Replace nil email service pattern with NoOpEmailService (Null Object)
to eliminate nil pointer panics across all handlers.
Add /docs route as a shortcut to Swagger UI.
Fix streak calculation returning 0 when server timezone differs from
UTC — CreatedAt was not converted to UTC before date extraction.
- Add structured logging for email sending (success/failure)
- Add HealthCheck method to EmailService interface
- Extend /health endpoint to include SMTP status
- Update all email service mocks to implement HealthCheck
- SMTP status shows: ok, error, or disabled
Implemented comprehensive filtering capabilities for the habits list endpoint:
- Filter by type (BOOLEAN, COUNTER, VALUE)
- Filter by frequency (DAILY, WEEKLY, MONTHLY)
- Filter by archived status
- Text search in habit name and description
- All filters can be combined
- Filters work with pagination
Technical changes:
- Added FilterParams to GetUserHabitsQuery
- Created HabitFilter struct in repository interface
- Implemented dynamic SQL query building in SQLite repository
- Updated HTTP handler to parse filter query parameters
- Added comprehensive tests for repository and handler filtering
- Updated all test mocks with new filter methods
- Create pagination package with Params and Response structs
- Add FindActiveByUserIDWithPagination and CountActiveByUserID methods to HabitRepository interface
- Implement pagination in SQLite repository using LIMIT and OFFSET
- Update GetUserHabitsHandler to support optional pagination parameters
- Modify HTTP endpoint to parse 'page' and 'page_size' query params (default: page=1, page_size=50, max=100)
- Add GetUserHabitsResponse DTO with pagination metadata
- Maintain backward compatibility - endpoint works with and without pagination params
- Add comprehensive tests for pagination logic in repository, handler, and pagination package
- Update all mock repositories to implement new pagination methods
Timezone is now sent from the client on each request that needs it,
instead of storing it in the database. This simplifies the model and
allows timezone to be dynamic (useful for traveling users).
Changes:
- Remove timezone field from User entity
- Remove timezone from user registration
- GET /habits/today now requires ?timezone= query param
- Add migration to drop timezone column from database
- Update related tests
