I have no idea to process this situation. so if anybody dealt with this situation. give me some response please~

@cawa-93 sorry to disturb you~

There is no way. vite.config.js is a configuration that is read and processed exclusively in compile time and does not exist in run time. At the same time, ipcRenderer is a module that provides communication between the main and the renderer in the run time.

I see two ways depending on your task:

• Make what you want to share in a separate file and just import it into Main and renderer.
• Transfer what you want to share to the renderer src and send from there using IPC

in my case. i wanna fetch cached data from some local-db from main process when the rollup load hooks is invoked. and then. I can change Vue sfc content dynamic.
as you mention above. Is any other way to do this beside IPC communication?

I even thought about using http request to get info...
but it is too slow..

If you want use "rollup load hooks" then you should create plugin for vite. It fetch your data and modifi vue sfc, or pass it to define

Try to create function-wrapper in preload like this. And use it like window.wrapperFunc(...)
