Can service workers access localStorage?
5 answers. You can’t access localStorage (and also sessionStorage) from a webworker process, the result will be undefined, this is for security reasons. You should use postMessage() to go back to the worker’s source code and have that code store the data in localStorage.
Does IndexedDB work offline?
IndexedDB is provided by the browser and therefore does not need the internet to perform CRUD (Create Read Update Delete) operations.
Can I use the IndexedDB API?
IndexedDB is a way to persistently store data within a user’s browser. Because it allows you to create web applications with rich query capabilities regardless of network availability, your applications can work both online and offline.
What is the difference between service worker and web worker?
Service workers are a proxy between the browser and the network. By intercepting the requests made by the document, service workers can redirect the requests to a cache, allowing offline access. Web workers are general-purpose scripts that allow us to offload processor-intensive work from the main thread.
Is IndexedDB encrypted?

How long is IndexedDB?
