I <3 the Asset Pipeline

I <3 the Asset Pipeline

People talk shit on Sprockets and the Asset Pipeline all the time. I get it. It's pretty confusing and when it breaks it can break in really undesirable ways. I was originally very sceptical, and I strongly considered upgrading to Rails 3.2 with sprockets disabled.

I didn't, and I'm glad I've stuck with the pipeline. Here's why:

  1. If you're using digested assets (by default you are), asset expiry just works. No cache clearing during dev, no "wait a few minutes for the CSS to expire", no expiring every asset on every deploy, no deployment issues where people get new HTML and old CSS or JS. Sprocket's digest strategy has so far been excellent and I'm glad it's there.

  2. SASS and CoffeeScript just work. No running guard or compass to watch and auto-compile your shit, relatively seamless integration into Rails, and effective separation of vendored code from application code.

Conversion of year/month/day to day since epoch, and back (with weekday)
#define OFFS -306 /* Offset to epoch-day (Day 1 is 1/1/0001) */
#define WD 0L /* Day of week offset */
/*
* datol: takes a YMD date, and returns the number of days since some base
* date (in the very distant past).
*
* Handy for getting date of x number of days before/after a given date.
* A date is valid if ltodate() yields the same YMD you started with.

Using Backbone.View with regular (read: not all rendered in JS) HTML pages.

The idea is you can still use Backbone.View to structure components in the screen. Run the code below with each page render.

In CoffeeScript:

$ ->
  for el in $('[data-view]')
    $el = $ el
    viewName = $el.data 'view'
    view = window[viewName]

new view(el: el) if view?
