Hi, is the DNS outage still a problem? Could you please let me know in a comment if the link is not working for you? Thanks a lot!
These are some NX related links in case someone is interested and can't open GitHub (they might work for you).
The live demo of the app: https://nx-hacker-news.github.io, Home page and docs: http://nx-framework.com or http://nx-nxframework.rhcloud.com (to avoid CloudFlare)
ETA: ...that said, looking at the Google results for "nx framework", one has to wonder about the quality and value of something that's touted with trumped-up rhetoric like "the best client-side JavaScript framework".
Edit: Changed it to this. 'NX is a small client-side framework built with ES6 and Web Components. It features routing, data-binding and animations among other things.'
