When does this happen?

IF A frontend JavaScript/TypeScript file makes a fetch/axios call to an API endpoint, and the backend route is defined in a different language (e.g., Python FastAPI, Express).

How others solved it

THEN Detect cross-language edges by matching REST API calls to route definitions across languages. Include these edges in impact analysis and security scanning so that deleting a backend route also shows the frontend callers as broken.

Depwire matches `fetch('/api/users')` in TypeScript to `@app.get('/api/users')` in Python and treats them as a dependency edge.
