SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Analyzes the impact of changing a file or function to reveal what else would break and helps plan safe deployments.

Core Features & Use Cases

Direct and indirect dependency discovery across the codebase.
Tests impact assessment and regression risk mapping.
Automatic generation of an impact map to guide targeted changes.

Quick Start

Provide the target file path (and an optional function name) to generate an impact map and recommended tests.

FAQPage Schema

How do I map the impact of changing a TypeScript file on my codebase?▼

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.

What is dependency tracing for JavaScript projects and when do I need it?▼

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.

Can I assess regression risk by identifying affected tests before changing a function?▼

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.

Does static analysis work with dynamic imports and re-exports in a codebase?▼

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.

What do I need to provide to generate an impact map for my code?▼

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.
