Proposal: Add getErrors Method to React Hook Form

[kcsujeet]

Overview:

I’d like to propose a new method for React Hook Form: getErrors. This method would function similarly to getValues, but instead of retrieving form values, it would return the current form errors for a given field or all fields.

Why It’s Useful:

• No re-renders: Unlike useFormState, which subscribes to form state and can trigger re-renders, getErrors would provide a snapshot of the current errors on demand—ideal for non-reactive use cases.
• On-demand access: Perfect for accessing validation errors during function calls like onSubmit, custom validations, or conditional logic outside of the render cycle.
• Developer ergonomics: Cleaner and more intuitive than subscribing to error state when only occasional access is needed.

Example usage:

const errors = getErrors();
const emailError = getErrors("email");

This would make form handling more flexible, especially in performance-sensitive scenarios where avoiding unnecessary renders is important.
