Signature

function setMessages(messages: Record<string, Message>): void

Parameter	Type	Description
`messages`	`Record<string, Message>`	An error code (`required`) or a field and code (`email.required`, `items.*.title.required`) → text or a function `(params) => string`. Other messages stay unchanged

It is global — call it once on startup. For the language of a single request use the messages option of validate.
A message passed to a rule (minLength(3, '...')) takes precedence over the global one.
A full custom lang file: npx tinyval lang ru — see Custom lang file.
You can add messages for your own error codes — see Custom rules & schemas.
The list of codes is in Messages & i18n.
