Remove Unused bindings for Annotations Imports?

My .proto file includes imports that are never used by the generated JS client - eg. import google/api/annotations.proto import "protoc-gen-swagger/options/annotations.proto"

I was able to generate the JS client with protoc-get-grpc-web, however, the generated code includes those imports even though they are not used by the client:

var google_api_annotations_pb = require('../../google/api/annotations_pb.js')
var protoc$gen$swagger_options_annotations_pb = require('../../protoc-gen-swagger/options/annotations_pb.js')
// Lint Errors:
>>> var `google_api_annotations_pb` is declared but its value is never read
>>> var `google_protobuf_empty_pb` is declared but its value is never read

Is there something in place to prevent unused bindings from being included in the generated code?

Similar issue with grpc-gateway code gen: https://github.com/grpc-ecosystem/grpc-gateway/issues/310

would love to see some progress on this one, since it’s a really annoying issue

Any updates on this? I’m new to grpc-web, my backend is in go, and I don’t know what to do about this. (e.g. ../../google/api/annotations_pb.js isn’t even a file path that would be within my repo.

Did you work around this somehow @gtalarico ?

I ended up with lines like this in my Makefile:

ls -1 api/pb/*.js | xargs sed -i '/google_api_annotations_pb =/d'
