@mub22/validity/dist/validateForm.js

Lightweight JavaScript validation library inspired by Laravel's rule syntax. Validate fields and forms easily with built-in rules and error messages.

import { validate } from "./validate";
import { rulesWithData } from "./rulesWithData";
export function validateForm(data, rules) {
    let isFormValid = true;
    const errors = {};
    for (const field in rules) {
        const value = data[field];
        /* Validations */
        /* Skip internal fields */
        if (/^__/.test(field))
            continue;
        const ruleList = rules[field].split("|");
        if (!ruleList.length)
            continue;
        let result;
        if (ruleList.some(rule => rule in rulesWithData)) {
            data.__field__ = field;
            result = validate(value, rules[field], data);
        }
        else {
            result = validate(value, rules[field]);
        }
        if (!result.valid) {
            errors[field] = result.errors;
            isFormValid = false;
        }
    }
    return {
        valid: isFormValid,
        errors
    };
}
