[Nuxt Integration] Return dynamicDeps in transformRequest

[antfu]

Clear and concise description of the problem

In Nuxt, we are trying to use Vite Server for generating the SSR bundle on-demand instead of build with watcher - to align with the client behavior and get the perfance juice. We use a custom script with server.transformRequest to construct the bundle, currently we are facing an problem that dynamic depdenencies are not included in the deps array of the transform result.

Suggested solution

Return dynamicDeps list for transformRequest

const {
  code,
  deps,
  dynamicDeps,
} = await server.transformRequest('id')

Alternative

No response

Additional context

Current workaround:

function scanDynamicDeps (code: string) {
  return Array.from(code.matchAll(/__vite_ssr_dynamic_import__\(['"](.+?)['"]\)/g)).map(m => m[1])
}

const res = await transformRequest(viteServer, id)
// Vite does not include dynamic deps in `res.deps`, we manually scan for it
const dynamicDeps = scanDynamicDeps(res.code)
const deps = uniq([...res.deps, ...dynamicDeps])
