Deploying the Joplin Web client on NAS

Excuse me, is there any way to deploy the Joplin Web client on NAS? thanks

Could you please clarify what you mean by "Joplin Web Client"?

Is there a way to access/edit notes in Joplin Server through web pages?

No.

A user did create a project to try to make a web version of Joplin but this was archived a couple of years ago.
