Product service

Product listing for your ecommerce store.

The figure below depicts how the solution was architected:

and below how the source code was structured:

.
├── api
├── cmd
├── entity
├── grpc
├── mocks
├── postgresql
├── product.go
└── usecase

• api: gRPC protocol definition.
• cmd: Command line interfaces like daemons and clients.
• entity: Internal only data structure representation.
• grpc: gRPC generate stubs and server implementation.
• postgresql: Postgresql data store implementation.
• product.go: Interfaces definitions.
• usecase: Use cases implementations.

The main reason for this is to build a solution to middle-to-long tream.

Requirements

• Golang
• Postgresql

Local development

Clone:

git clone https://github.com/wiliamsouza/product.git

The recomended way to get it is through https://github.com/wiliamsouza/maketplace

Install dependencies:

make deps

Build binaries:

make build

This will build two commands:

• productctl: Command line interface.
• productd: Start gRPC and HTTP servers.

Generated in dist folder for Linux and Mac.

Each command has it own help:

$ dist/productd_linux_amd64/productd 
Product is a gRPC and HTTP service daemons that implements products listings.

Usage:
  productd [command]

Available Commands:
  help        Help about any command
  serve       Start http or grpc daemons
  version     Print version

Flags:
      --config string   config file (default is $HOME/.product.yaml)
  -h, --help            help for productd

Use "productd [command] --help" for more information about a command.

and:

$ dist/productctl_linux_amd64/productctl 
Productctl is a client for product gRPC service that implements products listings.

Usage:
  productctl [command]

Available Commands:
  client      Interact with product gRPC server
  help        Help about any command
  version     Print version

Flags:
      --config string   config file (default is $HOME/.product.yaml)
  -h, --help            help for productctl

Use "productctl [command] --help" for more information about a command.

Testing

make test

Makefile

Run make to see help.

help                           Show Help
security                       Run security code checks
typping                        Run static type checker
lint                           Run lint
check                          Run pylint, mypy and bandit
test                           Run tests

Database

First install https://github.com/golang-migrate/migrate/tree/master/cmd/migrate

This command bellow will create product table.

make migrate

Before run migrate start database:

docker-compose up

Docker

Build:

docker build -t product .

Run:

docker run --rm product
