- My first project was with golang, so this project simulates microservice for orders. Imagine you have an e-commerce and receive multiples payments orders, these requests need passing for multiple businesses so for improving these processes you need to build two services. The first process is a publisher, only pulled orders request in queue for another service (Consumer) make the all business logic for making this processes complete. In consumer, imagine if you need to calculate a final price for each order based on delivery tax this business logic is calculated by the consumer.
- Golang: programming language
- Rabbitmq: Queue manager
- Grafana: Dashboard statistic
- Prometheus: For Monitoring the rabbitmq
- sqlite3: Database
- First need golong installed, afeter dowload goland need rung
go mod tidy- After this, you need docker to run the docker compose for rabbitmq, grafana, and prometheus.
docker compose up -d
- Must need to create the orders table in the database so for this run:
sqlite3
CREATE TABLE orders (id VARCHAR(255) NOT NULL, price FLOAT NOT NULL, tax FLOAT NOT NULL, final_price FLOAT NOT NULL, PRIMARY KEY (id));
- Finally for run the consumer and producer:
go run ./cmd/consumer/main.go
go run ./cmd/producer/main.go
