Schema - Boolean

The .boolean method is used to validate whether a given value is of type boolean. It ensures that the input is either true or false, making it useful for validating data like toggle states, flags, or any binary value.

This method is essential for enforcing strict type validation where only Boolean values are acceptable.

Example

Below is an example of how to use .boolean to validate whether a value is a valid Boolean:

import { schema } from "vkrun"
 
const exampleSchema = schema().boolean()
 
const validateA = exampleSchema.validate(false)   // Valid Boolean
const validateB = exampleSchema.validate("false") // Invalid, string is not a Boolean
 
console.log(validateA) // true
console.log(validateB) // false
