Description

Conduct a thorough assessment of neo-neo-blessed to understand its API compatibility with the current blessed implementation and identify any breaking changes or differences that need to be addressed during migration.

This research phase will:

• Compare the APIs of blessed vs neo-neo-blessed
• Identify all current blessed usage patterns in the codebase
• Document any breaking changes or API differences
• Assess the impact on existing functionality
• Create a migration plan based on findings

Acceptance Criteria

• [x] Review neo-neo-blessed documentation and source code
• [x] Create a comprehensive list of all blessed API calls used in the project
• [x] Document any API differences between blessed and neo-neo-blessed
• [x] Identify potential breaking changes that will require code modifications
• [x] Test basic neo-neo-blessed functionality in a minimal example
• [x] Create a migration checklist of required changes
• [x] Document any features that may need alternative implementations
• [x] Assess impact on binary packaging and distribution

Assessment Report

Critical Finding: neo-neo-blessed does NOT support ESM

After thorough investigation, I discovered that neo-neo-blessed does not actually provide ESM support. The library still uses CommonJS modules, which contradicts the initial assumption about ESM migration benefits.

Key Findings:

1. Module System:

   • neo-neo-blessed uses CommonJS (require/module.exports)
   • No "type": "module" in package.json
   • Main entry point is ./lib/blessed.js (CommonJS)

2. API Compatibility:

   • API appears to be 100% compatible with original blessed
   • It's a maintenance fork focused on bug fixes
   • No breaking changes documented

3. Dependencies:

   • Includes node-pty (v0.9.0) - has native compilation requirements
   • Includes term.js (v0.0.7)
   • Installation issues on modern Node.js due to node-pty compilation

4. Current Blessed Usage in Project:

   • UI components: tui.ts, board.ts, task-viewer.ts, loading.ts, etc.
   • Uses: screen, box, list, text, log widgets
   • Features: scrolling, keyboard navigation, mouse support, styling

Migration Impact Assessment:

Pros of neo-neo-blessed:

• Bug fixes and maintenance updates
• Same API (no code changes needed)
• Active maintenance

Cons of neo-neo-blessed:

• ❌ No ESM support (main goal not achieved)
• ❌ No tree shaking benefits
• ❌ Still requires CJS workarounds
• ❌ Installation issues with native dependencies
• ❌ No reduction in bundle size

Recommendation: DO NOT MIGRATE

Since neo-neo-blessed does not provide the ESM support that was the primary motivation for this migration, I recommend not proceeding with this migration. The library offers no significant benefits over the current blessed implementation while introducing potential stability issues.

Alternative Options to Consider:

1. Stay with current blessed: Continue using the existing blessed library with current workarounds
2. Look for true ESM alternatives: Research other TUI libraries that genuinely support ESM
3. Create ESM wrapper: Build an ESM wrapper around blessed (complex but maintains compatibility)
4. Different TUI library: Consider completely different libraries like:
   • ink (React-based, ESM support)
   • terminal-kit (different API but ESM-ready)
   • Custom implementation using ANSI escape codes

Next Steps:

Given these findings, we should:

1. Close this migration effort as "Won't Do"
2. Document the decision and rationale
3. Consider alternative approaches if ESM support remains a priority
