code_route

code_route resolves an HTTP route path to the controller method that handles it. It parses framework decorators (NestJS, Express, Fastify) and returns the handler’s file and line number.

Usage

code_route(route="/api/users")
code_route(route="/api/orders", method="POST")
code_route()

Parameters

Parameter	Type	Default	Description
route	string	—	URL path to find a handler for
method	"GET" | "POST" | "PUT" | "DELETE" | "PATCH"	—	HTTP method filter

Output

GET /api/users → UserController.list
  src/controllers/user.ts:24

POST /api/users → UserController.create
  src/controllers/user.ts:51

Calling code_route() with no arguments lists all registered routes.

When to use

• Trace a failing API request to its handler
• Find which function to read when debugging a specific endpoint
• Get a full route inventory for documentation or security review
