Vyvern Bridge
by Vyvern
Vyvern Bridge is the shared foundation library that other Vyvern mods build on, providing a common hub, permissions and config sync for NeoForge on 1.21.1.
What it does
Vyvern Bridge supplies pieces that several companion mods reuse, so each one does not carry its own copy. Server operators can manage a single, consistent permission model rather than a separate scheme for each mod, because the included permission-node framework covers them all, and a config sync layer keeps settings matched between the server and its players. The mod is required by 5 other mods, including Vyvern Mine, Vyvern Teams, Vyvern Stats, Vyvern Autopilot and Vyvern QOL, so those mods need it installed alongside them.
The in-game hub is a GUI shell with a custom translucent Vyvern-styled tab rail, and the panels of the other Vyvern mods are built into it. An optional WebSocket bus can connect the hub to a Vyvern panel for remote management, and that connection is dormant unless it is configured. Without configuration nothing breaks and nothing phones home. Vyvern Bridge runs on client and server and targets NeoForge for 1.21.1 only, with the 0.1.0 build as the latest file, released under a custom license that is not open source.
Key features
Permission-node framework
A shared permission model lets server operators control commands from several Vyvern mods through one set of nodes.
In-game hub GUI
A translucent tab rail gives players a single screen where panels from other Vyvern mods appear.
Bus command dispatch
Commands from other mods can be dispatched over the WebSocket bus, so they can be triggered from a connected panel.
Optional remote panel
A WebSocket bus connects the hub to a Vyvern panel for remote management, and stays inactive until configured.

Use cases
Running several Vyvern mods on one server
Server owners who install Vyvern Mine, Vyvern Teams or Vyvern Stats can manage their permissions from a single model.
Who it’s for: Server operators who run more than one Vyvern companion mod and want shared permissions and one hub screen. Players on a server with these mods see the same hub, since the mod is needed on the client as well.
