# order-service-clean-arch * **Portuguese Version: [README_ptBR.md](https://github.com/carloseduribeiro/order-service-clean-arch/blob/master/README)** This repository contains a project developed during the Clean Architecture module of the GoExpert course by FullCycle. ## How to Execute de project ```shell # Run the database and RabbitMQ server in docker: docker compose up -d # Run the application: cd cmd/orderSystem && go run main.go wire_gen.go ``` ## Description order-service-clean-arch is a simple application that was developed using the Clean Architecture principles. It provides three services: * **HTTP Server**: porta ```80``` * **gRPC**: porta ```50051``` * **graphQL**: porta ``4000`` ### HTTP Server It has two resources at an endpoint: 1. Create order: ```POST /order```; 2. List order: ```GET /order```. Both resources are defined on [api](https://github.com/carloseduribeiro/order-service-clean-arch/blob/master/./api) folder at root path of the project. ### gRPC We are using [gRPC-go](https://github.com/carloseduribeiro/order-service-clean-arch/blob/master/https://pkg.go.dev/google.golang.org/grpc) implementation of [gRPC](https://github.com/carloseduribeiro/order-service-clean-arch/blob/master/https://grpc.io/) for communication by RPC with [Protocol Buffers 3](https://github.com/carloseduribeiro/order-service-clean-arch/blob/master/https://protobuf.dev/programming-guides/proto3/). You can use the [Protocol Buffer Compiler](https://github.com/carloseduribeiro/order-service-clean-arch/blob/master/https://grpc.io/docs/protoc-installation/) to parse and compile the ```.proto``` file, witch contain service and message definitions. See gRPC [Quick Start](https://github.com/carloseduribeiro/order-service-clean-arch/blob/master/https://grpc.io/docs/languages/go/quickstart/#prerequisites) guide for more information. If you want to change this project, you can parse and compiling the ```.proto``` file with the following command: ```shell protoc --go_out=. --go-grpc_out=. internal/infra/grpc/protofiles/order.proto ``` You can use **[Evans gRPC Client](https://github.com/carloseduribeiro/order-service-clean-arch/blob/master/https://github.com/ktr0731/evans)** to make RPCs. It lists the services provided by our gRPC server friendly. ### GraphQL ### google-wire We are using the [dependency injection](https://github.com/carloseduribeiro/order-service-clean-arch/blob/master/https://stackoverflow.com/questions/130794/what-is-dependency-injection) design principle. In practice, that means we pass in whatever each component needs. This style of design lends itself to writing easily tested code and makes it easy to swap out one dependency with another. One downside to dependency injection is the need for so many initialization steps. Wire make's the process of initializing our components smoother. See Wire's docs: https://github.com/google/wire/tree/main The file ```cmd/orderSystem/wire.go``` contains the initializer definitions to generate Wire's code.
