• TypeScript/JavaScript language support (Epic 20): Full parsing for .ts, .tsx, .js, .jsx files using tree-sitter-typescript and tree-sitter-javascript. Single TypeScriptParser class handles all 4 file types with 3 grammar variants (typescript, tsx, javascript).
  • Symbol extraction: classes, functions, methods, interfaces, enums, type aliases, const/let/var declarations, arrow functions, getter/setters, abstract classes, generics
  • Import/export extraction: ES module imports (named, default, namespace, side-effect), CommonJS require(), type-only imports, re-exports, barrel exports
  • Inheritance extraction: class extends, implements, interface extends (single and multiple)
  • Call extraction: function calls, method calls, static calls, constructor calls (new), chained calls
  • TS-specific features: decorators, React JSX/TSX components, namespaces, ambient declarations (.d.ts)
  • 77 new tests (68 unit + 9 integration), all passing
• New optional dependency group: pip install ai-codeindex[typescript] installs tree-sitter-typescript and tree-sitter-javascript
• Scanner support: typescript and javascript in LANGUAGE_EXTENSIONS and .codeindex.yaml config
• CLI integration: codeindex parse file.ts produces JSON output with full symbol/import/call data
