When I want to test on local network, I also often use Web server for Chrome:
Very light weight and super easy to use, no configuration required. Just install, run, select folder and click host. After that, you can open the project using a web browser on any device connecting to the same network.
Just make sure you have index.html in the root folder that you select.
I was not sure whether the question was real or just a phrase. Yes, the solution works for me. And according to http://www.perfectleads.com/marketshare/apache it is the software behind most websites.
I always use python. Just install it and then go to the directory you exported to via command line and execute python -m http.server. Then it should host on localhost:8000. Easy fast and simple yet effective.
