[aalamu]

Description

This pull request includes significant refactoring and enhancements to improve the handling of events, streams, and live broadcasts within the application. Key changes involve updates to controllers, services, DTOs, and response classes, as well as the addition of new route mappings and localization updates. These modifications aim to streamline code structure, improve functionality, and enhance the overall user experience.

Summary of Changes

1. Addition of .gitignore for Sensitive Files

• Added a .gitignore file to exclude script files containing sensitive information for various environments (development, staging, production).

2. Localization Updates

• Added localization message keys to CreateStreamResponse.
• Updated localization files (messages_en_US.properties and messages_fr.properties) with new message keys for better internationalization support.

3. Controller and Route Mapping Updates

• Moved rescheduleEvent() method from EventController to UserEventController for better routing logic.
• Added LiveBroadcastController with route mappings to facilitate actions through the Live Broadcast API.
• Introduced UserLiveBroadcastController to allow users to manage and interact with their created broadcasts or live streams.

4. DTO and Response Class Renaming

• Renamed DTOs for clarity and to reduce redundancy:
  • UpdateEventVisibilityDto.java to UpdateEventOrStreamVisibilityDto.
  • ProcessAttendeeRequestToJoinEventDto.java to ProcessAttendeeRequestToJoinEventOrStreamDto.
• Added new response classes:
  • DeletedStreamResponse for handling stream deletions.
  • NotAttendingStreamResponse for users opting not to attend events.
  • ProcessAttendeeRequestToJoinStreamResponse and UpdateStreamVisibilityResponse.

5. Service Layer Enhancements

• Refactored EventServiceImpl to improve code organization, modularity, and maintainability.
• Updated LiveBroadcastService and LiveBroadcastServiceImpl with new interface methods and initial skeleton implementations to be developed further.
• Refactored YouTubeChannelService and YouTubeLiveBroadcastService to address bugs and improve service functionality.
• Added static methods in YouTubeVideoPart to enable easier reuse of constants across services.

6. New Methods and Functionalities

• Added StreamAttendee.setIsNotAttending() method, allowing users to indicate their decision not to attend a previously joined event or stream.

7. Documentation Improvements

• Added comprehensive documentation to new and updated methods to ensure clarity and facilitate easier maintenance.

Testing

• Ensured that all new and modified functionalities were tested to verify correctness.
• Conducted localization tests to confirm message keys are correctly applied in CreateStreamResponse and other relevant classes.

Next Steps

• Complete the implementation of skeleton methods in LiveBroadcastServiceImpl.
• Further testing and validation of the refactored services and controllers.
• Address any feedback or issues identified during the code review process.
