List of functions in this API grouped by documents object:
export const documents = { ... }.
This API mostly used as helper functions.
total: <T extends Total>(documents: T[]) => numberSimple sum of total in each element - calculates as prices (costs).
shipping: <T extends Shipping>(documents: T[]) => numberSimple sum of shipping in each element - calculates as prices (costs).
total: <
U extends ItemTotal,
T extends Items<U>
>(documents: T[]) => U[]In this list of documents, each element is a list of items.
The function reduces items through all documents, aggregating by id
and accumulates total for each item id.
qty: <
U extends ItemQty,
T extends Items<U>
>(documents: T[]) => U[]In this list of documents, each element is a list of items.
The function reduces items through all documents, aggregating by id
and accumulates qty for each item id.
minus: <
I extends ItemQty & Total,
S extends Items<I>,
P extends ItemQty & Total & Price,
T extends Items<P>
>(from: T[], subtrahend: S[]) => P[]This is the next-order function based on minusItem() from Basics.
This function allows you to do the same, but:
- the minuend is the list of documents (each document is the list of items)
- the subtrahend is the list of items
- function does
minusItem()per each itemidseparately, so takes into account different items
