🧠 Advanced Code Analysis Engine

Code-y's power stems from its sophisticated code analysis engine, which performs a deep dive into your JavaScript, TypeScript, and React projects.

Deep AST (Abstract Syntax Tree) Parsing

Code-y meticulously parses your source code to build a comprehensive understanding of its structure and components.

  • Multi-language Support: Full analysis capabilities for TypeScript (`.ts`, `.tsx`) and JavaScript (`.js`, `.jsx`), including modern ECMAScript features.
  • Nested Code Extraction: Accurately discovers and analyzes functions defined within other functions, methods within classes, and complex nested React component hierarchies.
  • Comprehensive Entity Recognition: Automatically identifies and categorizes a wide range of code entities:
    • React Components (both functional and class-based)
    • Standard functions and arrow functions
    • Classes, including their methods, constructors, and properties
    • Interfaces and type aliases (for TypeScript)
    • Constants (`const`) and variables (`let`, `var`)
    • Custom React hooks (functions following the `use` prefix convention)

Comprehensive Relationship Mapping

Understanding how different parts of your codebase connect is crucial. Code-y excels at mapping these relationships:

  • Import/Export Analysis: Tracks all `import` and `export` statements to map module dependencies and understand how code is shared and utilized across files.
  • Component Usage Detection: Identifies precisely where React components are rendered within JSX, providing a clear view of your UI structure.
  • Method Call Tracking: Maps function and method invocations across your entire project, helping you trace data flow and understand operational logic.
  • Inheritance Relationships: For object-oriented code, Code-y detects class extensions (`extends`) and interface implementations (`implements`).
  • Circular Dependency Detection: Automatically identifies and flags circular import patterns, which can lead to runtime issues and difficult-to-debug errors.
  • Prop Drilling Analysis: Detects instances where props are passed down through multiple layers of components unnecessarily, suggesting potential areas for refactoring using context or state management.

Intelligent Duplicate Detection

Code-y employs multi-level similarity analysis to help you identify and manage code duplication:

  • Exact Duplicates: Finds code blocks that are 100% identical.
  • Near Duplicates: Identifies code with very high similarity (e.g., 95%+) that may differ only by minor changes like variable names or comments.
  • Structural Similarity: Detects code segments that share the same underlying logic or structure, even if variable names or specific values differ.
  • Pattern-based Similarity: Aims to identify similar algorithms or common programming patterns used in different parts of the code.
  • Smart Deduplication: When duplicates are found, Code-y can intelligently consolidate these entities in the documentation while still preserving information about all original file locations.
  • Similarity Scoring: Utilizes a combination of algorithms for robust similarity assessment, including hash-based comparisons, token-based Jaccard similarity, AST structure comparison, and analysis of code length and complexity.
