Field()

Creates a field to chain with your rules to build complex validation for your data.

Example

import { Field } from "v4f";

const username = Field()
    .string()
    .min(6) // min length 6
    .max(10) // max length is 10
    .last("z") // last char must be "z"
    .required(); // must be no empty and no null or undefined

username.validate("nassihfz"); // true

username.validate(""); // false

username.validate("abc1z"); // false
