Tanus is a really promising Node.js “single-page app” framework (that’s really much more than that). It’s just unbelievably fast, and built on top of really solid principals:
- First request is server-side rendered (as are non-JS/spider requests)
- Progressively enhances with client-rendered future requests
- Content is served first; everything else (including non-critical CSS) is delegated to post-onload
Here’s the project page: taunus/taunus
And take a look at the creator’s blog, which is running on tanus: PonyFoo — the site speed is incredible for a blog with not insignificantly-sized pages. I’m seriously considering Tanus for a future project.
