I am new to angular caching, and while navigating the docs I found that we may use service worker which uses localStorage, and we could use directly the localStorage without the service worker
What is a service worker, and in what scenarios we should use it or avoid using it?
What are the advantages of using service workers besides offline capabilities?
Thanks!
There are tons of document on the subject but to keep it simple : a service worker is a JS script that run in another thread than your main script and can act as a proxy between all your website's calls (ressources, APIs etc...) and your server.
By using a service worker, you can indead cache ressources but also REST responses. To do this, the service worker can cache response into the localStorage as you mentionned : the implementation is up to you.
Depending on what you want to cache, you could cache it directly into the localStorage without the need of a service worker as it is simplier (in a service for example).
