Hapi 17 was released a while back with quite a few nice improvement – mostly centered around using promises instead of callbacks and thus fitting in with async/await well.  However, it’s a very significant change right across it’s APIs so it took quite a while for the various plugins that Moolah uses to be updated.

Eventually though they were all ready and then the actual upgrade of Moolah code was pretty straight forward.  Moolah had been using async handlers via a plugin all along so there were minor changes to how they were specified but very few changes to the control flow they then used.

In the end it only took an evening’s work to get it all upgraded and I haven’t encountered any bugs since. That’s a pretty good vote of confidence in the effectiveness of it’s tests.

The next big upgrade will be to move the front-end over to WebPack v4. The improvements there look excellent, removing a lot of the previously required config and simplifying things but that also means it’s a pretty complex migration.
