git clone https://github.com/LuisCusihuaman/go-hexagonal-http-api

cd go-hexagonal-http-api

# run api with docker compose
docker-compose up -d --build

🏎️ Getting Started

At this time, you have a RESTful API server running at http://localhost:8080/. It provides the following endpoints:

• GET /health: a healthcheck service provided for health checking purpose (needed when implementing a server cluster)
• POST /courses: creates a new course

Try the URL http://localhost:8080/health in a browser, and you should see something like "everything is ok!" displayed.

If you have cURL or some API client tools (e.g. Postman), you may try the following more complex scenarios:

# healthcheck service provided by: GET /health
curl -X GET --location "http://localhost:8080/health" \
    -H "Accept: application/json"
# should return a healthcheck text: 'everything is ok!'

# creates a new course via: POST /courses
curl -sw '%{http_code}' -X POST --location "http://localhost:8080/courses" \
    -H "Content-Type: application/json" \
    -d "{
          \"id\": \"11d365ab-062f-4dff-9277-8474c50d8e12\",
          \"name\": \"Golang course\",
          \"duration\": \"1 month\"
        }"
# should return a http status code: 201

Connect to database

docker-compose exec mysql mysql -u user -ppassword -D backoffice

SELECT * FROM courses;

Show logs
