A lightweight, modular HTTP server framework for Node.js and Bun built with TypeScript. This is a framework project, not an API or application. The code here is meant to be used by other developers to build their own applications.
YinzerFlow is designed for developers who want:
- Security-first — Built-in protections against common web vulnerabilities
- TypeScript-first — Full type safety and IntelliSense support (JavaScript is supported natively)
- Pittsburgh personality — Witty logging and error messages
- Flexible configuration — Comprehensive options for different use cases
- Modular architecture — Scales from simple APIs to complex applications
