Hey, you did a thing and told people [0]! Good for you. Is it perfect? No idea, but from reading the comments here a lot of people don't think so. Who cares though [1]! You're so…

vog on HN> Drawing a card is definitely a GET. I see where you're coming from ("I'm drawing / taking / GETting some cards"), but drawing cards is not an idempotent action. I would…

Not RESTful: uses verbs in URLs and action parameters

alangpierce on HNAs a general rule "action" parameter is pretty non-RESTful. Sometimes RPC-style interfaces like that are ok, but don't pretend that they are RESTful. Also PUTs are supposed to be…

Shuffle randomness and deck id entropy questioned
From 2 comments
This seems like a really cool project! But how are you shuffling the cards, and how are you identifying unique shuffled decks? It looks like the deck_id is 12 characters, numbers…

Support custom deck sizes and card subsets
From 2 comments
Sounds straightforward and simple. Well done. Would like an option to set parameters of a deck. Some card games use only 8 cards from a set and not the whole 13.
carrotleads on HNAdding and subtracting from the starting deck would very useful. Adding Jokers, playing with only 1-10 (scopa), ect

Support multiple players and passing cards

If it supported the idea of multiple players, keeping track of what cards each player has, and facilitating passing cards between players; it could be a cool backend for lots of…

Local random number generator shuffling
From 2 comments
Seriously, why wouldn't you just use a local RNG? Do you realize it's actually less work than reading API documentation?
hurin on HNI like the website design but shuffling cards is extremely trivial to code. Also cards are mostly used for gambling games and it's a huge security hole to use a third party api…
