Project Migration to Go (Golang)

[JohanDevl]

Objective

Migrate the Export_Trakt_4_Letterboxd project from its current state to Go language to improve performance, maintainability, and distribution.

Benefits of Go Migration

1. Performance

   • Faster execution through native compilation
   • Better memory management
   • Excellent concurrent operations performance

2. Distribution

   • Single, self-contained binary
   • No external dependencies required
   • Simpler cross-platform distribution

3. Maintainability

   • Strong static typing
   • Explicit error handling
   • Easier to test
   • Excellent integrated toolchain

Key Migration Points

1. Project Structure

• Reorganize project according to Go conventions
• Implement modular structure
• Use Go modules for dependency management

2. Features to Port

• Trakt API integration
• Letterboxd export functionality
• Configuration management
• Logging system
• Unit and integration tests
• Multilingual support

3. Docker

• Adapt Dockerfile for Go
• Optimize Docker image
• Maintain docker-compose compatibility

4. Documentation

• Update README
• Document API with godoc
• Update installation and contribution guides

Proposed Steps

1. Preparation Phase

   • Create new branch for Go development
   • Set up Go development environment
   • Define new project structure

2. Development Phase

   • Implement core features one by one
   • Port existing tests
   • Develop new tests as needed

3. Testing Phase

   • Performance testing
   • Compatibility testing
   • Integration testing

4. Documentation Phase

   • Update all documentation
   • Create new guides if necessary

5. Deployment Phase

   • Production testing
   • User migration
   • Update deployment scripts

Questions to Consider

• Which minimum Go version to target?
• Which Go libraries to use as replacements for current dependencies?
• How to handle the transition period?
• Should both versions be maintained in parallel for some time?

Next Steps

1. Validate this migration proposal
2. Define detailed timeline
3. Assign responsibilities
4. Start with a simple prototype
