Open-source alternatives to SwiftValidator

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

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

Pothos is a code-first GraphQL schema builder and framework designed for type-safe development. It allows developers to construct schemas using typed definitions in TypeScript, eliminating the need for external code generation steps. The framework distinguishes itself through a dedicated data mapper that connects GraphQL types to relational databases and ORMs, such as Prisma, while optimizing query resolution. It provides a full implementation of the Relay specification, including global object identification and cursor-based pagination. The project covers several core capability areas, incl

ozzo-validation is a programmable data validation library for Go that verifies structs, maps, and primitive types using a declarative, rule-based approach. It functions as an interface-based validator, allowing for the recursive checking of nested data structures and custom types without the use of struct tags. The framework distinguishes itself as a context-aware validation engine, supporting the propagation of request-scoped data to rules that depend on external state. It provides extensive extensibility through custom rule definitions and the ability to override default failure text with l

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

PhoneNumberKit is a Swift framework for parsing, formatting, and validating international phone numbers according to global numbering standards. It provides a system of lookup tables, structural parsers, and validation tools to handle the complexities of international telephone numbering. The library converts raw strings into structured objects containing country codes and national numbers. It translates international dialing codes into full country names and verifies whether phone number strings are logically possible and conform to specific regional numbering plans. The project includes ut

Eureka is a framework for building structured data-entry interfaces and forms in Swift for iOS applications. It provides a declarative UI layout engine and a dynamic input interface to define fields, sections, and row layouts through a configuration layer. The system distinguishes itself through dynamic interface management, including conditional visibility and interaction control that reacts to real-time user changes. It supports complex input behaviors such as expandable row rendering, multivalued field management for inserting or deleting similar rows, and custom keyboard navigation that s
