fix(react): Export named deriveFromSsrInitialState not found

Description

Fix SyntaxError: Export named 'deriveFromSsrInitialState' not found in module '/var/task/node_modules/@clerk/shared/dist/runtime/deriveState.mjs'.

}

Behavior is unchanged; only the way the shared package is used is simplified and no longer relies on the internal named exports that were missing in your runtime.

Cause:

The error happens when the app (e.g. on Vercel) loads @clerk/shared/dist/runtime/deriveState.mjs. That file re-exports from an internal chunk (e.g. deriveState-xxxxxx.mjs). In some environments or with different build/publish setups, the named exports deriveFromSsrInitialState and deriveFromClientSideState can end up missing from the resolved module, which triggers the “Export named 'deriveFromSsrInitialState' not found” error.

Fix:

useAuthBase was updated to use only the public deriveState API from @clerk/shared/deriveState instead of the internal helpers, so the hook no longer depends on those named exports.

📝 Walkthrough

Walkthrough

This change consolidates two derive utilities into a single deriveState API within useAuthBase.tsx. The initial-state and non-initial code paths now call deriveState with different argument configurations instead of using deriveFromClientSideState and deriveFromSsrInitialState. Imports were updated to bring in deriveState and the DeriveStateReturnType type from @clerk/shared/deriveState. No public API signatures were modified. Lines changed: +4/-3.

🚥 Pre-merge checks | ✅ 1 | ❌ 2

❌ Failed checks (2 warnings)

Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The title references a specific error ('Export named deriveFromSsrInitialState not found') but the actual fix removes the use of these exports entirely, replacing them with deriveState API calls. The title describes the symptom/error but is misleading about the actual solution implemented.	Update the title to reflect the actual change: something like 'fix(react): Replace internal deriveState helpers with public deriveState API in useAuthBase' would accurately describe what was changed.
Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
