How to serve static files with a folder different for each domain

[ghost]

Let's say my code architecture is
./index.js
./localhost/resources/
./127.0.0.1/resources/

How can i serve my static files depending of the domain used (localhost/127.0.0.1)

What I understood is this?

app.use(express.static(path.join(__dirname, 'public')));

Not what i asked.
I want to run a single express server with two domains.
I want each domain to have a different folder for resources
./index.js (express server)
./127.0.0.1/resources/picture.png
./localhost/resources/profile.jpeg

How can i do that

127.0.0.1/ and localhost is the same do you want to do 2 server express and share static files?

separate the files in different folders since they would be different servers

example:
localhost:3000/resources
localhost:5000/resources

and if you want to have something in common you can use paths to use some files like app.js separate them into 2 servers with a module.exports

I want to do that in a single Server. This is the point of my issue.

Yes you can do that

Try this codes;

const handler1 = express.static(`resources_folder1`);
const handler2 = express.static(`resources_folder2`);


app.use('/resources', (req,res,next)=>{
    const origin = req.get('host')
    if(origin === "localhost"){
        handler1(req, res, next)
    }
    else if(origin === "127.0.0.1"){
        handler2(req, res, next)
    }
})

Hey i used your example and this is the final result (for anyone passing by for the same issue)
I basically have a Router Class with a method to add a domain (that load the routes, the loggers, the paths etc . .)
And here was the final result:

AddDomain(domainName)
{
    if (fs.readdirSync(`./${domainName}/resources`)) 		
         app.use(`/resources`, express.static(`${domainName}/resources`)); // Assets
}
