Vite and Rollup output structure

Question

I have an app on create-react-app that builds with its structure like in a screen webpack-build. How can I manage the same structure in Vite? I got only the 'build' output folder, but cannot manage the inner structure in there.

Here is my Vite-Rollup output config:

build: {
    emptyOutDir: true,
        rollupOptions: {
        output: {
            dir: 'build',
        },
    },
},

And here is what I've got on build success: Vite-build

I already tried playing with the output.entryFileNames function, didn't help. Here is what I've got

entryFileNames: (chunk) => {
    const extension = chunk.facadeModuleId.slice(
        chunk.facadeModuleId.indexOf('.') + 1,
    )

    return `${extension}/[hash].${extension}`
},
