Less dynamic pages manifest path by mischnic · Pull Request #90581 · vercel/next.js

mischnic · 2026-02-26T11:04:34Z

Two steps forward, one step back

I ended up having to keep the build id in _next/data routes anyway (and made the id a constant if skew protection is enabled). This was because it was utterly impossible to change the routes from _next/data/:buildId/* to _next/data/* in the builder in a backwards-compatible way.

So there is no need to remove the build id from _next/static here either. It just makes testing a huge pain because the paths keep changing

Additional Suggestion:

The deploymentId: string property remains as a required field in TurbopackManifestLoader's constructor type parameter despite being completely unused after the PR's cleanup, forcing callers to pass a value that is silently ignored.
