# Bit CLI Improvement Roadmap

## Phase 1: Core Utilities and Standardization (High Impact/Low Effort)
Target: 1-2 days implementation
- [ ] Create utils/docker.js
  - Centralize container operations
  - Add health checks
  - Standardize exec operations
  ```javascript
  export const docker = {
    getContainerId: (service) => {},
    execInContainer: (container, cmd) => {},
    checkHealth: (service) => {}
  }
  ```

- [ ] Implement utils/config.js
  - Move hardcoded paths to config
  - Define service names
  - Set default timeouts
  ```javascript
  export const config = {
    paths: { web: './apps/web', pb: './apps/pb' },
    services: { web: 'web', pb: 'pb' },
    timeouts: { startup: 3000, sync: 1000 }
  }
  ```

## Phase 2: Error Handling and Logging (High Impact/Medium Effort)
Target: 2-3 days implementation
- [ ] Enhance utils/errors.js
  - Create error classes for different scenarios
  - Add error codes
  - Implement recovery suggestions
  ```javascript
  export class DockerError extends Error {}
  export class ConfigError extends Error {}
  export class NetworkError extends Error {}
  ```

- [ ] Create utils/logger.js
  - Unified logging interface
  - Consistent styling
  - Progress tracking
  ```javascript
  export const logger = {
    info: (msg) => {},
    error: (err) => {},
    progress: (task) => {}
  }
  ```

## Phase 3: Command Structure Refactoring (Medium Impact/Medium Effort)
Target: 2-3 days implementation
- [ ] Implement Command Factory Pattern
  ```javascript
  class BitCommand {
    constructor(program) {
      this.program = program;
    }
    register() {}
    execute() {}
  }
  ```

- [ ] Standardize Command Registration
  - Consistent parameter handling
  - Unified help documentation
  - Standard lifecycle hooks

## Phase 4: Process and Security Management (Medium Impact/High Effort)
Target: 3-4 days implementation
- [ ] Create Process Manager
  - Handle signals gracefully
  - Manage cleanup operations
  - Track child processes
  ```javascript
  export class ProcessManager {
    registerProcess(proc) {}
    cleanup() {}
    handleSignals() {}
  }
  ```

- [ ] Enhance Security Module
  - Add security middleware
  - Implement permission checks
  - Add audit logging

## Phase 5: Template and Project Structure (Low Impact/High Effort)
Target: 4-5 days implementation
- [ ] Reorganize Templates
  ```
  templates/
    ├── web/
    │   ├── base/
    │   └── extensions/
    ├── pb/
    │   ├── base/
    │   └── plugins/
    └── shared/
        ├── docker/
        └── config/
  ```

- [ ] Implement Template Manager
  - Version control for templates
  - Custom template support
  - Template validation

## Notes and Considerations
1. Each phase can be implemented independently
2. Backward compatibility should be maintained
3. Add tests for new utilities before refactoring existing code
4. Document API changes and new features
5. Consider adding integration tests between phases

## Testing Strategy
Target: Parallel implementation with each phase

### Phase 1: Core Unit Tests
- [ ] Setup Testing Framework
  ```javascript
  // Using Vitest for speed and Bun compatibility
  {
    "scripts": {
      "test": "vitest",
      "test:watch": "vitest watch",
      "test:coverage": "vitest run --coverage"
    }
  }
  ```

- [ ] Docker Utility Tests
  ```javascript
  describe('docker utils', () => {
    test('getContainerId returns correct ID', async () => {})
    test('execInContainer handles errors', async () => {})
    test('checkHealth returns correct status', async () => {})
  })
  ```

- [ ] Configuration Tests
  ```javascript
  describe('config', () => {
    test('loads correct paths', () => {})
    test('validates service names', () => {})
    test('handles environment overrides', () => {})
  })
  ```

### Phase 2: Error and Logging Tests
- [ ] Error Handler Tests
  ```javascript
  describe('error handling', () => {
    test('DockerError includes recovery steps', () => {})
    test('ConfigError provides clear messages', () => {})
    test('handles nested errors correctly', () => {})
  })
  ```

- [ ] Logger Tests
  ```javascript
  describe('logger', () => {
    test('formats messages consistently', () => {})
    test('handles different log levels', () => {})
    test('manages spinner states', () => {})
  })
  ```

### Phase 3: Command Tests
- [ ] Command Factory Tests
  ```javascript
  describe('BitCommand', () => {
    test('registers commands correctly', () => {})
    test('handles command options', () => {})
    test('validates input parameters', () => {})
  })
  ```

- [ ] Integration Tests for Commands
  ```javascript
  describe('command integration', () => {
    test('start command initializes services', async () => {})
    test('stop command cleans up resources', async () => {})
  })
  ```

### Phase 4: Process and Security Tests
- [ ] Process Manager Tests
  ```javascript
  describe('ProcessManager', () => {
    test('handles SIGTERM gracefully', () => {})
    test('cleans up child processes', () => {})
    test('manages concurrent processes', () => {})
  })
  ```

- [ ] Security Tests
  ```javascript
  describe('security', () => {
    test('validates permissions correctly', () => {})
    test('prevents unauthorized access', () => {})
    test('logs security events', () => {})
  })
  ```

### Phase 5: Template Tests
- [ ] Template Validation Tests
  ```javascript
  describe('templates', () => {
    test('validates template structure', () => {})
    test('handles custom templates', () => {})
    test('manages template versions', () => {})
  })
  ```

### E2E Testing Strategy
- [ ] Setup E2E Framework
  ```javascript
  // Using Playwright for E2E testing
  {
    "scripts": {
      "test:e2e": "playwright test",
      "test:e2e:ui": "playwright test --ui"
    }
  }
  ```

- [ ] Critical Path Tests
  ```javascript
  test('complete project creation flow', async () => {
    // Test full project creation and startup
  })
  ```

- [ ] Container Integration Tests
  ```javascript
  test('container synchronization', async () => {
    // Test package installation and sync
  })
  ```

### CI/CD Integration
- [ ] GitHub Actions Workflow
  ```yaml
  name: Test Suite
  on: [push, pull_request]
  jobs:
    test:
      runs-on: ubuntu-latest
      steps:
        - uses: actions/checkout@v3
        - uses: oven-sh/setup-bun@v1
        - run: bun install
        - run: bun test
        - run: bun test:e2e
  ```

### Test Coverage Goals
- Unit Tests: 85%+ coverage
- Integration Tests: Key workflows covered
- E2E Tests: Critical user paths
- Performance Tests: Response times and resource usage

### Testing Guidelines
1. Write tests before implementing features
2. Mock external services (Docker, filesystem)
3. Use fixtures for template testing
4. Include performance benchmarks
5. Regular test maintenance and updates

## Future Considerations
- Container orchestration improvements
- Plugin system for extensibility
- Development environment parity checks
- Performance monitoring and optimization
- Cross-platform testing and compatibility

## Implementation Guidelines
1. Create feature branches for each phase
2. Write tests before implementation
3. Update documentation with changes
4. Create migration guides if needed
5. Regular check-ins and reviews
