If it really is a problem, then another option is to use Protobus or Message Pack for serializing (maybe into base64?).

Chances are, your world state really isn't large enough to warrant splitting it up into "different layers". Even if it kind of was, there's much more sensible ways of reducing the size of your packets. Like you're probably using JSON, which again is probably still fine, but it's far from an optimized way of serializing data. Here's what I mean: https://github.com/mtth/avsc/wiki/Benchmarks

That being said, when JSON serialization should indeed fail, the library above might also be useful as it provides additional insights into why it did fail: specific property path and value, and reason why it failed. I have written a [second library `is-json-value`](https://github.com/ehmicky/is-json-value) which makes it convenient to generate a list of warning messages indicating why a value is not JSON-safe.
