Improve your curl with pretty formmated json responses

requirements node.js

add in your .zshrc

[[ -s $HOME/bin/prettycurl.sh ]] && . $HOME/bin/prettycurl.sh

• if you don't have, then create a $HOME/bin dir
• put the pretty-json and prettycurl.sh in $HOME/bin and add execution permission in both of them

execute this command, to apply changes:
