Serve Static Files on Different Folders For Different domains

[ghost]

I made my own Router and i would like to serve files.
For example here is my folder nomenclature:
./i.domain.com/resources/file.png
./bin.domain.com/resources/otherFile.png

How can i serve static files depending of the domain (So One folder per domain)
IF (HOST=== "i.domain.com") THEN SERVE i.domain.com/resources/
ELSE IF (HOST=== "bin.domain.com") THEN SERVE bin.domain.com/resources/

You can do this with the following example code:

const express = require('express');
const app = express();

app.use((req, res, next) => {
    if(req.hostname === 'example.com') {
        express.static('./example.com')(req, res, next);
        return;
    }
    if(req.hostname === 'example.net') {
        express.static('./example.net')(req, res, next);
        return;
    }
    res.sendStatus(404);
});

app.listen(3000);

For hosting static files, it is better to use a reverse proxy in production. The express team also recommends this.

You can optimize your code using the express.static() middleware.

Here's the code with the middleware:

const express = require('express');
const app = express();

app.use((req, res, next) => {
    let root = '';

    if (req.hostname === 'example.com') {
        root = './example.com';
    } else if (req.hostname === 'example.net') {
        root = './example.net';
    } else {
        return res.sendStatus(404);
    }

    express.static(root)(req, res, next);
});

app.listen(3000);
