Thanks for that one (+your fast response)... it is essentially the same content that is available on the dCloud server as well.
But the samples with client library version 0.0.25 are outdated, because recent 11.6 installations use 0.0.28 and for 12.0 library version 0.0.33 is being shipped.
Changes are small and I can adopt the samples to the new version (+format the minified one).
But probably there's something more "official" available?
