update
Update the addons of your talk installed from slidesk.link.
slidesk update # plugins, components, themes and templates
slidesk update plugins
slidesk update components
slidesk update themes
slidesk update templates
Run it from the directory of your talk. An addon comes from the hub when its name is user__addon: a directory in plugins/, themes/ or templates/, or a components/user__addon.mjs file. The addons you wrote yourself are left as they are.
An addon that cannot be updated is reported, the others are updated anyway, and the command then exits with an error.
A component installed by an older SliDesk is a bare components/addon.mjs, without its author: install it again once with slidesk component install user/addon, and slidesk update picks it up from then on.
