# 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

```bash

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

```bash

make all

```

It should create two binaries `server` and `client`

## Use

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

Client output example:

```bash

./client

2017/12/01 14:16:55 0 sent

2017/12/01 14:16:55 4 sent

2017/12/01 14:16:55 new max 4 received

2017/12/01 14:16:55 0 sent

2017/12/01 14:16:56 6 sent

2017/12/01 14:16:56 new max 6 received

2017/12/01 14:16:56 3 sent

2017/12/01 14:16:56 2 sent

2017/12/01 14:16:56 finished with max=6

```

Server output:

```bash

./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

2017/12/01 14:16:55 send new max=4

2017/12/01 14:16:56 send new max=6

2017/12/01 14:16:56 exit
