** Hook for getting and updating items in the Context. | ||
** GroupName and urlKey are defined in the hook where the useApiRequest hook is called. | ||
EXAMPLE: | ||
export const useSuggestions = (itineraryId: number, options?: Options) => { | ||
const handleError = useErrorHandler() | ||
return useApiRequest<{ cases: Case[] }>({ | ||
...options, | ||
url: makeGatewayUrl([ "itineraries", itineraryId, "suggestions" ]), | ||
groupName: "suggestions", | ||
handleError, | ||
isProtected: true | ||
}) | ||
} | ||
CORRECT: | ||
const { getContextItem, updateContextItem } = useContextCache("suggestions", makeGatewayUrl([ "itineraries", itineraryId, "suggestions" ])) | ||
*/ | ||
