WishList

A simple project to show how to do a good architecture using gRPC and Protocol Buffers

Application

The application simulate a simple wish list, we can create a list and add/modify/remove items to your wish list and we'll can export your wish list to csv, to import for example to google spreadsheet.

Model

                                          Item
                                  ┌───────────────────┐ 
         WishList                 │ ID                │
  ┌───────────────────┐           │ WishListID        │ 
  │ ID                │           │ Name              │ 
  │ Name              │<---───────│ Link              │ 
  │ Status            │           │ Price             │ 
  └───────────────────┘           │ Priority          │ 
                                  │ Status            │  
                                  └───────────────────┘

Run the application

To compile our proto files on Go, first of all, we must have installed the plugin to the protocol buffer compiler

$ go get -u github.com/golang/protobuf/protoc-gen-go

And obviously the tool to compile our files, protoc

And then we could compile our files

protoc -I proto --go_out=plugins=grpc:internal/net/grpc proto/*.proto

or using our Makefile

make gen-proto

TODOs

• Improve README.md with more info (usage, etc)
• Add unit & e2e testing
• Add more features (use cases)
• Do an extensive code review (and suggest code improvements)
• Implement a real storage
• Apply gRPC best practises
• Improve error handling on gRPC layer
• Add missing GoDoc comments
• Use gateway to expose an HTTP API
• Use middlewares for observability
• Evaluate if id must be provided from outside
