In the default React Native app scaffolding you have to edit AppDelegate.m to change where it loads the code if you want to test on your device. I use the following snippet to detect if it's being compiled for Debug or Production and for the Simulator or a device. For Production it uses a copy of the code included in the bundle, for Debug on the simualtor it loads from a server on localhost and for Debug on a device it loads from a server on a given IP address.

NOTE: You need to edit YOUR-IP-HERE and change it to the IP to load the code from when in Debug mode on a device. You could use a service like ngrok to make this work from anywhere.

  NSURL *jsCodeLocation;

  // Loading JavaScript code
  #if DEBUG
    // For Debug build load from development server. Start the server from the repository root:

Exponent - ex-navigation

This is for now, for my personal use only, things might not be correctly explained here. For the official docs please check: https://github.com/exponentjs/ex-navigation/blob/master/README.md

Navigation bar configuration

On every screen you can use the built-in navigation bar, you can add a title, left button, right button or change navigation bar’s style. All you need to do is pass appropriate params to navigationBar in the route configuration:

import React, { Component } from 'react';

Laravel's Dependency Injection Container in Depth

Translations: Korean (by Yongwoo Lee)

Laravel has a powerful Inversion of Control (IoC) / Dependency Injection (DI) Container. Unfortunately the official documentation doesn't cover all of the available functionality, so I decided to experiment with it and document it for myself. The following is based on Laravel 5.4.26 - other versions may vary.

Introduction to Dependency Injection

I won't attempt to explain the principles behind DI / IoC here - if you're not familiar with them you might want to read What is Dependency Injection? by Fabien Potencier (creator of the Symfony framework).

	# Bash script to install latest version of ffmpeg and its dependencies on Ubuntu 12.04 or 14.04
	# Inspired from https://gist.github.com/faleev/3435377

	# Remove any existing packages:
	sudo apt-get -y remove ffmpeg x264 libav-tools libvpx-dev libx264-dev

	# Get the dependencies (Ubuntu Server or headless users):
	sudo apt-get update

	mkdir -p generated

	const promisify = fn => new Promise((res, rej) => {
	const done = (err, val) => (err ? rej(err) : res(val));
