express-capture-route

Capture route definitions, and reconstruct the original route.

Wrap your Router and express() calls in capture, and it will annotate the objects such that it can recover the original path, through multiple layers of router and mounted sub-apps.

Example

See also examples/readme.ts: npm run example

import * as express from 'express';
import { capture, recoverFromHandler, recoverFromRequest } from 'express-capture-route';
const router = capture(express.Router());
router.get('/foo/:bar', foo);

const app = express();
app.use(someMiddleWare);
capture(app).use('/api', router);

recoverFromHandler(foo).path === ['/api', '/foo/:bar'];

// or, with some `onFinished` middleware
app.use((req, res, next) => {
  next();
  recoverFromRequest(req).path;
});
