persistenceUtils

Provide various utilities for converting Request/Response objects to JSON.

Methods

(static) buildEndpointKey(request) → {string}

helper function to build endpoint key to register options under. The option contains shredder/unshredder needed for cache to shred/unshredd responses. Ideally, we would like cache to be able to look up such information in the framework based on scope, but there is no central place for such information to reside, considering the facts that the framework should work in service worker case. So the solution is for cache to lookup the information based on request.url, thus we require (1) responseProxy needs to register/unregister the options so during which time period cache is able to look up shredder/unshredder (2) because of asynchronous nature, there could be multiple fetch events going on from the same url, while we don't want the registered shredder/unshredder to grow out of control, we create a unique key so we can use the same key to unreigster the shredder/unshredder (3) any cache operations needs to happen within defaultResponseProxy processRequest scope.
Parameters:
Name Type Description
request Request Request object to build the key for.
Returns:
A unique key that can by used to register option under.
Type
string
