Middleware routing (One ip server multiple domains redirection )

Hi guys,

I need some help.

How can i change this (Work!):

    app.use(require('./_appOne/routes'));

to this (Not Work):

app.use((req, res) => {
         //Get the hostname
         let hostName = req.headers.host.split(':')[0];

         //switch between projects
         switch (hostName) {
            case 'mydomainone.com':
                  require('./_appOne/routes')
                  break;
            case 'mydomaintwo.com':
                  require('./_appTwo/routes')
                  break; 
         }
});

One ip server multiple domains redirection

For starters, your let statement appears like it may return "http" or "https", at least from what I can find in a quick search. So, I suspect that what your switch statement is looking for will never happen.

Typically, under Apache or nGinx, you configure the web server itself to capture and direct the requested domain name. I think from your code, you could be working with Node.js as your web server, and I won't be able to help you there.

I found a solution to my problem.

NodeJs + Express Routing

var bouncy = require('bouncy');

var server = bouncy(function (req, res, bounce) {
    if (req.headers.host === 'beep.example.com') {
        bounce(8001);
    }
    else if (req.headers.host === 'boop.example.com') {
        bounce(8002);
    }
    else {
        res.statusCode = 404;
        res.end('no such host');
    }
});
server.listen(8000);

However, would like to know if this would be the best option (from a performance standpoint). Because I actually have to have three scripts to run instead of one

  1. Bounce main server
  2. First App
  3. Second App

will it be too heavy for the raspeberry pi?

I don't know for sure it would work, but try just adding a return before the require statements in your initial code.

Alternatively, assign each of the separate routes to variables, and choose one to be your default and change to using a ternary statement so it will use one or the other:

const appOneRoutes = require('./_appOne/routes');
const appTwoRoutes = require('./_appTwo/routes');
let routes;

app.use((req, res, next) => {
    let hostName = req.headers.host.split(':')[0];
    routes = hostName === 'mydomaintwo.com' ? appTwoRoutes : appOneRoutes;
    next();
});

app.use(routes);
