It affects the operation of vite when in dev mode.

Is it similar to affecting Vite's workflow?

In this project, @samrum/vite-plugin-web-extension was added.
It would normally open a websocket connection to localhost:5173.
After adding vue-router, it attempts to redirect to localhost:5173// instead of the expected //.
It appears to be covering the functionality of @samrum/vite-plugin-web-extension.

You probably need to use the createMemoryHistory() but you should ask in the other repo instead
