Query selectors

redux-query provides the following selectors, available from the querySelectors for reading from the queries reducer state:

Selector Name	Return Type	Description
isFinished	boolean	Returns `true` if the query was resolved or cancelled.
isPending	boolean	Returns `true` if the query is in-flight.
status	?number	Response HTTP status code.
lastUpdated	?number	Time at which the query was resolved.
queryCount	number	Number of times a query was started with the same query key.

All of the query selectors have the same signature: the root queries reducer state object as the first parameter and the query config as the second parameter.

Error selectors

If you have the errorsReducer as part of your Redux state, then you can query from the errors state using the provided errorSelectors:

Selector Name	Return Type	Description
responseBody	?any	Parsed response body (if query failed).
responseText	?string	Unparsed response body string (if query failed).
responseHeaders	?{ [key: string]: any }	Response headers (if query failed).

All of the query selectors have the following signature: the root errors reducer state as the first paramater and the query config as the second parameter.
