[v3] Strongly typed custom events are not being generated in the bindings
Description
I’m running into an issue with strongly typed custom events in Wails3 and wanted to check whether this is expected behavior, a documentation mismatch, or a bug in the generator.
My test environment: wails3 -n aNameForThisTestProject -t react
This is a freshly generated standard template project, with no custom generation setup beyond the template defaults
To Reproduce
wails3 init -n aNameForThisTestProject -t vanillaorwails3 init -n aNameForThisTestProject -t react- enter the project, and add some custom events (using examples from wails3 doc here):
func init() {
application.RegisterEvent[string]("time")
application.RegisterEvent[UserLoginData]("user:login")
application.RegisterEvent[MonitorStats]("monitor:stats")
application.RegisterEvent[application.Void]("app:ready")
}wails3 dev
Expected behaviour
According to the Wails v3 documentation for custom events: https://v3.wails.io/guides/events-reference/#registering-custom-events I expected Wails to generate a frontend bindings/events folder or equivalent typed event files for the registered events, so typed events can be easily import like this:
import { UserLogin, MonitorStats } from './bindings/events'But there is no events folder was generated under the frontend bindings. I can only find events definations in frontend/bindings/github.com/wailsapp/wails/v3/internal/eventdata.d.ts.
In this template, the wails vite plugin will handle these events automantically. But in non-vite project, i have to reference it manually to provide events definations to ts language server. Is the current generation behavior as expected?

I have already tried templates vanilla and react
I’d really appreciate any guidance on whether I’m using the feature incorrectly, or whether this is a mismatch between docs and the current generator output.
