Route Map

Mixed audience · Application routes and API endpoints with context

A complete listing of user-facing pages and backend API endpoints. This map shows every URL a user or client can interact with, along with the source file that handles each route.

Route Detection

This project is a CLI tool — it does not expose HTTP routes or serve web pages. This is expected behavior, not a detection failure.

CLI tools interact through terminal commands rather than URLs. See the System Overview or Developer Onboarding documents for command documentation.

![Docs by RepoLens](https://github.com/CHAPIBUNNY/repolens) · Examples

API Surface

Engineers · Backend API endpoints with usage examples

This page documents both the API endpoints the application exposes and the external services it integrates with. Use it as a reference for understanding the system's interfaces.

Internal API Endpoints

These are the backend services the application provides to handle incoming requests.

No API routes were detected in this scan. If your project uses a routing framework (Express, Fastify, NestJS, etc.), ensure the relevant directories are included in your scan.include patterns.

External API Integrations

Third-party services the application connects to, grouped by category.

No external API integrations were detected. This section populates automatically when RepoLens identifies SDK imports or API client usage in your codebase.

HTTP method reference — GET: retrieve data, POST: create, PUT/PATCH: update, DELETE: remove.

Security Hotspots

Engineers · Security anti-pattern detection with CWE classification

No security anti-patterns were detected in the scanned source files.

RepoLens scans JavaScript and TypeScript source files for common security risks including code injection (eval), XSS (innerHTML), SQL injection, command injection, prototype pollution, hardcoded credentials, and insecure randomness.

Test files, configs, and build outputs are excluded from analysis to reduce false positives.

Scoring Methodology

The health score (0–100) is computed from four dimensions:

Factor	Weight	How It's Measured
Complexity	–1/pt above 10, –2/pt above 30	Cyclomatic complexity for JavaScript/TypeScript, Python, and Go (regex, not AST)
Function complexity	–2/pt above 8 per function	Highest complexity function in the file
Coupling	–1/5 units above 20	Fan-in × Fan-out (import connections)
Documentation	–10 if <50%, –5 if <80%	JSDoc/TSDoc coverage of exports
Security	–10/high, –5/medium finding	Security anti-pattern findings in file

Generated by RepoLens code health analysis. Complexity covers JavaScript/TypeScript, Python, and Go. It is regex-based and may differ from AST-based tools. Scores are relative indicators, not absolute quality measures.
