Deploying to Heroku

This guide is for a first-time Rails developer to deploy their app to Heroku, a popular web-hosting service with strong Rails support. This guide assumes you already have a Heroku account and have installed the Heroku Toolbelt.

Make sure you've setup an SSH key for Heroku. Follow this simple guide to create an SSH key and send it to Heroku if needed: Heroku: Managing Your SSH Keys
Navigate into the folder for your Rails app.

Download Image: sdkmanager --install "system-images;android-30;google_atd;arm64-v8a"

	Disclaimer: The instructions are the collective efforts from a few places online.
	Nothing here is my original. But I want to put them together in one place to save people from spending the same time as I did.

	First off, bundle.
	==================

	1. cd to the project directory
	2. Start the react-native packager if not started
	3. Download the bundle to the asset folder:
	curl "http://localhost:8081/index.android.bundle?platform=android" -o "android/app/src/main/assets/index.android.bundle"

	var debug = process.env.NODE_ENV !== "production";
	var webpack = require('webpack');

	module.exports = {
	context: __dirname,
	devtool: debug ? "inline-sourcemap" : null,
	entry: "./js/scripts.js",
	output: {
	path: __dirname + "/js",
	filename: "scripts.min.js"

	# elementary OS post install

	sudo apt update && sudo apt upgrade

	sudo apt install software-properties-common --no-install-recommends
	sudo apt install ubuntu-restricted-extras libavcodec-extra ffmpeg
	sudo apt install firefox vlc
	sudo apt install audacious audacious-plugins
	sudo apt install screenfetch
