Update Proto

  1. Prerequisite
npm install grpc
npm install grpc-web
npm install protoc

npm i grpc-web

(original link: https://github.com/grpc/grpc-web/tree/master/packages/grpc-web) Download protoc and the protoc-gen-grpc-web protoc plugin. You can download the protoc binary from the official protocolbuffers release page.

You can download the protoc-gen-grpc-web protoc plugin from our Github release page.

Make sure they are both executable and are discoverable from your PATH.

For example, in MacOS, you can do:

$ sudo mv ~/Downloads/protoc-gen-grpc-web-1.0.3-darwin-x86_64 \
  /usr/local/bin/protoc-gen-grpc-web
$ chmod +x /usr/local/bin/protoc-gen-grpc-web

  1. copy proto files from iotex-core master branch to /iotex-antenna/proto/

  2. Run

npm run build-proto
