This is a question related to my other question OpenLayers/jQuery without CDN?. I was looking to copy a minimal set of files on js/css files to replace online CDNs, so that I can run a test server on localhost without internet access.
I heard from the comments that it is possible to use
node.js to run a test server entirely on the localhost. This is a interesting approach. I was wondering what are the general steps, e.g. to run such a webgis server with (or that matches) typical options like OpenLayers and GeoServer?
