SmartFuzzy Improvement Plan

Current Status

• ESM imports/exports fixed with .js extensions
• Basic fuzzy matching functionality works
• Tests run individually with tsx but fail with pnpm test
• Using older versions of dependencies

Improvement Plan

1. Fix Testing Infrastructure

1.1 Fix Test Runner Configuration

• Investigate why pnpm test fails while individual tests run with tsx succeed
• Check if tsrun command is properly installed and available (current error shows "tsrun: command not found")
• Examine the tstest configuration in package.json and update if needed
• Verify that @git.zone/tstest dependency is properly installed and configured
• Consider updating the test script to use tsx directly if tstest continues to be problematic

1.2 Update Test Syntax and Standards

• Convert all tests from chai-style syntax (expect().to.be) to SmartExpect syntax (expect().toBeInstanceOf())
• Implement consistent test structure across all test files
• Add proper setup and teardown patterns where needed
• Replace console.log statements with proper assertions to validate results
• Add descriptive error messages to assertions to improve test debugging

1.3 Expand Test Coverage

• Add tests for empty dictionaries and edge cases
• Test with extremely large dictionaries to verify performance
• Add tests for unicode/special character handling
• Test with very similar strings to validate fuzzy matching accuracy
• Add tests for error conditions and input validation
• Implement tests for all public APIs and features

1.4 Test Automation and CI

• Add test coverage reporting
• Set up continuous integration for automated testing
• Add performance regression tests
• Create test fixtures for consistent test data
• Add browser-based tests for web compatibility

2. Code Quality Improvements

• Add proper TypeScript documentation comments to all public methods
• Implement consistent error handling
• Add input validation for all public methods
• Standardize method naming conventions (e.g., get* vs find*)

3. Feature Enhancements

• Add configurable threshold options for matching
• Implement stemming/lemmatization support for better text matching
• Add language-specific matching options
• Support for weighted matching across multiple fields
• Add batch processing capabilities for large datasets

4. Performance Optimizations

• Implement caching for repeated searches
• Optimize indexing for large dictionaries
• Add benchmarking tests to measure performance improvements

5. Dependencies and Build System

• Update to latest versions of dependencies
• Ensure proper tree-shaking for browser bundle
• Add browser-specific build configuration
• Implement proper ES module / CommonJS dual package setup

6. Documentation

• Create comprehensive API documentation
• Add usage examples for common scenarios
• Create benchmarks comparing to other fuzzy matching libraries
• Document performance characteristics and optimization strategies

7. Developer Experience

• Add VS Code debugging configuration
• Implement changelog generation
• Set up automated release process
• Add contribution guidelines
