Describe the bug

Vite server as middleware unable to serve index.html on GET /

Reproduction

In server.ts:

const app = express();
const server = http.createServer(app);
const vite = await createServer({ server: { middlewareMode: true } });
app.use(vite.middlewares);
server.listen(3000);

Visiting localhost:3000 in the browser results in a 404 (Cannot GET /), even though there is a index.html file in the same directory as the server

Thanks @yyx990803, I was able to get it working. One limitation that I would note with this approach is that HMR doesn’t work properly on index.html – I see a {type: "full-reload", path: "/index.html"} websocket message but it’s not accompanied by a full page refresh.
