[Interop-dev] netjson for meshviewer

[Nemesis]

Super cool!

Would it be possible to feed to it data from external APIs?

For example:
https://openwisp.nnxx.ninux.org/api/topology/b079ba15-0009-4d4d-9d61-73b85c6c91f1/

To disable the HTML browsable API use this:
https://openwisp.nnxx.ninux.org/api/topology/b079ba15-0009-4d4d-9d61-73b85c6c91f1/?format=json

This type of backend implementation is open source:
