Valibot is a modular, type-safe schema library for validating and parsing structural data in TypeScript environments.
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
Yup is a JavaScript schema validation library used to define data shapes and validate runtime values. It functions as an object schema validator and a data coercion engine, allowing developers to transform raw input values into desired types before performing validation checks. The library is distinguished by its support for dynamic schema validation, where rules can be adjusted at runtime based on sibling field values or external context. It also enables recursive data structuring for polymorphic fields and provides a system for extracting static TypeScript interfaces from runtime schema def
This project is a protocol buffer validation plugin and code generator that creates consistent validation logic across multiple programming languages. It functions as a compiler extension for the Protocol Buffer toolchain, allowing developers to define semantic constraints directly within schema files to ensure data consistency. The tool uses custom options to embed validation rules into message definitions, mapping these schema constraints to language-specific implementation patterns. It employs predicate-based constraint checking and recursive traversal to enforce rules across nested messag
prop-types is a JavaScript object validator and runtime type checker. It serves as a development tool for verifying that object properties match predefined specifications, primarily used to ensure that data passed into React components aligns with expected types.
The main features of facebook/prop-types are: Runtime Type Validation, Type Specification Matching, JavaScript Object Validation, Runtime Type Checkers, Data Type Validation, Object Shape Validation, Recursive Object Validation, Object Validations.
