decoval/lib/dv/register.validation.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.

const validationMetadata = new Map();
function getValidationKey(target, key) {
    const constructor = typeof target === "function" ? target.name : target.constructor.name;
    return `${constructor}.${key}`;
}
export function registerValidation(target, key, validator) {
    const propertyKey = getValidationKey(target, key);
    if (!validationMetadata.has(propertyKey)) {
        validationMetadata.set(propertyKey, []);
    }
    const validators = validationMetadata.get(propertyKey);
    if (!validators.includes(validator)) {
        validators.push(validator);
    }
}
export { validationMetadata };
