Deploy NodeJS Application into EC2 with GitHub actions

This is an experience shared on getting a simple node application deployed into EC2 with github actions.

Create a simple node application

Go the project directory and type the following commands mkdir node-hello && cd node-hello
Type npm init in your terminal to initiate a node project (Make sure you have node installed if not follow the guide here)
Create the index.js file (touch index.js)

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

Design rules

58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

##Golang Type Switch - Arbitrary JSON Array Parsing I'm writing this mostly as a reference for myself. This could also be helpful to people who are new to GO.

####Note 1: Until Problem 3 we will assume we are dealing with a JSON for which we know the data types of key,value pairs. Only in Problem 3 we will look at how Type Switch is used to parse a 100% arbitary JSON

####Note 2: I know the following examples given here can be easily solved by declaring approprite structs and just decoding the PUT JSON into them, but, as im not able to come up with a better scenario, im going to stick with this to explain arbitrary JSON parsing.

	import invariant from "tiny-invariant";

	class AmalgoBox extends HTMLElement {
	get input() {
	return this.querySelector("input") as HTMLInputElement;
	}

	get button() {
	return this.querySelector("button") as HTMLButtonElement;
	}

	use super::hyperlink::Hyperlink;
	use eframe::{egui, epi};
	use egui::{pos2, vec2, Color32, Pos2, Rect, Stroke, Widget};
	use rand::seq::SliceRandom;

	#[derive(Copy, Clone, Debug, PartialEq)]
	enum Player {
	User,
	Computer,
	}

	import { useState } from "react";

	const useLoading = (action) => {
	const [loading, setLoading] = useState(false);

	const doAction = (...args) => {
	setLoading(true);
	return action(...args).finally(() => setLoading(false));
	};

	I was drawn to programming, science, technology and science fiction
	ever since I was a little kid. I can't say it's because I wanted to
	make the world a better place. Not really. I was simply drawn to it
	because I was drawn to it. Writing programs was fun. Figuring out how
	nature works was fascinating. Science fiction felt like a grand
	adventure.

	Then I started a software company and poured every ounce of energy
	into it. It failed. That hurt, but that part is ok. I made a lot of
	mistakes and learned from them. This experience made me much, much

	# Put this function to your .bashrc file.
	# Usage: mv oldfilename
	# If you call mv without the second parameter it will prompt you to edit the filename on command line.
	# Original mv is called when it's called with more than one argument.
	# It's useful when you want to change just a few letters in a long name.

	# - imv from renameutils
	# - Ctrl-W Ctrl-Y Ctrl-Y (cut last word, paste, paste)
