• parseAstAsync
  • for now, use it from rollup/parseAst
• virtual:copy-server-css.js
  • two rsc builds chunking difference? (the approach is unsound in rollup vite already)
  • the issue is that 2nd rsc build's manifest includes css output which is only available in 1st rsc build.
    • not only css, but also __client-CCH4vHkY.js chunk is included in manifest.
    • it looks like only manifest issue and two builds are mostly working fine.
  • does the same issue happen in standard rolldown-vite watch build?
  • actually it looks like the behavior (stale manifest) is same with rollup/vite, but the difference is that rolldown now generates _client.js (and thus _client.css) in 1st rsc build, which wasn't the case. Maybe I was relying on no side effect elision, which is not working on rolldown?
    but the difference is that previously there are less chunks in rollup and thus manifest entry is overwritten without stale content showing up after 2nd rsc build
  • this will get fixed by fix(build): fix stale build manifest on watch rebuild vitejs/vite#19361
    though we might need to revisit double environment build to avoid this type of issue

examples/web-worker

• worker-in-worker build relies on import.meta.ROLLUP_FILE_URL_xxx
  • should be fixed by feat: support import.meta.ROLLUP_FILE_URL_(referenceId) rolldown/rolldown#3488
  • no it doesn't 😢 rolldown needs to support rollup file url for emitFile({ type: "chunk" }
