Typia is a compile-time code generator that transforms TypeScript type annotations into runtime validation, serialization, and schema functions without requiring decorators or separate schema files. It generates optimized validation and serialization code during TypeScript compilation, producing dedicated functions for each type that eliminate runtime schema objects for faster execution. The project extends this core capability into several integrated areas. It generates fully typed client SDKs from NestJS controller source code, keeping server and client types synchronized automatically. It

ow is a type-safe schema validation library for TypeScript that verifies data integrity at runtime. It functions as a runtime validation framework and type guard utility, ensuring that JavaScript values match expected types and schemas before they are processed. The library synchronizes runtime data checks with static TypeScript type definitions, allowing users to extract type definitions directly from validation predicates. This integration enables type narrowing, where a successful validation result refines the variable type for safer usage in the code. The framework uses a chainable API t

This project is a thread-safe, asynchronous logging library designed for C++ applications. It provides a comprehensive diagnostic toolkit that enables developers to record system events, track execution flow across multiple threads, and manage log output through severity-based filtering and automated file maintenance. By offloading log formatting and disk input/output to background worker threads, the library minimizes latency on the main execution path, ensuring high performance in time-critical systems. The framework distinguishes itself through its flexible configuration and diagnostic cap
