Not specifically for the registry, but when you access it with RegTAP I 
guess you could use

- André Schaff et al's code presented in 2016 at Trieste: 
https://gitlab.com/cdsdevcorner/votable.js along with your own TAP 
transaction code (for example written with jQuery)
- Jean-Christophe Malapert and Thomas Rolling's code which seem to 
handle TAP https://github.com/malapert/JsVotable (I haven't tested it)

I'll let those authors please comment about the status of their 
software. In my current projects, I found more convenient to rely on the 
robust pyvo.registry implementation on the server-side with Django. In 
the browser, it might also be doable with interesting modern solutions 
such as PyScript (https://pyscript.net/) ?
