Setup a Node.js project with Typescript, ESLint, Prettier, Husky

Starting a personal node project could be easy; starting a team node project could be challenging.

I am a developer currently working in SEEK Australia.

In my experience, common mistakes developer make when starting a projects are:

No Linting

Conventional Commit Messages

See how a minor change to your commit message style can make a difference.

Tip

Take a look at git-conventional-commits , a CLI util to ensure these conventions, determine version and generate changelogs

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

Before upgrading, make sure you are allowing insecure registry access, or your newer docker won't be able to talk to the Deis registry:

sudo bash -c 'mkdir -p /etc/systemd/system/docker.service.d/; cat <<EOF > /etc/systemd/system/docker.service.d/50-insecure-registry.conf
[Service]
Environment="DOCKER_OPTS=--insecure-registry 10.0.0.0/8 --insecure-registry 172.16.0.0/12 --insecure-registry 192.168.0.0/16"

	# Preloading usually required an extra query.
	# To do it in one query, a `join` is needed, and the call to `preload` needs to know the name of join
	# This macro does both the `join` and `preload` together
	defmodule Preloader do
	import Ecto, only: [assoc: 2]
	alias Ecto.Query.Builder.{Join, Preload}

	defmacro preload_join(query, association) do
	expr = quote do: assoc(l, unquote(association))
	binding = quote do: [l]
