email

The string looks like an email: something@something.something, no spaces.

Signature

function email(msg?: Message): Action<string>

Parameters

Parameter	Type	Description
msg	Message	Custom error message. A string with {params} or a function

Error codes

Code	When	Default message
email	Does not look like an email	Invalid email

You can change the texts: see Messages & i18n.

Notes

• The check is intentionally simple: strict email regexes often reject real addresses. The only way to know an address exists is to send an email.
• Usually combined with trim and toLowerCase to store emails consistently.

Example

Email

pipe(string(), trim(), toLowerCase(), email())
