Purpose

Fixes two bugs in the @thunderid/react SDK:

  • Validation error messages were frozen in the language active at validation time. Switching the UI language updated all other strings but left displayed errors untranslated.

  • Invalid email input showed the raw i18n key field.email.invalid instead of a translated error message, across all three identity deployments.

Approach

1. — Error re-translation on language switch

The root cause: useForm stores errors as resolved translated strings in state. When the language changes, new validators are built correctly but nothing re-runs them on already-displayed errors.

Fix:

  • Added revalidateTouchedFields() to useForm — a stable callback (empty deps) that uses "latest value" refs to re-run validation on all touched, client-validated fields inside a functional setFormErrors updater. Fields whose errors originated from the server (no matching FormField config) are skipped to prevent server messages from being silently wiped.
  • In BaseSignIn, added a useEffect([currentLanguage, revalidateTouchedFields]) to call it on every language change.

2. — Raw i18n key rendered as email error

  • The SDK had a hardcoded email regex check that returned t('field.email.invalid') — a key that never existed in any translation bundle. This check fired before the declarative ruleValidator (which correctly uses the translated validation.email.format key from the flow YAML), short-circuiting it entirely.
  • Removed the redundant hardcoded email validation from BaseSignIn, BaseSignUp, and BaseRecovery. Email validation now flows exclusively through the declarative rule system with properly translated messages.

@SajidMannikeri17, you've reached your PR review limit, so we couldn't start this review.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 Walkthrough

Walkthrough

The authentication forms remove hard-coded email-format checks. Declarative validation remains active. useForm adds touched-field revalidation, and sign-in invokes it when the UI language changes.

Changes

Authentication form validation

Layer / File(s) Summary
Touched-field revalidation API
packages/react/src/hooks/useForm.ts
useForm exposes revalidateTouchedFields, which revalidates touched fields, updates client-side errors, and preserves server errors.
Authentication form validation integration
packages/react/src/components/presentation/auth/Recovery/BaseRecovery.tsx, packages/react/src/components/presentation/auth/SignIn/BaseSignIn.tsx, packages/react/src/components/presentation/auth/SignUp/BaseSignUp.tsx
The forms remove hard-coded email-format checks. Sign-in revalidates touched fields when the current language changes.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Mergeability Score: 🟡 Moderate · up to 20367

The PR improves translated validation messages and removes an invalid email key, but its current error tracking can still clear or overwrite form-level or server-provided errors during language changes. This can show users the wrong validation state, so the ownership and revalidation handling should be fixed before merging.

427-443: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Drop client-error tracking when setError / setErrors inject server errors.

clientErrorFieldRef is not updated in setError or setErrors. If a field was client-invalid earlier, it stays in the set after a server error is applied.

On the next revalidateTouchedFields call, that field is treated as client-owned. A passing client check deletes the server message. A failing client check overwrites it.

Remove each updated field from clientErrorFieldRef when setting external errors. Add a regression test: touched field with a prior client error, then setError, then revalidate must keep the server message.

🐛 Proposed fix
   const setError: (name: keyof T, error: string) => void = useCallback((name: keyof T, error: string): void => {
+    clientErrorFieldRef.current.delete(name);
     setFormErrors((prev: Record<keyof T, string>) => ({
       ...prev,
       [name]: error,
     }));
   }, []);

   const setErrors: (newErrors: Partial<Record<keyof T, string>>) => void = useCallback(
     (newErrors: Partial<Record<keyof T, string>>): void => {
+      (Object.keys(newErrors) as Array<keyof T>).forEach((name) => {
+        clientErrorFieldRef.current.delete(name);
+      });
       setFormErrors((prev: Record<keyof T, string>) => ({
         ...prev,
         ...newErrors,
       }));
     },
     [],
   );

Align the revalidateTouchedFields docs with the implementation.

The JSDoc describes revalidation of touched fields that have client-side config. The implementation revalidates fields whose current error is tracked in clientErrorFieldRef, and it does not read touched.

Update the comment so callers know the contract is client-error provenance, not touched state or field config.

📝 Proposed doc fix
   /**
-   * Re-run validation for all touched fields that have a client-side config,
-   * refreshing stored error strings to the current language.
+   * Re-run client-side validation for fields whose current error was produced
+   * by client validation, refreshing stored error strings (e.g. after a language
+   * change). Errors set via `setError` / `setErrors` are left unchanged.
