Golang gRPC bidirectional streaming example

  • client sends random numbers to server
  • server receives number and sends it back if the number greater than all previous numbers
  • both client and server handle context errors (try to close client during send)

Requirements

  • go 1.17.1
  • protobuf installed
  • go support for protobuf installed

Installation

MacOS

brew install go
brew install protobuf
go install google.golang.org/grpc/cmd/[email protected]

Make sure protoc-gen-go added in PATH

To add it to PATH you can use bash profile for example.

Edit vim ~/.bash_profile, add: export PATH="$PATH:$(go env GOPATH)/bin", run source ~/.bash_profile to apply changes.

Linux

TBD

Complie

make all

It should create two binaries server and client

Use

Start server ./server and in other terminal start ./client

Client output example:

./client

./server
2017/12/01 14:16:54 start new server
2017/12/01 14:16:54 send new max=1
2017/12/01 14:16:55 send new max=2
