Release Date: December 4, 2025

We're thrilled to announce @formajs/mold v2.0.0 – a major update that brings powerful new formatting capabilities, enhanced locale management, and improved compatibility with the latest FormaJS v2.0.0. This release transforms Mold from a pure validation library into a comprehensive data transformation and validation powerhouse.

🚀 What's New

✨ New Formatting Capabilities

Mold now supports formatters alongside validators and sanitizers, enabling complete data transformation pipelines:

String Schema Formatters

const userSchema = forma.object({
  birthDate: forma.string().formatDate({ locale: 'pt-BR' }),
  phone: forma.string().formatMobileNumber({ style: 'international' }),
  postalCode: forma.string().formatPostalCode(),
  taxId: forma.string().formatTaxId(),
  salary: forma.string().formatCurrency({ currency: 'BRL' }),
});

Number Schema Formatters

const statsSchema = forma.object({
  percentage: forma.number().toPercentage({ decimals: 2 }),
  accessibleNumber: forma.number().toAccessible(),
  price: forma.number().formatCurrency({ currency: 'USD' }),
});

🌍 Enhanced Locale Management

Improved locale handling with async support and automatic locale loading:

import { forma } from '@formajs/mold';

// Synchronous locale setting (optimistic)
forma.setLocale('pt-BR');

// Asynchronous locale setting with auto-loading
await forma.setLocaleAsync('pt-BR');

// Manual locale loading
await forma.ensureLocale('pt-BR');
forma.setLocale('pt-BR');

📅 Improved Date Validation

Enhanced date validation with built-in ISO-8601 support:

// Now supports ISO dates without additional options
const dateSchema = forma.string().validateDate(); // Accepts "2025-12-04"

// Still supports custom date options
const customDateSchema = forma.string().validateDate({
  min: '2020-01-01',
  max: '2030-12-31'
});

🔄 Migration Guide

From v1.x to v2.0.0

1. Update Dependencies

npm update @formajs/mold@^2.0.0 @formajs/formajs@^2.0.0

2. Locale Changes

Locales are now opt-in. Import the locale module you need:

// Before (v1.x)
import { forma } from '@formajs/mold';
forma.setLocale('pt-BR');

// After (v2.0.0) - Option A: Synchronous
import { forma } from '@formajs/mold';
import '@formajs/formajs/i18n/pt-BR';
forma.setLocale('pt-BR');

// After (v2.0.0) - Option B: Asynchronous
import { forma } from '@formajs/mold';
await forma.setLocaleAsync('pt-BR');

3. New Formatting Methods

Take advantage of the new formatting capabilities:

// Add formatters to your existing schemas
const userSchema = forma.object({
  name: forma.string().trim().validateNotEmpty(),
  email: forma.string().normalizeEmail().validateEmail(),
  phone: forma.string().formatMobileNumber(), // NEW!
  salary: forma.number().formatCurrency(),     // NEW!
});

💡 Usage Examples

Complete User Registration Schema

const registrationSchema = forma.object({
  // Personal Information
  firstName: forma.string().trim().validateNotEmpty().validateLength({ min: 2, max: 50 }),
  lastName: forma.string().trim().validateNotEmpty().validateLength({ min: 2, max: 50 }),
  email: forma.string().trim().normalizeEmail().validateEmail(),
  phone: forma.string().formatMobileNumber({ style: 'international' }),

  // Account Details
  username: forma.string().trim().toSlug().validateLength({ min: 3, max: 20 }),
  password: forma.string().validateStrongPassword(),

  // Demographics
  birthDate: forma.string().validateDate({ min: '1900-01-01' }),
  age: forma.number().validateInt().min(13).max(120),

  // Financial
  salary: forma.number().min(0).formatCurrency({ currency: 'USD' }),
  taxRate: forma.number().min(0).max(100).toPercentage(),

  // Preferences
  tags: forma.array(forma.string().trim().validateNotEmpty()).minLength(1).maxLength(10),
  notifications: forma.object({
    email: forma.boolean(),
    sms: forma.boolean(),
  }),
});

API Request Validation with Formatting

const apiRequestSchema = forma.object({
  userId: forma.string().validateUUID({ version: 4 }),
  amount: forma.number().validatePositive().formatCurrency(),
  timestamp: forma.string().validateDate(),
  metadata: forma.object({
    ip: forma.string().validateIP(),
    userAgent: forma.string().trim(),
  }),
});
