[improve vite:cssPlugin] add a cache for this plugin?

Clear and concise description of the problem

packages/vite/src/node/plugins/css.ts

buildStart() {
      ...
      moduleCache = new Map<string, Record<string, string>>()
      ...
},

In this line, I want to be able to use local cache. Because every restart will compile once.

In my case , server side use createServer create vite instance, use vite.middlewares to render.

But when server side modify code, will restart server and createServer again, too many less files using too much time, pending(TTFB) every time when vite server restart.

js files won’t.

Suggested solution

maybe like

const needCache = optiosn.xx
moduleCache = needCache ? cache : new Map<string, Record<string, string>>()

For SSR, Vite has an API for it, which might help if the framework’s setup. I’m not familiar with the framework enough to tell how to integrate it though, but I’d try to avoid restarting the Vite server as much as possible as you’ve mentioned. I’ll close this as a wontfix, but feel free to keep the discussion going, or as a GitHub discussion if you have any questions!

Thanks.

I have found JS files have a version ?v=xxx, css/less files wouldn’t. All because of this.
