unzip protoc-3.9.0*.zip

sudo mv bin/protoc /usr/local/bin

wget https://github.com/grpc/grpc-web/releases/download/1.0.5/protoc-gen-grpc-web-1.0.5-darwin-x86_64

chmod +x protoc-gent-grpc-web*

sudo mv protoc-gen-grpc-web* /usr/local/bin/protoc-gen-grpc-web

```

#### Linux

```sh

wget https://github.com/protocolbuffers/protobuf/releases/download/v3.9.0/protoc-3.9.0-linux-x86_64.zip

unzip protoc-3.9.0*.zip

sudo mv bin/protoc /usr/local/bin

wget https://github.com/grpc/grpc-web/releases/download/1.0.5/protoc-gen-grpc-web-1.0.5-linux-x86_64

chmod +x protoc-gent-grpc-web*

sudo mv protoc-gen-grpc-web* /usr/local/bin/protoc-gen-grpc-web

```

### Install Go dependencies

```sh

cd server

make setup

```

### Install Javascript dependencies

```sh

cd web

npm i

```

## Running

```sh

make containers  # docker-compose up -d

```

You can serve and point browser to `web/index.html` or use grpcurl:

```sh

grpcurl -proto proto/ecommerce.proto -plaintext -v localhost:8080 ecommerce.ProductService/ReadAll

```

## Generate self signed certificate

```sh

# Using Go

go run $GOROOT/src/crypto/tls/generate_cert.go --host mydomain.io

# Using OpenSSL

openssl req -nodes -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365

```
