From de868d50811bc26fe094e457ec445523ace480f1 Mon Sep 17 00:00:00 2001 From: DaxServer Date: Wed, 27 Aug 2025 11:38:56 +0200 Subject: [PATCH] feat(dependency-traversal): Implement comprehensive type dependency traversal This commit introduces a comprehensive type dependency traversal implementation that combines AST traversal, dependency collection, and analysis. The key changes are: - Implement `DependencyTraversal` class that manages the dependency graph using Graphology library - Add methods to extract interface and type alias references from type declarations - Introduce `TypeReferenceExtractor` interface to allow customization of type reference extraction - Implement `ProcessingOrderResult` to analyze the optimal processing order for interfaces and type aliases These changes enable efficient management of type dependencies, which is crucial for generating code that respects the correct order of type declarations. ---
