Overview
gRPC
gRPC is a transport mechanism for request/response and (non-persistent) streaming use cases. See Why gRPC? for more information about when to use gRPC as your transport.
gRPC APIs are useful instead of (or as a complement to) JSON/REST-based API.
Pekko gRPC
Pekko gRPC provides support for building streaming gRPC servers and clients on top of Pekko Streams and Pekko HTTP.
It features:
- A generator, that starts from a protobuf service definitions, for:
- Model classes
- The service API as a Scala traitJava interface using Pekko Stream
Source
s - On the server side, code to create a Pekko HTTP route based on your implementation of the service
- On the client side side, a client for the service
- gRPC Runtime implementation that uses
- Pekko HTTP/2 support for the server side and
grpc-netty-shaded
for the client side.
- Support for sbt, gradle, Maven, and the Play Framework.

Project Status
Pekko gRPC is still under development.
Both client- and server-side APIs are based on Pekko Streams.
The client side is currently implemented on top of io.grpc:grpc-netty-shaded.
Later versions may replace this by io.grpc:grpc-core and Pekko HTTP, when Pekko HTTP offers HTTP/2 client support.
