DevTools still reported "Profiling not supported" because the build was never a profiling one, despite three settings appearing to enable it. Next applies the React swap through a webpack alias — getReactProfilingInProduction, mapping 'react-dom/client$' to 'react-dom/profiling' — that Turbopack never sees. A Turbopack resolveAlias does not catch it either: the vendored entry requires ./cjs/react-dom-client.production.js relatively, not through a bare specifier. The Dockerfile now performs that same swap on the vendored entry when HOMARR_PROFILING=true, guarded so it fails the build loudly if React's file layout changes rather than silently producing a normal build again. Added `pnpm docker:profiling`, which builds and then verifies, because `docker build . -t homarr:performance` alone yields a non-profiling image and that is almost certainly what was being run. verify-react-profiling.mts checks the bundle rather than the runtime: 2 client chunks carry React's profiling renderer with the flag, 0 without. It replaces a Playwright probe that could not tell the two apart — React sends a reduced inject payload to a synthetic devtools hook, byte-identical for both builds, so that probe reported a false negative for profiling and production alike. The bundle marker discriminates; confirm the Profiler tab itself with the real extension.
Create T3 App
This is a T3 Stack project bootstrapped with create-t3-app.
What's next? How do I make an app with this?
We try to keep this project as simple as possible, so you can start with just the scaffolding we set up for you, and add additional things later when they become necessary.
If you are not familiar with the different technologies used in this project, please refer to the respective docs. If you still are in the wind, please join our Discord and ask for help.
