# JsonFieldExplorer (jfe) - Development Roadmap

## Phase 1: Core UX Improvements (High Impact, Low Effort)

_Target: Next 2-4 weeks_

### Better CLI Interface

- [ ] Add proper argument parsing with commander.js or yargs
- [ ] Support `--help` flag with comprehensive usage information
- [ ] Support `--version` flag
- [ ] Add `--format` flag for output format selection
- [ ] Support multiple file inputs
- [x] Add `--quiet` mode for minimal output
- [ ] Add `--verbose` mode for detailed analysis
- [ ] Add `--output` flag to write results to file

### Enhanced Output Formatting

- [ ] Add color-coded output using chalk for better readability
- [ ] Implement `--json` flag for JSON output format
- [ ] Add table format option using cli-table3
- [ ] Create tree view for nested structures
- [ ] Add option to sort paths (alphabetically, by depth, by type)
- [ ] Add `--no-color` option for CI/scripting environments

### Error Handling & User Experience

- [ ] Improve error messages with actionable suggestions
- [ ] Add JSON validation before processing
- [ ] Add progress indicators for large files (>10MB)
- [ ] Add memory usage warnings for huge files (>100MB)
- [ ] Handle and report malformed JSON gracefully
- [ ] Add file existence validation

## Phase 2: Advanced Analysis Features (Medium Impact, Medium Effort)

_Target: Next 1-2 months_

### Statistical Analysis

- [ ] Implement value frequency analysis for all fields
- [ ] Add min/max/average calculations for numeric fields
- [ ] Add string length statistics (min/max/average)
- [ ] Implement enum detection with configurable thresholds
- [ ] Add unique value counts per field
- [ ] Show null/undefined value percentages
- [ ] Add `--stats` flag to enable detailed statistics

### Pattern Recognition

- [ ] Detect common patterns: emails, URLs, dates, UUIDs
- [ ] Add phone number pattern detection
- [ ] Implement JSON schema inference capabilities
- [x] Analyze array consistency (same structure across elements)
- [x] Detect missing fields across array elements (optional field detection)
- [ ] Add custom pattern detection via regex

### Filtering & Querying

- [ ] Add `--type` filter (e.g., `--type string,number`)
- [ ] Add `--depth` filter to limit analysis depth
- [ ] Add `--field` search for specific field names
- [ ] Add `--exclude` pattern matching for paths
- [ ] Add `--include` pattern matching for paths
- [ ] Support JSONPath-style queries

## Phase 3: Integration & Ecosystem (High Impact, High Effort)

_Target: Next 3-6 months_

### Multiple Format Support

- [ ] Add YAML input support
- [ ] Implement CSV output format
- [ ] Add Markdown table output format
- [ ] Create HTML report generation
- [ ] Add XML input support
- [ ] Support TOML input format

### Developer Integrations

- [ ] Generate JSON Schema from analyzed structure
- [ ] Generate TypeScript interfaces
- [ ] Generate OpenAPI/Swagger schema definitions
- [ ] Create VSCode extension
- [ ] Add Vim plugin support
- [ ] Create programmatic API for Node.js integration

### Performance & Scalability

- [ ] Implement streaming parser for large files (>1GB)
- [ ] Add parallel processing for multiple files
- [ ] Optimize memory usage for deep nesting
- [ ] Add resume capability for interrupted analysis
- [ ] Implement file chunking for very large datasets
- [ ] Add caching for repeated analysis

## Phase 4: Advanced Features (Nice to Have)

_Target: 6+ months_

### Comparison Tools

- [ ] Compare JSON structures between two files
- [ ] Implement diff mode showing structural changes
- [ ] Add merge analysis for multiple similar files
- [ ] Create compatibility analysis between schemas
- [ ] Track schema evolution over time

### Interactive Features

- [ ] Build interactive web UI
- [ ] Add real-time analysis in watch mode
- [ ] Create query language for complex filtering
- [ ] Implement live reload for file changes
- [ ] Add interactive field exploration

### Reporting & Documentation

- [ ] Generate comprehensive PDF/HTML reports
- [ ] Export to documentation formats (GitBook, etc.)
- [ ] Integration with documentation generators
- [ ] Create shareable analysis URLs
- [ ] Add report templates

## Technical Debt & Maintenance

### Code Quality

- [ ] Add TypeScript definitions
- [ ] Increase test coverage to >90%
- [ ] Add integration tests
- [ ] Set up GitHub Actions CI/CD
- [ ] Add automated security scanning
- [ ] Implement code linting and formatting

### Documentation

- [ ] Write comprehensive API documentation
- [ ] Create usage examples for all features
- [ ] Add contributing guidelines
- [ ] Create troubleshooting guide
- [ ] Add performance benchmarks

### Dependencies & Architecture

- [ ] Evaluate and update dependencies regularly
- [ ] Implement plugin system for extensibility
- [ ] Add configuration file support (.jferc)
- [ ] Separate concerns: parsing, analysis, formatting, output
- [ ] Create modular architecture for easy testing

## Community & Ecosystem

### Package Management

- [ ] Publish to npm with proper versioning
- [ ] Create Homebrew formula for macOS
- [ ] Add to popular package managers (apt, yum, etc.)
- [ ] Create Docker image
- [ ] Add to Chocolatey for Windows

### Community Building

- [ ] Create comprehensive README with examples
