Fixes voidzero-dev#525 ## Summary Adds `setError(field, message)` to `useForm` across React, Vue, Svelte, and Solid so apps can surface client-side validation through the same typed `errors` object as server `withValidator()` responses. Changing a field clears that field's validation error automatically: - React and Solid: `setData(field, value)` clears `errors[field]` - Vue and Svelte: assigning to `data` clears `errors[field]` (snapshot-based watch / $effect) ## API | Method | Purpose | | --- | --- | | `setError(field, message)` | Set a client-side field validation error | | (existing) `clearErrors(...fields)` | Clear validation errors manually | ## Tests - `packages/vue/test/unit/use-form.test.ts` — `setError` and clearing on `data` change ## Docs - `docs/guide/pages-routing/actions-and-forms.md` - `docs/reference/api/pages.md` ## Typecheck `@void/react`, `@void/vue`, `@void/svelte`, `@void/solid` ## Fit to voidzero-dev#525 Implements proposal (1) `setError(field, message)` and proposal (2) clear-on-change via `setData` / `data` assignment, unblocking client-side schema validation in userland without a second error state.
