Adding middleware after swagger middleware, not seeing req.swagger

[garrettsutula]

Opening this to get a little guidance on adding middleware that can access req.swagger after it's added by the swagger metadata middleware. I have the following code for initializing the middleware:

SwaggerExpress.create(config, function(err, swaggerExpress) {
  if (err) { throw err; }

  // install middleware
  swaggerExpress.register(app);

  app.use(function(req, res, next){
    console.log(req.swagger);
  });

  var port = process.env.PORT || 10010;
  app.listen(port);

  if (swaggerExpress.runner.swagger.paths['/hello']) {
    console.log('try this:\ncurl http://127.0.0.1:' + port + '/hello?name=Scott');
  }
});

but req.swagger is undefined when that middleware runs.

If I follow the pattern in the docs, I still have the same problem which is demonstrated in this repo

Since this isn't a bug, I'm closing but we can continue talking.

Thanks for the quick response & fair point on closing it. :)

I loaded up debug and I'm honestly not sure why it's not working. It seems like middleware is associated in the correct order, after swaggerMetadata:

Make a request and see if swagger-tools:middleware:metadata finds a matching route for the request.
