formSeu

formSeu is a software library designed to simplify the creation, validation, and submission of web forms. It emphasizes a framework-agnostic, modular approach that lets developers define forms as schemas and enforce rules consistently across client and server boundaries.

Core concepts include a form schema, field definitions, and a set of reusable validators. The core provides data binding, type coercion, and centralized error collection, while a plugin system enables custom validators, formatting, and submission handlers.

Rendering is decoupled from form logic through adapters that connect the core to user interfaces built with frameworks such as React, Vue, or plain HTML. It supports asynchronous validation, accessibility features, internationalization, and basic security measures like CSRF-aware submission.

Usage generally involves defining a schema for the desired fields, attaching validators, rendering the form through a UI adapter, and handling submission via a standardized API that returns structured error data when validation fails.

History and reception: formSeu originated in a community-driven project aiming to provide a consistent form experience across applications. It has been adopted in several production environments and is often discussed alongside other schema-based form libraries for its clarity and extensibility.
