io-ts is a powerful and expressive library for runtime type checking and decoding of data objects in TypeScript. It allows you to define your data types as composable runtime values that can be used to validate any data object you receive (from API responses, configuration files, etc.) and decode it into a TypeScript value.
Compared to other libraries like PropTypes or interface validation, io-ts provides a more robust solution as it allows for complex validations while keeping them easy to express and compose. io-ts leverages tag-based unions to make working with even the most complex data structures simple and clear. It supports inheritance, composition, interfaces, and can be extended easily.
Alternatives: PropTypes, Joi, class-validator
