* first cut - removing an item from cart:
- add actions to cart store for removing an item and keeping track of
pending removal API call
- add reducer logic for storing pending state on an item, and removing
an item
- expose removeCartItem on new useStoreCartItems hook
- hook it up to remove link / trashcan icon in row item
* disable cart quantity picker/remove link while API request in progress:
- expose cart item pending status from store using selector
- use selector to disable quantity related components in line item row
* add typedef for cart items store object provided by hook
* allow user to change quantity of cart items (first cut):
- add action for replacing a cart item in the store
- add generator action for changing quantity
- expose change quantity action on useStoreCartItems hook
- hook up to quantity UI in cart block
(work in progress)
* post-rebase fixes & fix broken typedef:
- rework cart item change quantity callback - now supplies item key like
remove callback
- fix hook StoreCartItem return value typedef - single item with
specified key, was array of all items
- add quantity JSDoc for changeCartItemQuantity action
- remove changeQuantity callback from UI (currently infinite looping)
* fix bug in recieveCartItem reducer - check keys for equality:
- was key === object
* fix invalid url in POST cart/items/quantity request
* hook up cart line item quantity to API:
- remove internal state/ref for QuantitySelector, is now a controlled
component
- call changeQuantity action from QuantitySelector change callback
* QuantitySelector no longer needs a ref to wrangle number input value
* hoist quantity state out of QuantitySelector into story (fix storybook)
* add product sold_individually option to cart item API response
* limit sold_individually items to 1 per cart/order:
- support optional max value in QuantitySelector
- set maximum dependent on sold_individually API field
* prevent user from requesting zero x cart item (API 500 errors):
- add minimum limit to QuantitySelector
- default limit to 1
+ fix bug with limiting to maximum value in number input change handler
* remove useStoreCartItems, zombie hook coming back from rebase 🧟♂️
* address various review feedback:
- inline undefined check, don't use lodash
- quantityInputOnKeyDown callback hook depends on canIncrease/canDecrease
- also removed undefined check for minimum, as minimum has default 0
* use safer typeof check for presence of maximum prop
