@mito-forms/core

Mito Forms Core is the lightweight, framework-agnostic core engine for building dynamic, state-managed forms.
It provides a highly flexible and minimalistic foundation for form state management, input validation, and dynamic updates — without forcing any specific UI framework or heavy dependencies.

This package powers Mito Forms' modular architecture, allowing it to adapt easily to various UI libraries (e.g., React, Material UI, Bulma, Bootstrap) while keeping your form logic cleanly separated from your components.

Features

• 🚀 Lightweight: Minimal runtime footprint with no external UI dependencies.
• 🔄 Dynamic Forms: Supports dynamic field updates, conditional logic, and computed fields.
• 🗋l Validation Engine: Built-in support for synchronous and asynchronous validation.
• 🧹 Composable: Cleanly separate form state, field definitions, and validation logic.
• 🛠️ Framework-Agnostic: Integrates easily with React, Vue, Angular, or any rendering system.

Installation

npm install @mito-forms/core
# or
pnpm add @mito-forms/core
# or
yarn add @mito-forms/core

Core Concepts

• Form State — Central store for all fields and their metadata (values, errors, touched status, etc.)
• Field Definitions — Define initial values, validators, and dynamic behaviors.
• Validators — Built-in rules like required, email, minLength, and ability to add custom ones.
• Subscriptions — Listen reactively to form or field-level changes.
