textareaFieldToInputSchema

textareaFieldToInputSchema(props): ZodType

Defined in: packages/core/src/fields/textarea/inputSchema.ts:33

Builds a Zod schema for validating a textarea field value in the admin form.

Applies min/max character-length constraints by composing them onto the same schema chain built for required, rather than reassigning over it — a required field with min/max configured keeps every check (CORE-1, mirrored from text). Required fields attach { error: "This field is required." } to the base z.string() call and add .min(1, "This field is required.") so a missing value and an explicit empty string report the same message; they never receive .default(), matching applyBaseInputSchemaMeta’s .optional() gate. Non-required fields keep .default(field.defaultValue). field.min/ field.max are already-resolved FieldLimit tuples ([value, error]) — resolveFieldLimit (step 1) guarantees an error message, so neither branch needs a fallback.

Parameters

props

Input props.

field

TextareaField

The resolved textarea field definition

Returns

ZodType

A Zod string schema with length constraints and optionality applied

Example

const field = textarea({ required: true, min: 3, max: 100 })
textareaFieldToInputSchema({ field })
// → z.string({ error: "This field is required." }).min(1, "...").min(3).max(100)
