remote-static

Express middleware to proxy-map local URLs to a remote host.

Usage

Simply specify the remote URL when you add your middleware:

const express      = require('express'),
      app          = express(),
      remoteStatic = require('remote-static');

app.use(remoteStatic('https://example.com'));
app.listen(3000);

Then, if you ping say, localhost:3000/path/to/asset and https://example.com/path/to/asset exists, it will be served up. If it doesn't exist, this middleware internally calls next() and the request passes through unaffected.
