EGUI gRPC

A minimal example project that contains a client-server gRPC application made with EGUI (Rust) and Go.

NOTE: Works on Ubuntu22.04, not sure about other OSs.

Setup

Client

• Install the Rust development environment

Server

• Install the latest Go version
• Add protoc 21.6 in order to compile the protobuf files (copy the bin file into /usr/bin for proper usage)
• Navigate to server in your terminal and install the protobuf plugins for Golang:

go install google.golang.org/protobuf/cmd/protoc-gen-go
go get google.golang.org/grpc/cmd/protoc-gen-go-grpc
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc

Generate protobuf files

To do this successfully, the protobuf dependencies should be installed as previously described. For the server, position the terminal into proto_messages and execute the following:

protoc --go_out=../backend --go-grpc_out=../backend *.proto

The client should be generated with the build.rs during the application build so no additional steps required.

For more information, you can have a look this blog post.

Run

• Make sure the protobuf files are previously generated
• Navigate to server and execute:

go run .

• To run the EGUI application, navigate to the client folder and type the following:

cargo run --release
