Schema - ValidateAsync
The .validateAsync method is used to validate data asynchronously against a predefined schema. It takes a value (or a Promise resolving to a value) as input, checks if the value satisfies the schema's validation rules, and returns a Promise resolving to a boolean indicating whether the value is valid.
Syntax
.validateAsync(value: any): Promise<boolean>- value: The value to be validated.
Example
The following example demonstrates how to use .validateAsync to check if a value is a valid email:
import { schema } from "vkrun"
const schemaNumber = schema().number()
const valueA = async (): Promise<number> => {
return await new Promise((resolve) => {
setTimeout(() => {
resolve(123)
}, 100)
})
}
const valueB = async (): Promise<string> => {
return await new Promise((resolve) => {
setTimeout(() => {
resolve("123")
}, 100)
})
}
const validateAsyncA = schemaNumber.validate(valueA())
const validateAsyncB = schemaNumber.validate(valueB())
console.log(validateAsyncA) // true
console.log(validateAsyncB) // false
