Zend Expressive

Expressive 2.0 introduced a new method to handle errors, using listeners to the ErrorHandler and delegator factories, so this is the preferable method.

HttpLog Middleware

It will log requests and responses in compact or full mode. It will include X-Request-Id and X-Response-Time headers if present.

Zend Expressive
