- This is a precursor to trying to split apart into:
- model events + webhooks system which makes sense
- frontend events which should be independent or removed
- maybe some concept of a settings manager that we can use in various places to bind logic 🤔
- other usages of events that should be refactored to not use events

/**
|
|
* The Bridge
|
|
*
|
|
* The bridge is responsible for handing communication from the server to the frontend.
|
|
* Data should only be flowing server -> frontend.
|
|
* As the architecture improves, the number of cross requires here should go down
|
|
* Eventually, the aim is to make this a component that is initialised on boot and is either handed to or actively creates the frontend, if the frontend is desired.
|
|
*
|
|
* This file is a great place for all the cross-component event handling in lieu of refactoring
