Reference Project weather-rpc,It based on Scala 2 and cats 1, and does not use fs2-grpc and sangria

A web server that allows to get the current temperature at most of the big cities in the world.

• Scala 3
• cats-effect 3
• fs2-grpc
• http4s
• circe
• sangria

• You need to run the server app. Go to the project dir and execute

sbt "weather-server/runMain bitlap.weather.server.WeatherApplication"

There are 2 clients in the project:

1. a simple client that gets the temperature for a single city and sends a shutdown server command
2. a streaming client that gets the temperature for multiple cities in a stream mode. This client does not stop the server.

To run the simple client execute

sbt "weather-client/runMain bitlap.weather.client.SimpleWeatherClient"

To run the streaming client execute

sbt "weather-client/runMain bitlap.weather.client.StreamingWeatherClient"
