formik-validation-adaptors/dist/vestValidator.js

A lightweight utility to integrate Zod and Joi validation with Formik.

var __awaiter = (this && this.__awaiter) || function (thisArg, _arguments, P, generator) {
    function adopt(value) { return value instanceof P ? value : new P(function (resolve) { resolve(value); }); }
    return new (P || (P = Promise))(function (resolve, reject) {
        function fulfilled(value) { try { step(generator.next(value)); } catch (e) { reject(e); } }
        function rejected(value) { try { step(generator["throw"](value)); } catch (e) { reject(e); } }
        function step(result) { result.done ? resolve(result.value) : adopt(result.value).then(fulfilled, rejected); }
        step((generator = generator.apply(thisArg, _arguments || [])).next());
    });
};
/**
 * A Formik-compatible validation function using Vest.
 *
 * @param {Suite<string, string, (data: any) => void>} suite - The Vest test suite used for validation.
 * @returns A validation function for Formik, returning validation errors as an object.
 *
 * @example
 * ```ts
 * import vest, { test, create } from "vest";
 * import formikVestValidator from "./formikVestValidator";
 *
 * // Define a Vest validation suite
 * const suite = create((data) => {
 *   test("name", "Name is required", () => {
 *     enforce(data.name).isNotEmpty();
 *   });
 *
 *   test("email", "Invalid email format", () => {
 *     enforce(data.email).matches(/^[\w-.]+@([\w-]+\.)+[\w-]{2,4}$/);
 *   });
 * });
 *
 * // Use in Formik
 * const formik = useFormik({
 *   initialValues: { name: "", email: "" },
 *   validate: formikVestValidator(suite),
 *   onSubmit: (values) => console.log(values),
 * });
 * ```
