread for getting things moving.

##Setup your app on Facebook

• The quickstart is the best way to get everything you need (keys, hashes etc). Make sure to generate your Key Hash or else login will not work! https://developers.facebook.com/quickstarts/?platform=android

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

// === Arrays

var [a, b] = [1, 2];
console.log(a, b);
//=> 1 2


// Use from functions, only select from pattern
var foo = () => [1, 2, 3];

Lets say we have YoloFont.otf 

1. We add it to vendor/assets/fonts/ folder
2. Me personaly creates a file named fonts.css.scss in app/assets/stylesheets

In it I have 

@font-face{
    font-family: 'YoloFont';

agnoster.zsh-theme

A ZSH theme optimized for people who use:

• Solarized
• Git
• Unicode-compatible fonts and terminals (I use iTerm2 + Menlo)

For Mac users, I highly recommend iTerm 2 + Solarized Dark
