Different zoomlevels Mobile and Desktop

[vvmruder]

Hi

I was trying several things. But can't achieve what I wanted, so I ask here.

Problem:
Initial zoom level (extent+scales) of a Theme is defined once in the themes.json. The application starts well on the right extent. On desktop theme content is centered and zoomed well. On mobile devices (small screen) the application shows a small part of the map because the extent and max zoom level does not allow anything else. It would be nice to see the whole extent of the theme also on mobile. But this would mean to have a really zoomed out behavior on desktop. This is also connected to the home button which brings back the initial view.

Questions:

1. Is there a solution already which I don't see?
2. Could we think about offering different configs for mobile and desktop? At least regarding to the zoom levels?

Thank you for having a look.

Regards
Clemens

Hi @vvmruder

Is there a solution already which I don't see?
I also have this question

At the moment I can see it can be overcome using the following method, which may be useful to you/others:

Important parameters for zoom:

"c" is for coordinates, e.g: c=-514492%2C6497455
Note: "%2C" is a space in urlencoding.

"s" is for scale.

Important url parameters for zoom:

"c" is for coordinates, e.g: c=-514492%2C6497455
Note: "%2C" is a space in urlencoding.

"s" is for scale.

There's also preserveExtentOnThemeSwitch

If there's better ways I'm also missing please feel free to correct me
