The Node require method that loads source files, compiles and caches them is ok, but could be
made a lot more powerful. Luckily one can replace the built-in require in user space without
much effort. In this presentation I will show how to
use your own require version with extra features, like cache busting and passing extra variables
or loaded code transformation.
speed up application startup by 25% with a single require include to avoid path hunting.

I will base the presentation explaining the module loading logic and
the javascript tricks (like faking lexical scope) that allowed me to implement the following
interesting projects:
