Suggested Changes
One of the particularly exciting changes in our upcoming v8 version is us finally fixing up messaging around the {} (empty object type). It's long been a contentious part of the ban-types rule:
- On the one hand,
{}is a confusing type that a lot of TS devs get tripped up over - On the other hand, there are legitimate use cases for it, and banning it outright is too string
We think we've reached a good compromise for v8 with the combination of:
- For
{}, splitting out a dedicatedno-empty-object-typerule: Enhancement: [ban-types] Split the {} ban into a separate, better-phrased rule #8700 -> feat(eslint-plugin): split no-empty-object-type out from ban-types and no-empty-interfaces #8977 - For the remaining uses of (a) configurable types and (b) uppercase aliases like
Number, splitting out a couple of rules: Enhancement: [ban-types] Split into default-less no-restricted-types and more targeted type ban rule(s) #8978 -> feat(eslint-plugin): replace ban-types with no-restricted-types, no-unsafe-function-type, no-wrapper-object-types #9102
This has been a long journey with lots of discussion (#8700 is just one of many!). It seems ripe for a blog post to me!
