Add Typescript to handle global types?

[RobertGemmaJr]

We definitely want to steer away from .ts files but I wonder if adding typescript to the project will be useful simply for the typing of global variables?

• typing of Vite global variables (MAIN_WINDOW_VITE_DEV_SERVER_URL, MAIN_WINDOW_VITE_NAME)
• Typing of import.meta.env (properties from Vite)
• Typing of import.meta.env (Custom environment variables)

I don't think I need typescript? Just add an index.d.ts file
