Example gRPC requests

List out gRPC functions supported by a service:

$ grpcurl -plaintext localhost:50051 list jmartin127.traffic.v1.Traffic
jmartin127.traffic.v1.Traffic.GetTravelTime

Retrieve Travel Time:

$ grpcurl -d '{"originAddress": "my house", "destinationAddress": "Lehi"}' -plaintext localhost:50051 jmartin127.traffic.v1.Traffic/GetTravelTime
{
  "travelTime": "660s"
}

Retrieve Current Weather:

$ grpcurl -d '{"address": "lehi"}' -plaintext localhost:50052 jmartin127.weather.v1.Weather/GetCurrentWeather
{
  "tempFahrenheit": 39,
  "precipitationPct": 1,
  "humidityPct": 38,
  "windMPH": 5
}

TODO

1. Finish the presentation
2. Actually hook this up to Google APIs
3. Dockerize protoc tools (protoc-gen-grpc-gateway, protoc-gen-openapiv2, protoc-gen-go, protoc-gen-go-grpc)
