emailFieldToInputSchema

emailFieldToInputSchema(props): ZodType

Defined in: packages/core/src/fields/email/inputSchema.ts:39

Builds a Zod schema for validating an email field value in the admin form and the server write pipeline.

The email-format check (.email()) is chained onto the same z.string() call as min/max — not .pipe()d after them — so every configured check runs and reports together, matching textFieldToInputSchema’s CORE-1 composition rule. A required field’s emptiness is checked first (.min(1, requiredError)) so a missing value reports “This field is required.” rather than the format error.

A non-required field’s empty string bypasses the format check entirely — z.union([emailSchema, z.literal("")]), the same escape hatch urlFieldToInputSchema uses — because an untouched admin-form input holds "", not undefined, so .default() alone (which only fires on undefined) can never save an empty optional email from failing .email().

min/max read field.min/field.max directly as [value, error] — resolveFieldLimit (step 1) already guarantees error is set whenever the tuple is present, so no further fallback is needed here.

Parameters

props

Input props.

field

EmailField

The resolved email field definition.

Returns

ZodType

A Zod schema enforcing required/length/email-format constraints and optionality.

Example

const field = email({ required: true, min: [5, "Too short."] })
emailFieldToInputSchema({ field })
// → required, min-length 5, format-checked string
