Issues with req.params not getting invoked in Express.js

Question

Issues with req.params not getting invoked in Express.js

After hours of contemplation, I'm still struggling to figure out the issue at hand.

Let's start with how I defined a route:

var home = require('./routes/home');
var app = express();

app.use('/home/:client', home);

The code in my home.js file is as follows:

var express = require('express');
var router = express.Router();

router.get('/', function(req, res, next) {
    res.render('homeview', { title: 'Welcome',
                             user: username});
});

router.get('/:client', function(req, res, next) {
    var theClient = req.params.client;
    console.log(theClient)
});

module.exports = router;

Now, when I attempt to visit this URL:

Nothing seems to happen. It never reaches the second router.get and fails to log anything. Can anyone spot the issue here?

Check out the solution on this GitHub repository.

In your app.js file:

const express = require('express');
const app = express();
const port = process.env.PORT || 3000;
const homeRouter = require('./home');

app.use('/home', homeRouter);

app.route('/')
    .all(function (request, response, next) {
        // Perform necessary actions
        next();
    })
    .get(function (request, response, next) {
        response.send('OK GET - Hello Stack Overflow');
        next();
    });

app.listen(port, function (error) {
    if (error) {
        console.error(error.message);
    } else {
        console.info('Server up and running. Listening on port ' + port);
    }
})

In your home.js file:

const express = require('express');
const homeRouter = express.Router();

const router = (function (router) {

    // Define the home page route
    router.get('/', function (req, res) {
        res.send('home route - homepage');
    });
    // Define the about route
    router.get('/:client', function (req, res) {
        res.send(req.params.client);
    });

    return homeRouter;
})(homeRouter);

module.exports = router;
