decoval/lib/dv/dv-url.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 "./error/validation.error";
import { registerValidation } from "./register.validation";
import { skipValidation } from "./skip/skip.validation";
export function DvURL(options) {
    return function (target, propertyKey) {
        const customMessage = (options === null || options === void 0 ? void 0 : options.message) || `The "${propertyKey}" field must be a valid URL`;
        const urlRegex = /^(https?:\/\/)?([\w\d\-]+\.)+[a-z]{2,6}(:\d+)?(\/[\w\d\-._~:/?#[\]@!$&'()*+,;%=]*)?$/i;
        registerValidation(target, propertyKey, (value) => {
            var _a;
            const skipOpts = {
                optional: true,
                null: (_a = options === null || options === void 0 ? void 0 : options.allowNull) !== null && _a !== void 0 ? _a : true,
                empty: true,
            };
            if (skipValidation(value, skipOpts))
                return;
            if (typeof value !== "string") {
                throw new ValidationError(customMessage);
            }
            if (!urlRegex.test(value)) {
                throw new ValidationError(customMessage);
            }
        });
    };
