It would be great if we could always keep our users in the happy path. But the best apps are those that deal properly with any unexpected situations. In this talk I will dive deep into the details of error handling.
I will try to answer to the following questions that you may have asked yourself while developing your apps:
- When should I use errors (versus other options like a simple optional)?
- How do I implement errors to get the most out of them?
- What should I take into account in an advanced architecture regarding error handling? When and how do I do error translation?
- What is the proper implementation if I want to go functional? How to avoid partial functions?
