Alveron Middleware Logger

8.0.3 verified Sat Apr 25 auth: no javascript

Logging middleware for the Alveron HTTP client. This package integrates with Alveron (v8+) to provide structured request/response logging. It supports customizable log levels and output formatting. Current stable version is 8.0.3, released under the alveron ecosystem. Key differentiator: lightweight, TypeScript-first, and designed specifically for Alveron's middleware system, unlike generic logging solutions.
