Koa Logger Middleware

Koa-logger is a development-style logging middleware for Koa.js applications, providing colorful, concise HTTP request and response logging to the console. The current stable version, 4.0.0, was released after a period of lower activity, signaling a revival of the project and bringing support for Koa v3 and Node.js versions 18 and higher. It outputs request method, URL, response status, duration, and content length, often formatted with ANSI colors for readability. A key differentiator is its customizable `transporter` option, which allows developers to redirect log output to alternative pipes or logging systems, rather than just `process.stdout`. While primarily a CommonJS package, its updates ensure compatibility with modern Node.js environments and Koa framework versions.
