Basic setup for using Enzyme/Mocha/Chai with create-react-app

This is a temporary solution. Might change in the near future, this depends on how create-react-app will implement testing.

create-react-app quick-test-example

cd quick-test-example

npm run eject

The Problem

Standard practices say no non-root process gets to talk to the Internet on a port less than 1024. How, then, could I get Node talking on port 80 on EC2? (I wanted it to go as fast as possible and use the smallest possible share of my teeny tiny little micro-instance's resources, so proxying through nginx or Apache seemed suboptimal.)

The temptingly easy but ultimately wrong solution:

Alter the port the script talks to from 8000 to 80:

}).listen(80);

Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096

Getting Started

My Usage

I've been using this for several years now, so here are some of the ways I have set it up to be most productive. See my taskrc below for implementation details.

In general, I've had the most success by keeping lists of tasks short and to the point, avoiding the anxiety of seeing 100 tasks and feeling like I'm going to drown.

Installation of NixOS with encrypted root

These are my notes on instaling NixOS 16.03 on a Lenovo ThinkPad X1 Carbon (4th generation) with an encrypted root file system using UEFI.

Most of this is scrambled from the following pages:

	server {
	index index.php;
	set $basepath "/var/www";

	set $domain $host;

	# check one name domain for simple application
	if ($domain ~ "^(.[^.]*)\.dev$") {
	set $domain $1;
	set $rootpath "${domain}";

	#!/bin/bash
	# file: ttfb.sh
	# curl command to check the time to first byte
	# usage
	# 1. ./ttfb.sh "https://google.com"
	# 2. seq 10 \| xargs -Iz ./ttfb.sh "https://google.com"

	curl -o /dev/null \
	-H 'Cache-Control: no-cache' \
	-s \

	/* begin table creation */

	create table department
	(dept_id smallint unsigned not null auto_increment,
	name varchar(20) not null,
	constraint pk_department primary key (dept_id)
	);

	create table branch
	(branch_id smallint unsigned not null auto_increment,

	// Run this in the F12 javascript console in chrome

	// this helps because chrome's network tab's
	// "preserve log" seems to technically preserve the log
	// but you can't actually LOOK at it...
	// also the "replay xhr" feature does not work after reload
	// even if you "preserve log".
