Scala gRPC

POC of gRPC with Scala & NodeJS languages

Simple chat service using bi-directional streaming

Requirements

• Java 8
• sbt 0.13.13

Usage

Generate code from protobuf files

Run the following commands:

sbt
project domain
compile

(Running the client or the server will generate sources too)

Run Server

Run the following commands:

sbt
project chat-grpc-server
run

Run Scala Client

Ensure server is running. Then run the following commands:

sbt
project chat-grpc-client
run

you can run multiple Java clients simultaneously

Run Electron Client

See dedicated README

Reason

Have a closer look at gRPC:

• Validate ease of use
• Validate cross languages code generation
• Implement bidirectional streaming

TODO

• add support for image message type
• add support for WhatsApp message types
