# Code-style
- methods that return a promise should always use async/await
otherwise synchronous errors can get swallowed
you can return a promise without awaiting it though.
- only named exports, no default exports
otherwise it becomes hard to remember what was a default/named export
- should we return promises from storage mutation calls? probably not, as we don't await them anywhere. only read calls should return promises?
- we don't anymore
- don't use these features, as they are not widely enough supported.
