title: Framework Routes
description: CodeGraph links URL patterns to the handlers that serve them.
---

CodeGraph detects web-framework routing files and emits `route` nodes linked by `references` edges to their handler classes or functions. Querying the callers of a view or controller then surfaces the URL pattern that binds it.

| Framework | Shapes recognized |
|---|---|
| **Django** | `path()`, `re_path()`, `url()`, `include()` in `urls.py` (CBV `.as_view()`, dotted paths) |
| **Flask** | `@app.route('/path', methods=[...])`, blueprint routes |
| **FastAPI** | `@app.get(...)`, `@router.post(...)`, all standard methods |
| **Express** | `app.get(...)`, `router.post(...)` with middleware chains |
| **NestJS** | `@Controller` + `@Get/@Post/...`, GraphQL `@Resolver` + `@Query/@Mutation`, `@MessagePattern`/`@EventPattern`, `@SubscribeMessage` |
| **Laravel** | `Route::get()`, `Route::resource()`, `Controller@action`, tuple syntax |
| **Drupal** | `*.routing.yml` routes (`_controller`, `_form`, entity handlers); `hook_*` implementations in `.module`/`.theme`/`.install`/`.inc` |
| **Rails** | `get '/x', to: 'users#index'`, hash-rocket `=>` syntax |
| **Spring** | `@GetMapping`, `@PostMapping`, `@RequestMapping` on methods |
| **Play** | `GET`/`POST`/… verb routes in `conf/routes` → `Controller.method` actions (Scala + Java) |
| **Gin / chi / gorilla / mux** | `r.GET(...)`, `router.HandleFunc(...)` |
| **Axum / actix / Rocket** | `.route("/x", get(handler))` |
| **ASP.NET** | `[HttpGet("/x")]` attributes on action methods |
| **Vapor** | `app.get("x", use: handler)` |
| **React Router** / **SvelteKit** | Route component nodes |
| **Vue Router** / **Nuxt** | `pages/` file-based routes, `server/api/` endpoints, route middleware |
| **Astro** | `src/pages/` file-based routes (`.astro` pages + `.ts` endpoints, `[param]`/`[...rest]` syntax) |

Route resolution is automatic — there's nothing to configure. If a framework file is recognized, its routes appear in the graph after the next index or sync.
