There's a lack of performant, beautiful, extensible packages to visualize large JSON trees. It'd be nice to see a demo of that.

I totally agree. Firefox's default JSON viewer (an example[0] if u wanna try it with Firefox) is one of the most well-done tools I've come across at solving JSON trees. I wish I could get this as a component to play with in web design

I tracked down the source of Firefox Devtools' JSON viewer.

https://github.com/mozilla/gecko-dev/tree/master/devtools/cl...

It's based on React, but also uses require.js for its dependencies from other parts of Devtools, like TreeView - so it looks tough to separate into an independent component.

I agree. If you want things to perform on the web, you've got to virtualize the rows. Many web libraries don't.
