Write to disk option for Vite

Question

recently I have started working with vite on a couple of small projects and found it very interesting, however got a blocker once tried to work on ExpressJS + Svelte coupled project.

I usually use Express as BFF (Backend For Frontend) when it comes to working on rather more serious projects since it allows me to go for HTTPOnly cookies as well as proxy gateway for the frontend. However for development (specially when it comes to oauth2) it is hard to develop the spa separated form the server so what I usually do with webpack is activating the WriteToDisk option for devserver which then allows me to have my development build in the dist folder.

Example with webpack will be something like the webpack config below for the frontend:

    module.exports = {
        devServer: {
            devMiddleware: {
                writeToDisk: true,
            },
        },
        //...
    }

and then on the server basically rendering the dist as static folder:

    app.get(
      "*",
      (req, res, next) => {
        if (req.session.isAuth) return next();
        else return res.redirect(staticURL);
      },
      (req, res) => {
        return res.sendFile(staticProxyPage());
      }
    );

My problem

I can not find in vite's documentation any APIs to do something like this, does anyone have any experience with such cases?

if it is possible with the help of plugins, can you please provide references to the plugin or dev logs of it?

Many Thanks :)
