javascript - Running multiple Node (Express) apps on same port

Question

I have multiple Node applications (build on Express framework).

Now I have placed them like this -

• /var/www/app1
• /var/www/app2
• /var/www/app3

Now I want to run these 3 apps on the same port (say 8080). Is that possible ?

One thing to note is that, Each app has common routes like these -

• app.get('/', func...);
• app.get('/about', func...);
• app.post('/foo', func...);
• app.post('/bar', func...);

Basically I want to do it like you can do with Apache/PHP setup.

So with a LAMP stack when you have -

• /var/www/app1
• /var/www/app2
• /var/www/app3

You can easily access them as different apps from -

• localhost/app1
• localhost/app2
• localhost/app3

Answer 1

You can use app.use():

app
  .use('/app1', require('./app1/index').app)
  .use('/app2', require('./app2/index').app)
  .listen(8080);
