kandi X-RAY | async-local-storage Summary
This is a p(r)ollyfill for a fully-async object-storage API that’s simpler than [IndexedDB] but also async, removing many of the [performance hazards of localStorage] The API is roughly mirrors the [ES6 Map type] but all methods return [Future] instances to enable async operation. To get started quickly, use one of the pre-built versions from the [bin/ directory] To work from source, make sure you git submodule update --init after cloning.

QUESTION
I'm trying to get cookie or localStorage value in my API request. When I'm trying to access localStorage I get error that localStorage is not defined, cookies are undefined, I tried my luck with AsyncLocalStorage, but I'm getting error that window is undefined. There is any way to get saved value in this asynchronous function?

Answered 2020-Oct-27 at 20:51This is expected. When you process the data in your API it is actually running in the server. Localstorage, and cookies however are browser based storage (This is also why window is undefined, servers don't have windows). As a result they are not available to the API to leverage. Instead when you make the API request you need to add the data into a header which can then be parsed on your server.
Setting a header on your request: https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/setRequestHeader
From there you should be able to read the headers through:
