decoval/lib/helpers/date.js

DecoVal is a decorator-driven validation pattern that allows you to add validation rules directly to the properties of TypeScript classes, simplifying data control and increasing code readability and reusability.

import { ValidationError } from "../dv/error/validation.error";
import { registerValidation } from "../dv/register.validation";
export function IsDate(message) {
    return (target, key) => {
        registerValidation(target, key, (value) => {
            if (!(value instanceof Date) || isNaN(value.getTime())) {
                throw new ValidationError(message || `Property "${key}" must be a valid date.`);
            }
        });
    };
}
