Zend Framework Blog:
Error Handling in Expressive
Mar 24, 2017 @ 09:30:31

The Zend Framework blog has a new tutorial posted by Matthew Weier O'Phinney covering error handling techniques in Expressive with a few examples making use of some custom middleware and logic.

One of the big improvements in Expressive 2 is how error handling is approached. While the error handling documentation covers the feature in detail, more examples are never a bad thing!

In their example they're creating an API resource that returns a list of book details (ones the user has read). The goal is to use the existing error handling for everything except the custom exceptions they want to throw but keep with the JSON handling throughout. First the middleware to handling the API request is shown, complete with sorting and pagination. Then come the custom exception examples for invalid requests and server issues. These exceptions are then put into the Problem Details format with the help of another middleware. This then all tied together with the nested middleware handling Expressive provides and an example of the end result is included.
