strictTuple

Creates a strict tuple schema.

const Schema = v.strictTuple<TItems, TMessage>(items, message);

Generics

• TItems extends TupleItems
• TMessage extends ErrorMessage<StrictTupleIssue> | undefined

Parameters

• items TItems
• message TMessage

Explanation

With strictTuple you can validate the data type of the input and whether the content matches items. If the input is not an array or does include unknown items, you can use message to customize the error message.

The difference to tuple is that this schema returns an issue for unknown items.

Returns

• Schema StrictTupleSchema<TItems, TMessage>

Examples

The following examples show how strictTuple can be used. Please see the arrays guide for more examples and explanations.
