dev is strange

full-stack learning path
react framework, codecademy
project "jammming" - basic app

front-end going great
everything just works

it's back-end time!

Spotify API, auth, access token, callback
wrong redirect uri, it doesn't work
correct uri but it's localhost, it doesn't work
ngrok http 3000, it doesn't work
deployed on vercel, it doesn't work
missing a trailing slash (fuck! now i can feel it),
it's … still not work
correct uri, with trailing slash, it doesn't work

got frustrated and quit
then coming back after a while,

it works!
wtf i don't get it
it works!!

so things take time
and it works!!!
