I want to ditch stream-json so hard (needs polyfills in browser, cumbersome to use), but I need only one feature: invoke callback by path (e.g. `user.posts` need to invoke for each post in array) only for complete objects. Is this something that json river can support?

jsonriver's invariants do give you enough info to notice which values are and aren't complete. They also mean that you can mutate the objects and arrays it returns to drop data that you don't care about.

There might be room for some helper functions in something like a 'jsonriver/helpers.js' module. I'll poke around at it.

Please consider it a feature request
