go-tax-project

• CRUD example with SOLID, interfaces, and good practices using GoLang.
• RabbitMQ to receive messages on "Order" queue and save on SQLite3, using channels.

DOCKER steps

Before starting prepare your image, execute this docker steps:

docker build -t [YOUR_USER]/go-tax-project .
docker push [YOUR_USER]/go-tax-project

Create table orders

sqlite3 db.sqlite3
sqlite> CREATE TABLE orders (id VARCHAR(255) NOT NULL, price float NOT NULL, tax float NOT NULL, final_price NOT NULL, PRIMARY KEY (id));

Run docker compose to start RabbitMq server

docker-compose up -d

Creating and publishing message on the queue

Open web browser http://localhost:15672/ and create a queue called 'order', so publish the following json

{"id": "3", "price": 10.0, "tax": 0.2}
{"id": "2", "price": 20.0, "tax": 3.2}
{"id": "3", "price": 45.0, "tax": 1.2}

Running

To run the main.go program: go cmd/order/main.go
If you need debug code, might it run nodemon comand to watch changes

nodemon --exec go run cmd/api/main.go --signal SIGTERM
