Monolith Database and Services

Use this skill when

  • •Modifying DB initialization or model migration behavior.
  • •Implementing external integrations in app/services/.

Database flow

  • •Initialized by db.InitDB().
  • •Uses GORM with SQLite driver by default.
  • •AutoMigrate runs for registered models at startup.

Model registration rule

Any new model must be included in db/db.go AutoMigrate call. The model generator handles this automatically.

Services pattern

  • •Service code belongs under app/services/ (e.g., app/services/email).
  • •Keep HTTP controllers thin; push external API logic into services.
  • •Source environment settings from app/config/config.go.

Email specifics

  • •Uses MAILGUN_DOMAIN, MAILGUN_API_KEY, and MAILGUN_API_BASE.
  • •Missing mail variables are warned by config init.
