Schema - NotOneOf
The .notOneOf method is used to validate whether a given value does not match any of several specified values or schemas. It ensures that the input value must not match any of the provided values or schemas in the array. This method is essential when you need to validate data that must exclude certain possibilities, such as rejecting specific predefined values or structures.
Example: Basic Validation with .notOneOf
Below is an example of how to use .notOneOf to validate whether a value does not match any of the comparison values or schemas:
import { schema } from "vkrun"
// Comparison items can include static values and schemas
const comparisonItems = ["hello", "world", schema().boolean()]
const exampleSchema = schema().notOneOf(comparisonItems)
// Validate against the schema
const validateA = exampleSchema.validate("hi") // No match
const validateB = exampleSchema.validate(42) // No match
const validateC = exampleSchema.validate("hello") // Match (invalid)
const validateD = exampleSchema.validate(true) // Match (invalid)
console.log(validateA) // true
console.log(validateB) // true
console.log(validateC) // false
console.log(validateD) // false
