Title

Beyond the happy path: functional error handling

Description

You and me are optimists. It’s good for morale to visualize how our program is going to go from A to B to C flawlessly, the proverbial happy path. It’s also less code and tests to write. But you also like to enjoy your weekend without being paged at 4 a.m. so those unhappy paths need to be accounted for! And you don’t enjoy staring at spaghetti code…

In this talk we are going to take a look at how functional error handling can help us to not forget unhappy paths and, at the same time, avoid creating an error handling mess. We will see how this approach solved some headaches with data pipelines whose error handling included futures, sequential and concurrent steps, partial and total failures… connected to a paging application.
