VS Code `launch.json` configurations

VS Code launch.json file serves as a debugging configuration file.

Introduction

Where to put it

It must be stored in PROJET_ROOT/.vscode/launch.json.

Should I commit it?

Though opinions vary, it is not recommended to commit such files in source control. It is specific to every developer, and commiting it would prevent each developer to configure it according to his needs.

Context

AWS Elastic Beanstalk is the Platform As A Service solution by AWS. It is thought as a replacement for Heroku wich is great 🙌 but can become very expensive 💰 when the project is growing or in need of real performance 🏎.

Google App Engine comparison

Google Cloud also has its Platform As A Service product, Google App Engine. However very promising and notably simpler than AWS Elastic Beanstalk, we have been experiencing serious issues while testing it:

downtime in deployment 🚧: when deployong a new version of the app, it often becomes unreachable (5xx errors) for up to a whole minute.
veeeery long deploys ⬆️ ⏲: it takes on average 8 to 10 minutes ⏳ waiting for a new version of the application to deploy. Compared to a few seconds on Heroku and a few minutes on Elastic Beanstalk. We found out that it truly harmed our development wor

Git Pro cheatsheet

Rewriting history

git commit --amend # edit last commit
git commit --amend --no-edit # edit last commit w/o changing commit message

Undoing git stuff

When you make a mistake (e.g. a hard reset to a previous commit, losing important work), you can always undo your changes made with git, even when it seems irrevocaly lost

Workflow

We are using the Github flow, which is mainly:

one master branch that is always production ready and in a deployable state 🛰️
one branch by feature or bug - a.k.a. feature branch
make a Pull Request (PR) on master for your feature / bug fix to be merged and go in production 🚀

No overhead

NGINX

Set up nginx on Mac OS

Installation

Install nginx with Homebrew:

brew install nginx

Start nginx as a brew service:

	# In spec_helper:
	# RSpec.configure do \|config\|
	# ...
	# config.include(MockGeocoder)
	# end
	#
	# In your tests:
	# it 'mock geocoding' do
	# # You may pass additional params to override defaults
	# # (i.e. :coordinates => [10, 20])

	# If you come from bash you might have to change your $PATH.
	# export PATH=$HOME/bin:/usr/local/bin:$PATH

	# Path to your oh-my-zsh installation.
	export ZSH="/Users/nicolasrouanne/.oh-my-zsh"

	# Set name of the theme to load --- if set to "random", it will
	# load a random theme each time oh-my-zsh is loaded, in which case,
	# to know which specific one was loaded, run: echo $RANDOM_THEME
