Getting started

1. Setting up environment variables (create a .env file in the project root):

# Database
export DB_HOST=
export DB_PORT=
export DB_USER=
export DB_NAME=
export DB_SSLMODE=
export DB_PASSWORD=

# Local database
export LOCAL_DB_PORT=

# Postgres service
export POSTGRES_PASSWORD=

# Password Hasher
export HASH_SALT=
export HASH_SECRET=

# GIN mode (optional, default - release)
export GIN_MODE=

Hint: if you are running the project using Docker, set DB_HOST to "postgres" (as the service name of Postgres in the docker-compose).

2. Compile and run the project:

make

3. To test the service's functionality, you can navigate to the address http://localhost:8080/docs/index.html to access the Swagger documentation.

Hint: to complete the authorization in Swagger UI after receiving the JWT token, you need to enter Bearer <your_token> (without "<" and ">" symbols) in the input field.
