mopForms

mopForms is a modular web form framework designed to simplify the creation of complex forms in modern web applications. It provides a collection of components and utilities for rendering, validating, and submitting forms, with a focus on accessibility, extensibility, and developer experience.

Forms in mopForms are defined declaratively via configuration objects or schemas. The framework supports a wide range of field types, validation rules, conditional logic, and dynamic or multi-step workflows. It emphasizes accessible semantics, proper error messaging, keyboard navigation, and compatibility with screen readers. Validation can be synchronous or asynchronous and can cross-check related fields.

Architecturally, mopForms uses a component-based core with a form container and reusable field components. Form state is centralized, enabling serialization, persistence, and reset. The core is framework-agnostic, with adapters or integrations for popular ecosystems, including React, Vue, and vanilla JavaScript environments.

Key features include a plugin system for theming and localization, a JSON-schema-like approach to define forms, built-in validators, and extensible submission handlers. It supports custom widgets, internationalization, and accessible error presentation. Developers can extend mopForms through plugins to integrate with backend APIs, analytics, or custom data stores, while maintaining consistent form behavior.

mopForms is maintained by a community-driven open-source project with documentation and examples available online. The project aims to standardize form building and reduce boilerplate across web applications.
