A small Python HTTP URL routing facility, capable of sub-microsecond routing. This is mostly pedagogical, demonstrating what is possible to accomplish, but a little too spartan for most projects.
That said, when combined with a very fast application server, nanoroute is capable of rivaling the best routers and dispatchers in performance-oriented languages; just don't expect it to do session management or anything like that.
Nanoroute is ~4400x faster than Flask / Werkzeug.
