Open-source alternatives to Angular Reactive Validation

Vue Form Making is a visual form designer for Vue.js that lets you build forms by dragging and dropping components onto a canvas, without writing code. It generates runnable Vue.js code and structured JSON from the visual design, enabling rapid form creation and reuse. The tool provides a complete form-building environment with component configuration, input validation with error messages, live preview, and JSON export for storage or sharing. It supports remote data integration to populate dropdowns and other fields from external APIs, and allows custom Vue components to be registered and use

This repository contains the HTML specification, which defines the core standards for web page structuring, content organization, and document rendering. It establishes the fundamental algorithms for state-machine-based tokenization, tree construction for the document object model, and origin-based security isolation. The specification provides a framework for defining custom elements with independent lifecycles and registries. It also details the requirements for cross-document communication, session history management, and the synchronization of interface properties with content attributes.

The library offers a complete design system with Tailwind CSS theming, supporting dark mode, custom color palettes, semantic color aliases, and runtime theme switching through CSS design tokens. It includes built-in internationalization for over 50 languages, server-side rendering compatibility, and a Figma kit that mirrors the code components for design-to-development consistency. The library distinguishes itse

CodeIgniter is a PHP web framework built on the Model-View-Controller pattern, designed for building full-stack web applications. It provides a lightweight toolkit with minimal configuration, organizing application logic into controllers, models, and views for clean separation of concerns. The framework includes a fluent query builder for constructing SQL statements programmatically, PSR-4 autoloading with namespace mapping, and a service-based dependency injection container for managing shared class instances. The framework distinguishes itself through its comprehensive set of built-in tools

async-validator is a JavaScript schema validation library and asynchronous data validation engine. It verifies complex object structures and nested arrays by applying recursive rules and non-blocking, promise-based execution to ensure data integrity. The library functions as both an object constraint validator and a data transformation pipeline. It allows for the sanitization, coercion, and formatting of input values through a sequence of functions that run before and after the primary validation process. The engine covers a range of capabilities including recursive nested validation, the en

This library provides a framework for managing form state, validation, and submission logic within applications. It utilizes a centralized state container to track input values and field metadata, ensuring that user interface elements remain synchronized with data through declarative field bindings. The project is distinguished by its cross-platform abstraction layer, which decouples form logic from specific rendering environments. This allows developers to implement consistent validation rules and state management patterns that function identically across both web and mobile applications. T

Formtastic is a Ruby on Rails plugin designed to automate the creation of semantic and accessible web forms. By mapping database models directly to form fields, the library generates structured HTML markup that adheres to accessibility standards, ensuring that labels and inputs are correctly associated for assistive technologies. The library utilizes a domain-specific language to abstract complex form structures into concise method calls. It distinguishes itself through a metadata-driven approach that inspects database schemas and validation rules to automatically select appropriate input typ

Backbone.validation is a JavaScript library designed to enforce data integrity within Backbone.js models. It provides a framework for defining declarative validation schemas that intercept attribute changes, ensuring that data meets specified business requirements before it is committed to the model. The library distinguishes itself by tightly coupling model-level validation with user interface components. It features an event-driven binding system that monitors model states and automatically triggers interface updates, providing real-time feedback as users interact with forms. This approach

This library is a PHP framework designed for validating and sanitizing incoming data. It provides a structured approach to ensuring that information conforms to expected formats and integrity requirements before it is processed or stored by an application. The project utilizes a fluent interface to construct validation logic, allowing for the definition of complex rules through chainable methods. It employs a strategy-based execution model where individual validation components are encapsulated and can be dynamically assigned to data fields. When validation fails, the system uses an exception

ihp is a type-safe web framework and full-stack application orchestrator designed for PostgreSQL. It functions as a server-side rendering framework and a type-safe ORM that automatically generates record types from SQL schemas to ensure compile-time query validation. The platform distinguishes itself by verifying routing, database queries, and templates at compile time to prevent runtime crashes. It implements real-time web interfaces using WebSockets for instant data synchronization and employs server-driven hypermedia for partial DOM patching. The framework covers a broad range of integrat

An Angular library for form control validation and error handling

oop-validator is a versatile and robust validation library designed to seamlessly integrate with any UI framework or library. Whether you're building applications with Vue.js, React, Angular, or any other front-end technology, oop-validator provides a comprehensive and flexible solution for all your validation needs.

This project is a jQuery-based form validation library designed to verify HTML form input values on the client side before submission. It functions as an input validator that enforces data integrity constraints through rule-based verification and value normalization. The library focuses on web accessibility compliance by linking error messages to input fields via ARIA attributes, ensuring that screen readers can announce validation failures to the user. The system supports the creation of custom validation rules and the transformation of raw input strings through a normalization pipeline. Co

is.js is a JavaScript validation library and data type checker. It provides a suite of utilities to verify whether variables are primitives, arrays, functions, or specific object types. The project allows for the implementation of custom validation logic and the use of naming namespaces to override default rules and regular expressions. It covers a broad range of validation capabilities, including numeric arithmetic properties, date and time analysis for relative and absolute ranges, and string format verification for patterns such as emails, URLs, and IP addresses. The library also includes

validator.js is a JavaScript string validation and sanitization library. It provides a set of functions to verify that strings match specific patterns—such as emails, URLs, and alphanumeric formats—and a toolkit for cleaning and transforming text input to remove prohibited characters and trim whitespace. The library includes utilities for standardizing email addresses by lowercasing domains and removing sub-addressing markers. It also functions as an HTML entity escaper, replacing special characters with entities to prevent the browser from executing text as code. The project covers capabili
