Only problem is that vim doesn't work with LSP. It is a broken tool.

Easy check proving absolutely that it is broken:

1. Create a new wails project with `wails init -n myproject -t svelte-ts` 2. Create a svelte file and use a function defined in app.go 3. Run `wails dev` to compile and run the app 4. Delete the function from app.go

Result: The svelte file which imports the function generated from app.go doesn't show any errors even thought the function doesn't exist anymore.

So use VS Code or Sublime which actually work with LSP without issues.

Don't use broken tools for your work.
