I’m sad to see that microservices are falling in popularity among architects and developers. Some say they are unnecessarily complex or overengineered. That one needs to learn so many new tools and technologies. That they introduce problems we had already solved. However, many ‘do microservices’ (unintentionally) wrong…
When documenting APIs, developers often link to ISO 8601 as the standard for computer-readable date and date-time format. Dates and times (and time zones!) are complicated. There are so many edge cases and pitfalls. I’m sure every developer has a battle story about them. It’s good to delegate that hard work to somebody else. So when an international body that everybody knows and trusts publishes such a standard, it’s no surprise all the API designers start referring to it.
When I was working on my small side-project library, I needed to represent a missing value. In the past, I’d used the nullable approach in simple settings and Option (aka Maybe) when I wanted more control. In this case neither felt correct so I came up with a different approach I’d like to present.
