Turbopack Build: Optimize instrumentation hook generation #77832

timneutkens · 2025-04-04T14:09:16Z

Add compiled in for middleware and instrumentation in Turbopack dev.
Fixed a bug where instrumentation.js was being compiled like a page file, local testing moves bootup from 2.5s to 700ms when you have a instrumentation file.

Added early returns in hot-reloader-turbopack.ts for middleware and instrumentation paths when there's no route definition, those cases are handled separately already.
Added build status indicators in turbopack-utils.ts for middleware and instrumentation using startBuilding and finishBuilding hooks
Added proper naming for Node.js and Edge instrumentation in the build status
