alt Hacker NewsI've gone the all-JSON route many times, and pretty soon it starts getting annoying enough that I lament not using protos. I'm actually against static types in languages, but the API is one place they really matter (the other is the DB). Google made some unforced mistakes on proto usability/popularity though.
why are you against static types in languages?
I once converted a fairly large JS codebase to TS and I found about 200 mismatching names/properties all over the place. Tons of properties we had nulls suddenly started getting values.
