figure out ssr.optimizeDeps for vite-node-miniflare

[hi-ogawa]

Initially, I gave up vite-node's prebundling for vite-node-miniflare + react demo, then later ended up with creating my own pre-bundling plugin:

• chore(vite-node-miniflare): add react demo #125
• feat(vite-node-miniflare): add vitePluginPreBundle #128

but maybe optimizeDeps was never made to work in vite-node ssr as explained in this issue:

• Dependency optimization does not work in SSR transform mode vitest-dev/vitest#4910

Quick workaround could be to trigger dummy ssrLoadModule in configureServer hook?

https://stackblitz.com/edit/vitest-dev-vitest-8wf26p?file=vite.config.ts

import { defineConfig } from 'vite';

export default defineConfig({
  plugins: [
    {
      name: 'force-ssr-optimize-deps',
      configureServer(server) {
        return async () => {
          console.log('[trigger ssrLoadModule]');
          const mod = await server.ssrLoadModule('/dummy-module.js');
          console.log('[dummy-module]', mod);
        };
      },
    },
  ],
});
