This project uses Go version 1.20, protobuffers and kitex (ByteDance's rpc middleware framework)

# verify installation
go version

As this project has multiple main.go files, vscode might not recognize the correct workspace.

The solution is to create a go.work file and run the following commands to add the respective folders.

# in root
go work init
go work use http-server
go work use rpc-server

References: here

go install github.com/cloudwego/kitex/tool/cmd/kitex@latest
go install github.com/cloudwego/thriftgo@latest

go install github.com/golang/protobuf/protoc-gen-go@latest

Pull the images and start the server with docker compose up.

Client -> HTTP Server -> RPC Server -> Redis

Protocol buffers (protobufs) are a way to serialize data in an efficient way, allowing better utilization of network resources.

It is an interface definition language (IDL) that is language neutral. i.e From a single .proto file, you can easily generate Go, Java, Python code with the code generation features.

idl_http.proto defines the API request and response types.
