fix: share the loading flag in every renderer and make boundaries nest (BON-11, BON-14) - #44

Conversation
…t (BON-11, BON-14) The flag BonesStart/BonesEnd bracket around a skeleton tree lived in React.cache(), which memoizes per request only inside React Server Components. Client renders and non-RSC server rendering got a fresh object per read, so BonesForce and the <Bones> fallback never forced anything there. getBonesContext now calls the cached getter twice: identical objects mean a request-scoped context, different objects mean the passthrough, where a shared module context takes over. The brackets also track a depth instead of a boolean, so a nested boundary's end restores the outer level instead of clearing the flag for the outer boundary's later siblings. A counter stays balanced under StrictMode's double render, where a saved-previous-value slot would capture its own true and leak. Co-Authored-By: Claude Fable 5 <[email protected]>

- Around line 39-44: Update getBonesContext and the non-RSC context flow to use
render-local state instead of the module-level moduleContext, so an abandoned
render cannot leave depth or loading state visible to an error-boundary fallback
or later root. Preserve the request-local getRequestContext behavior for RSC and
retain the existing BonesContext API.

A child that throws between BonesStart and BonesEnd unwinds past BonesEnd, leaving the module context's depth raised for every render after the error boundary. BonesForce and the Bones fallback now wrap their children in a relay boundary that restores the pre-bracket depth and rethrows for the app's own boundary. Module-context path only: the request context dies with its request, and class components cannot render in Server Components. Addresses the CodeRabbit review on PR #44. Co-Authored-By: Claude Fable 5 <[email protected]>
Next's compiler rejects a Component import in any module server components evaluate, build-time, regardless of the runtime path check. The relay now lives in its own "use client" module, which the RSC bundler turns into an unused client reference on the server path; vp pack preserves the directive in dist/react/recover.mjs. Also passes children inside the props object, fixing the createElement overload error the CI lint caught. Co-Authored-By: Claude Fable 5 <[email protected]>

Fixes BON-11 and BON-14 together — investigation showed they're one mechanism.
The flag
BonesStart/BonesEndbracket around a skeleton tree lived inReact.cache(). Probing every environment showedcache()memoizes per request only inside a real RSC render: in client renders (react-dom/client), non-RSC SSR (renderToString), and plain calls, every read returns a fresh object. SoBonesForceand the<Bones>fallback never forced anything outside RSC (BON-14 — and wider than filed, since SSR is affected too), and inside RSC a nested boundary'sBonesEndcleared the flag for the outer boundary's later siblings (BON-11).Two changes to the mechanism:
getBonesContextcalls the cached getter twice. Identical objects mean a request-scoped context (concurrent-request safe, the RSC path, unchanged). Different objects mean the passthrough, where a shared module context takes over — safe because those render passes are synchronous with balanced brackets.Startincrements,Enddecrements,loadingisdepth > 0. A nested boundary's end restores the outer level instead of clobbering it. A counter was chosen over the issue's save/restore suggestion deliberately: StrictMode double-invokes render functions, and++ ++ -- --stays balanced where a saved-previous-value slot would capture its owntrueand leak the flag past the boundary.getBonesContextis internal (not exported from the react entry), so no public API changes — patch changeset.Five new tests pin the behavior: client-render forcing,
renderToStringforcing, the nested-BonesForcelater-sibling repro from BON-11, flag cleanup after a boundary, and the nested-<Bones>-fallback variant where a later sibling's bones depend entirely on the bracketed flag. All five were verified failing againstmain's source before the fix (matcher-free assertions, per the suite's convention). Full suite: 195/195.Fixes BON-11, BON-14.
