Updating Protobuf and GRPC in Golang

TL;DR: When protobuf updates, all the .protos and deps need to update.

This post is a quick-lookup for how to do that so I’m not googling it every time.


Go Dependencies

Update your relevant go dependencies:

go get -u github.com/golang/protobuf/{proto,protoc-gen-go} && \
go get -u google.golang.org/grpc

Update Protoc

Then (or before) download and install the latest protoc binary: github.com/google/protobuf/releases.

Download the zip, open it, and move the protoc executable file into somewhere on your path.

mv ~/Downloads/protoc-3.0.0-beta-3.1-osx-x86_64/protoc /usr/local

Rebuild where necessary

Rebuild your .protoc files, likely per project.

For me, this means running go generate ./... in each go project’s root directory.
