[Vite] The Vite server doesn't restart on vite.config.js change

[vursen]

Description of the bug

In a basic Vite example, you can see that Vite automatically restarts the server once you change the Vite config file that is vite.config.ts by default.

However, for some reason, nothing seems to restart when changing vite.config.ts in a Flow / Fusion project.

Minimal reproducible example

The problem can be seen in any Flow / Fusion project created with https://start.vaadin.com/welcome.

Expected behavior

The Vite server automatically restarts when vite.config.ts changes.

Actual behavior

The Vite server doesn't restart when vite.config.ts changes.

My workaround for restarting vite on file change:

1. create vite.js

import { createServer } from "vite";
import config from "./vite.config.js";

(async () => {
  const server = await createServer({
    // any valid user config options, plus `mode` and `configFile`
    ...config,
    configFile: false,
  });
  await server.listen();

  server.printUrls();
})();

2. start using nodemon

npx nodemon vite.js
