从其他端口（CORS）访问Expressjs资源

Question

I've got one development environment on localhost:3050 and another running on localhost:3000.

I've got various static files being served as mounted directories from :3050, eg:

app.use('/app',express.static(__dirname + '/app'));

I've configured Access-Control-Allow-Origin so that CORS requests from :3000 to :3050 are permitted. Indeed the request goes through, but the application which is expecting to find files on http://localhost:3000 , can't.

I'm aware of options of proxies or setting up an SSH - would these be a good idea for this use case?

I would have thought express should have some kind of way to adjust the domain:port location for the hosting of files - hoping I might just be missing something.

Answer 1

Try this cors package. It works magically in some cases.
