Suggested new section: Task based Guide (to supplement faq)

[Neon22]

In some systems this might be the Faq and the current faq might be a series of guides or recipes.

Anyway the section might look like this:

I really like this approach and wondering if @ntoll shares the same feeling

[ntoll]

Yup. Working on it.

More:

Your worker only runs once.

• you are probably missing an await before calling it, and/or an async on the calling function

[Neon22]

For workers we now appear to have a number of choices - the use cases of which are not exactly clear:

You want to load (fetch) a file from a remote url resource:
 - use a service worker
 - https://docs.pyscript.net/2025.3.1/user-guide/workers/#option-2-service-worker-attribute
 - example 

[Neon22]

Also:
localStorage and sessionStorage are referred to as "Web Storage" and are disabled by some browsers(e.g. Firefox) when setting "disable third party cookies".
localstorage and Sessionstorage are synchronous and so the code waits for them to be accessed.

An async mechanism that performs the same objective and is not blocked by "third party cookie" settings is the "IndexedDB" storage. This is also available in Workers. Pyscript accesses this under pyscript.storage
It is documented for pyscript here: https://docs.pyscript.net/2025.3.1/api/#pyscriptstorage
This interface is synchronous and does async internally. (A write can be awaited).

[Neon22]

Can't emphasize this one enough:

Using fs.mount and system popup says: "Unable to grant access" and/or the Javascript console reports:
"Failed to execute 'showDirectoryPicker' on 'Window': Cross origin sub frames aren't allowed to show a file picker."

• You cannot test the fs.mount() filesystem storage in chrome from the editor page. It contains an iframe and this operation is forbidden from within an iframe. If you are on pyscript.com - click the "Visit Site" link to open the app on its own page.
• The fs.mount operation should then run.
