> Specifically, the article talks about how parsing JS is more costly than JSON - this cost will apply to the protobuf library which certainly far exceeds 10KB.

I would suggest reading the links I posted. The minimal protobuf library, which is suitable for working with static decoding, is 6.5KB [1]. Again, you're right that the size of the protobuf library will be an important factor in dictating the scale at which it's more effective than JSON parsing but your sense of the factors is off - a light protobuf library doesn't reach 10kB let alone "far exceeds 10KB".

Furthermore, if your pages use the protobuf library already for other uses like decoding and encoding RPC messages then loading and parsing the protobuf library is basically free - you're going to be doing this anyway.

I currently work on a project using protobufjs. Our generated static classes are ~500KB and ~1.5MB, or around 140KB gzipped. The schemas are not that large, and this does not even include any network code (not part of protobufjs).
