Hi Paul,
welcome to the list :)
I tried to take a look at the feature, but when I try to load the shelf
browser, it remains empty or takes a long while to load. There are some
errors in the console (mostly CORS Missing Allow Origin) that could
relate to the problem.
Maybe adding a visual indicator about the content still loading could be
a nice addition.
I quite like the idea of generating a nice replacement picture for
missing covers.
Hope this helps,
Katrin

Hi everyone,
I developed a replacement for the koha shelf-browser realised as a
JavaScript library which is already in production with one of our clients.
tcohen asked me to provide necessary infos and resources so others can
take a look.
* The most important part is LMSCoverFlow.js
<https://github.com/LMSCloud/Koha-LMSCloud/blob/master/koha-tmpl/opac-tmpl/bootstrap/js/LMSCoverFlow.js>
which
is the library itself.
* For the actual function calls take a look at opac-detail.tt
<https://github.com/LMSCloud/Koha-LMSCloud/blob/master/koha-tmpl/opac-tmpl/bootstrap/en/modules/opac-detail.tt>
starting
at line 1710.
* The shelf-browser functionality depends on some scripts, namely
coverflowbyshelfitem
<https://github.com/LMSCloud/Koha-LMSCloud/blob/master/opac/svc/coverflowbyshelfitem>
and
covergen
<https://github.com/LMSCloud/Koha-LMSCloud/blob/master/opac/svc/covergen>
* The corresponding modules are CoverFlowData.pm
<https://github.com/LMSCloud/Koha-LMSCloud/blob/master/C4/CoverFlowData.pm>
and
CoverGen.pm
<https://github.com/LMSCloud/Koha-LMSCloud/blob/master/C4/CoverGen.pm>.
I already got lectured on not putting stuff in C4. Next goal is to
move everything data related to an API endpoint.
The js is actually written in TypeScript using ES6 modules and I will
change the visibility of the corresponding repo soon and notify you
accordingly.
Since the shelf browser is based on itemcallnumbers, it is necessary
to assign such to a sufficient amount of titles (9 when I tested on
koha-testing-docker).
To see how it looks in prod take a look at this OPAC
<https://sb-heilbronn.lmscloud.net/>.
If my explanation is not sufficient or I should have forgotten
something, you can send me a mail or write to me on IRC. My nick is
paulderscheid.
I’d love to get feedback and I’m open to criticism.
Kind Regards.
Paul
