impact-analysis

To map codebase impact, you trace direct and indirect imports, dynamic imports, and re-exports from the modified TypeScript file. This generates an impact map showing downstream consumers and affected tests to guide safe deployments.

Dependency tracing in JavaScript projects maps how modifications ripple through imports and exports. You need it before refactoring or deploying changes to identify downstream consumers, evaluate test coverage impact, and prevent regressions.

Yes, you can assess regression risk by traversing dependencies to find affected tests. It identifies which test files cover the direct and indirect consumers of your target function, allowing you to run targeted tests before deployment.

Static analysis works with dynamic imports and re-exports by explicitly checking for them during dependency traversal. It maps these indirect usage patterns alongside direct exports to produce a comprehensive impact map for your changes.

You need to provide the target file path and an optional function name. The analysis then traverses your codebase dependencies, evaluates test coverage, and outputs actionable guidance with recommended tests for your changes.
