Developing

If you cloned the repository locally ensure that you have go 1.20 installed. To install the dependencies run the following command:

go mod download

After installing the dependencies you need to populate a local .env file in the root directory with the following variables:

# DEV:    For local development
# DOCKER: For builds with docker-compose
# PROD:   For prod builds or previews
ENVIRONMENT=DEV or DOCKER or PROD

# Secret key for generating JWT tokens
JWT_SECRET="some super long and secure secret"

# For dev database connection
DEV_DB_HOST=localhost
DEV_DB_PORT=5432
DEV_DB_USER=admin
DEV_DB_PASSWORD=password
DEV_DB_NAME=travel_expenses-db

# For docker network database connection
DOCKER_DB_HOST=expense-db-container
DOCKER_DB_PORT=5432
DOCKER_DB_USER=admin
DOCKER_DB_PASSWORD=password
DOCKER_DB_NAME=travel_expenses-db

# For prod database connection
PROD_DB_HOST=ask luca
PROD_DB_PORT=ask luca
PROD_DB_USER=ask luca
PROD_DB_PASSWORD=ask luca
PROD_DB_NAME=ask luca

# Mail Server
MAILGUN_API_KEY=ask kevin
MAILGUN_DOMAIN=mail.costventures.works

For the dev-enviroment you will also need a local postgres cluster running on port 5432 with the credentials as specified in the example above. The database itself should be setup with the expense_db.sql file in the root directory of this repository. More information on how to do this can be found here.

Building

To run the application in a local container run the following command:

bash ./scripts/start
# exposed at localhost:8081

To stop the container run the following command:

bash ./scripts/stop

To run the application locally without a container run the following command:

go run ./...
# exposed at localhost:8080

Contributing

To contribute to this template, clone this repository locally and commit your code on a separate branch. Try using conventional commits. When you're ready to submit your PR, check if your application builds by running the following commands:

go build ./...

Finally check if you can build and run the container:

bash ./scripts/start

If the checks pass open a pull request on the main branch. Once the pull request is approved and merged, your changes will be automatically deployed to production.
