Particular framework support is implemented via tern plugin.
As there are many frameworks and many plugin developers,
there should be central registry to list them all.
For example I know mostly those started by @angelozerr
https://github.com/angelozerr/tern-liferay
https://github.com/angelozerr/tern-node-express
https://github.com/angelozerr/tern-node-mongoose
https://github.com/Slava/tern-meteor
The best summary currently may be inside TernIDE Eclipse plugin

Plugins can be listed in
- GitHub wiki page
- README (that would required PR to add)
- website (where are sources?)
