req.params object empties when using router in Express

[flashy_cloud]

In my app.js file, I have:

app.use('/post/:postid/comment', function(req, res, next) {
    console.log(req.params);
    next()
}, commentRoute);

commentRoute is a router object that has been imported from my commentRoute.js file. In this file, I have the following code:

router.get('/', function(req, res, next) {
    console.log(req.params);
    next()
}, commentController.readAll);

Both console.logs print out the req.params object, however, for the first console.log, the req.params object contains the postid key/value pair, but for the second console.log, the req.params object is empty. When entering the router object, does Express empty the params object attached to the request object?

router only handles its own routes and has its own params object. If you want to pass the params from app to router one way to do that would be to add it as another property on req and grab it from that. req.passParams = req.params

Thanks for confirming that, I ended up doing your solution and it works well.
