NetworkManager
NetworkManager orchestrates asynchronous fetches. By keeping track of all in-flight requests it is able to dedupe identical requests if they are made using the throttle flag.

Members
constructor(dataExpiryLength = 60000, errorExpiryLength = 1000)
Arguments represent the default time (in miliseconds) before a resource is considered 'stale'.
middleware
Consumed Actions
Will initiate network request and then dispatch upon completion.
Processed Actions
Dispatched Actions
allSettled(): Promise
Resolves once all fetches inflight are complete. Conceptually Promise.allSettled
skipLogging(action)
Used by DevtoolsManager to determine whether to log an action
Default:
skipLogging(action: ActionTypes) {
return action.type === FETCH_TYPE && action.meta.key in this.fetched;
}
Protected members
handleFetch(fetchAction)
Called when middleware intercepts 'rest-hooks/fetch' action.
Will then start a promise for a key and potentially start the network fetch.
Uses throttle only when instructed by action meta. This is valuable for ensures mutation requests always go through.
handleReceive(receiveAction)
Called when middleware intercepts a receive action.
Will resolve the promise associated with receive key.
throttle(key, fetch)
Ensures only one request for a given key is in flight at any time
Uses key to either retrieve in-flight promise, or if not create a new promise and call fetch.
getLastReset(): number
Timestamp when entire store was last reset
clear(key)
Clear promise state for a given key
clearAll()
Ensures all promises are completed by rejecting remaining
