gRPC to HTTP streaming examples

Examples to convert gRPC tonic stream to HTTP stream (SSE).

How to run

To no build when running, you can build the project first:

cargo build

gRPC tonic server

cargo run --bin grpc_server

Will start the gRPC server on localhost:50051 by default.
This can be changed with env variables APP_HOST and APP_PORT.

Axum HTTP server

GRPC_URI="localhost:50051" cargo run --bin axum_server

Will start the gRPC server on http://localhost:3000/ by default.
This can be changed with env variables APP_HOST and APP_PORT.
And you can change the gRPC server URI with the env variable GRPC_URI.

You can then test with curl:

curl http://localhost:3000/

Notes

Note

I didn't find solutions to handle errors when dealing with stream on the HTTP SSE side... If anyone has a solution for this, feel free to let me know.
