Collections Store

Table of Contents

• Actions
  • receiveCollection( namespace, resourceName, queryString, ids = [], items = [], replace = false )
• Selectors
  • getCollection( namespace, resourceName, query = null, ids=[] )
  • getCollectionHeader( namespace, resourceName, header, query = null, ids = [])

To utilize this store you will import the COLLECTIONS_STORE_KEY in any module referencing it. Assuming @woocommerce/block-data is registered as an external pointing to wc.wcBlocksData you can import the key via:

import { COLLECTIONS_STORE_KEY } from '@woocommerce/block-data';

Actions

receiveCollection( namespace, resourceName, queryString, ids = [], items = [], replace = false )

This will return an action object for the given arguments used in dispatching the collection results to the store.

Note: You should rarely have to dispatch this action directly as it is used by the resolver for the getCollection selector.

argument	type	description
namespace	string	The route namespace for the collection (eg. /wc/blocks)
resourceName	string	The resource name for the collection (eg. products/attributes)
queryString	string	An additional query string to add to the request for the collection. Note, collections are cached by the query string. (eg. '?order=ASC')
ids	array	If the collection route has placeholders for ids, you provide them via this argument in the order of how the placeholders appear in the route
response	Object	An object containing a items property with the collection items from the response (array), and a headers property that is matches the window.Headers interface containing the headers from the response.
replace	boolean	Whether or not to replace any existing items in the store for the given indexes (namespace, resourceName, queryString) if there are already values in the store

Selectors

getCollection( namespace, resourceName, query = null, ids=[] )

This selector will return the collection for the given arguments. It has a sibling resolver, so if the selector has never been resolved, the resolver will make a request to the server for the collection and dispatch results to the store.

argument	type	description
namespace	string	The route namespace for the collection (eg. /wc/blocks)
resourceName	string	The resource name for the collection (eg. products/attributes)
query	Object	The query arguments for the collection. Eg. { order: 'ASC', sortBy: Price }
ids	Array	If the collection route has placeholders for ids you provide the values for those placeholders in this array (in order).

getCollectionHeader( namespace, resourceName, header, query = null, ids = [])

This selector will return a header from the collection response using the given arguments. It has a sibling resolver that will resolve getCollection using the arguments if that has never been resolved.

If the collection has headers but not a matching header for the given header argument, then undefined will be returned.

If the collection does not have any matching headers for the given arguments, then null is returned.

argument	type	description
namespace	string	The route namespace for the collection (eg. /wc/blocks)
resourceName	string	The resource name for the collection (eg. products/attributes)
header	string	The header key for the header.
query	Object	The query arguments for the collection. Eg. { order: 'ASC', sortBy: Price }
ids	Array	If the collection route has placeholders for ids you provide the values for those placeholders in this array (in order).
