How to make protobufjs generated code smaller

Question

protobufjs generated code is too large for front end cases in mobile cases. There is about 300kb while using 3 short proto files.

Bash for generating es6:

pbjs -t static-module -w es6 -o proto.js titan.proto --no-convert --no-delimited --no-comments

Answer 1
