Sample project that includes the following features:

• Go programming language
• CRUD service offering a simple ToDo list
• Interface is defined via protobuf
• Protoc generates
  • gRPC Server
  • REST Gateway
  • Swagger documentation

So in summary the service offers a REST API and a gRPC API from a single definition. The code is compiled for

• amd64
• arm64

and available as a Multiaarch Docker image under the following tags:

ghcr.io/dkrizic/todo-server:latest

The directory /api contains the protobuf definition of the API

todo.proto

All other files are generated or downloaded. The generated can be updated running

./update

The generated files are commited

The server is implemented in Go and can be found in the directory /server It can be locally run using

$ go run server.go
INFO[0000] Creating new server                          
INFO[0000] Serving gRPC on :8080                        
INFO[0000] Service HTTP on :8090                        
INFO[0035] Creating new todo                             id=d93f5341-071b-462b-af6e-d397aafbe206 title="Another todo"
INFO[0035] Getting all todos                             count=1

The server can be configured to use different backends. The default is a simple in-memory backend. More backends to come.

The following ports are used

• 8080 - gRPC
• 8090 - REST

The client user the gRPC API to create and list todos

$ go run client.go 
INFO[0000] Starting app                                 
INFO[0000] Got todo                                      id=d93f5341-071b-462b-af6e-d397aafbe206 title="Another todo"
