Routing of express-subdomain

Question

I'm using express-subdomain .

The router that handles requests through a subdomain is the same as the router that handles requests without a subdomain.

I know that my 'app.js' setting is wrong. How can I solve this problem? I want to know a good way. like this:

app.use(subdomain('banana', ('/about', bananaRouter);

and If this is an easy question, please forgive me. I couldn't find any of the same problems in my country. I'm sorry.

// /app.js
const appleRouter = require('./routes/apple/index');
const appleAboutRouter = require('./routes/apple/about');
const applePriceRouter = require('./routes/apple/price');

const bananaRouter = require('./routes/banana/index');
const bananaAboutRouter = require('./routes/banana/about');
const bananaPriceRouter = require('./routes/banana/price');

const grapeRouter = require('./routes/grape/index');
const grapeAboutRouter = require('./routes/grape/about');
const grapePriceRouter = require('./routes/grape/price');

app.use(subdomain('banana', bananaRouter));
app.use(subdomain('grape', grapeRouter));

app.use('/', appleRouter);
app.use('/about', appleAboutRouter);
app.use('/price', applePriceRouter);

app.use('/', bananaRouter);
app.use('/about', bananaAboutRouter);
app.use('/price', bananaPriceRouter);

app.use('/', grapeRouter);
app.use('/about', grapeAboutRouter);
app.use('/price', grapePriceRouter);

// /routes/apple/index
const express = require('express');
const router = express.Router();

router.get('/', function (req, res, next) {
    res.send('I am Apple');
});
module.exports = router;

// /routes/apple/about
const express = require('express');
const router = express.Router();

router.get('/view', function (req, res, next) {
    res.send("Apples don't taste good.");
});
module.exports = router;

// /routes/apple/price
const express = require('express');
const router = express.Router();

router.get('/view', function (req, res, next) {
    res.send("$ 1");
});
module.exports = router;

// /routes/banana/index
const express = require('express');
const router = express.Router();

router.get('/', function (req, res, next) {
    res.send('I am Banana');
});
module.exports = router;

// /routes/banana/about
const express = require('express');
const router = express.Router();

router.get('/view', function (req, res, next) {
    res.send("Bananas are delicious.");
});
module.exports = router;

// /routes/banana/price
const express = require('express');
const router = express.Router();

router.get('/view', function (req, res, next) {
    res.send("$ 2");
});
module.exports = router;

// /routes/grape/index
const express = require('express');
const router = express.Router();

router.get('/', function (req, res, next) {
    res.send('I am Grape');
});
module.exports = router;

// /routes/grape/about
const express = require('express');
const router = express.Router();

router.get('/view', function (req, res, next) {
    res.send("Grapes are purple.");
});
module.exports = router;

// /routes/grape/price
const express = require('express');
const router = express.Router();

router.get('/view', function (req, res, next) {
    res.send("$ 3");
});
module.exports = router;

Expected Behaviour 2:

// http://localhost.com:3000/
I am Apple
// http://localhost.com:3000/about/view
Apples don't taste good.
// http://localhost.com:3000/price/view
$ 1

// http://banana.localhost.com:3000/
I am Banana
// http://banana.localhost.com:3000/about/view
Apples don't taste good. ** not Bananas are delicious. **
// http://banana.localhost.com:3000/price/view
'$ 1' ** not '$ 2' **

Answer 1

I created code sample which resolve you problem :D Firstly you need to add a couple lines to your /etc/hosts file. Example

127.0.0.1 banana.myapp.dev
127.0.0.1 myapp.dev

And after that try to run this script which I wrote for you:

 //connect express var express = require('express'); var subdomain = require('express-subdomain'); var app = express(); app.use(express.json()); //set sub routing app.sub_banana = express.Router(); app.use(subdomain('banana', app.sub_banana)); //top level routing app.get('/', (req, res) => { res.send('I am Apple') }); app.get('/about', (req, res) => { res.send('Apples don\\'t taste good.') }); //subdomain routing app.sub_banana.get('/', (req, res) => { res.send('I am Banana') }); app.sub_banana.get('/about', (req, res) => { res.send('Apples don\\'t taste good. ** not Bananas are delicious. **') }); //start server var http = require('http'); var port = 3000 app.set('port', port); var server = http.createServer(app); server.listen(port);
