Custom middleware is a legacy option, since most times you just want to use policies.

HOWEVER! There are times you want to use sails for quick/dirty things you would normally use express for (but you already have sails around, w/e). More pertinently, if you want middleware to run before the static files from your assets folder are served, policies won't let you do that.

Here's an example of using the BasicAuth middleware for everything:

// Put this in `config/express.js`

#Overview drip is an awesome command line tool that can be used to dramatically lower perceived JVM startup time. It does this by preloading an entirely new JVM process\instance and allowing you to simply use the preloaded environment. This has extraordinary results with jruby.

We reduced time to run rake environment from 13 seconds to a mere 3.5 seconds. This is actually at or near MRI 1.9.3p327 (with falcon patch) speeds!

Adding a few addition jruby options will reduce startup time even further (down to 1.69 seconds).

#Install Drip Install drip if you haven't already (see https://github.com/flatland/drip)

backbone: what you'd normally use jquery plugins for, but with an inverted rendering process (js -> DOM instead of DOM -> js)
"islands of richness", jquery data callbacks main pattern.

other frameworks are building out from jQuery's central pattern of DOM selection and event callbacks.
fantastic pattern for adding behavior to documents, but we aren't writing documents.
