Implementing a jq REPL with fzf

Update: I created jq-zsh-plugin that does this.

One of my favourite tools of my trade is jq. It essentially enables you to process json streams with the same power that sed, awk and grep provide you with for editing line-based formats (csv, tsv, etc.).

Another one of my favourite tools is fzf.

Generic web component HMR

I'm messing around with a generic way to do hot-module-replacement with generic web components whether they be vanilla, or done in a framework like Polymer or Skate.

The idea is that you call hmr(customElementConstructor) in your module files and it will set up the proper hooks.

The const filename should be inserted at build time so that it can remember the original localName of the component for the module.

WTF is "x-layout", "Layout" and "filename"

Setup

Add this to your .profile, .bashrc, .zshrc...

decode_base64_url() {
  local len=$((${#1} % 4))
  local result="$1"
  if [ $len -eq 2 ]; then result="$1"'=='
  elif [ $len -eq 3 ]; then result="$1"'=' 
  fi
 echo "$result" | tr '_-' '/+' | openssl enc -d -base64

	1) Install cloudflared using homebrew:

	brew install cloudflare/cloudflare/cloudflared

	2) Create /usr/local/etc/cloudflared/config.yaml, with the following content

	proxy-dns: true
	proxy-dns-upstream:
	- https://1.1.1.1/dns-query
	- https://1.0.0.1/dns-query
