# gRPC Calculator

Simple gRPC calculator implementation with SSL, login and headers interceptors.

**gRPC Unary**:

- `rpc Sum(SumRequest) returns (SumResponse);`

- Error Handling: `rpc Sqrt(SqrtRequest) returns (SqrtResponse);`

**gRPC Server Streaming**:

- `rpc Primes(PrimesRequest) returns (stream PrimesResponse)`

**gRPC Client Streaming**:

- `rpc Average(stream AverageRequest) returns (AverageResponse)`

**gRPC Bidirectional**:

- `rpc Max(stream MaxRequest) returns (stream MaxResponse)`

## Usage

1. Install protobuf go plugins

```bash

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

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

$ export PATH="$PATH:$(go env GOPATH)/bin"

```

2. Compile proto files

```bash

$ cd proto

$ protoc --go_out=. --go_opt=paths=source_relative --go-grpc_out=. --go-grpc_opt=paths=source_relative *.proto

```

3. Uncomment [client/main.go](./client/main.go) with the function to test

```

//DoSum(c, &pb.SumRequest{FirstValue: 1, SecondValue: 1})

//DoSumDeadline(c, &pb.SumRequest{FirstValue: 1, SecondValue: 1}, 5*time.Second) // no error

//DoSumDeadline(c, &pb.SumRequest{FirstValue: 1, SecondValue: 1}, 1*time.Second) // timeout error

//DoPrimes(c, 400)

//DoAverage(c, []float64{1, 2, 3, 4})

//DoMax(c, []int32{1, 5, 3, 6, 2, 20})

//DoSqrt(c, -9)

```

4. Generate certs

```bash

$ cd ssl

$ bash generate-certs.sh

```

5. Compile server and client

```bash

$ cd ..

$ go build -o server/server server/*.go

$ go build -o client/client client/*.go

```

6. Run server and client

```bash

# Run server

$ ./server/server

# Run client on another terminal

$ ./client/client

```
