serve-static-with-parameters

Serves files with names where the base file name and base URL path match. An example would be serving a file /some/path/to/styles.css?ver=1234 in response to an URL /some/path/to/styles.css?version=abc. That is, it ignores the URL parameters portion in both URL and file name.

If an acceptable matching file exists that express's static-serve module would serve, this module will either take no action or change the request's path to point to it. That's because this module does a horrible job of adding and handling cache headers (it doesn't). If a file can be served by express's built in module, that's better.

Use like:

const staticServer = require('serve-static-with-parameters')
app.use(staticServer(filesDir))

Why

The reason to do this is that when you mirror a site, many of the file names can contain version strings. You can't use express to serve a static mirror of the site unless you can serve the files with those strings.
