Rails erb html minification

[Roman Usherenko]

Hi!

Anyone knows a nice way to minify HTML output of erb templates in Rails? Right now I use a middleware that gsubs "\n"'s between close and open tags, but this happens on each page load and depending on a page size can be taxing on performance.

I'm looking to write some kind of a template engine (based on, or compositing Erubis), that will tap into Rails template handlers chain so that the compiled result will be cached by rails. Ideally I also do not want to change all my template files extension from *.erb to something else.

Any advises?

Hi Roman,

I don't know of any HTML-aware ERB-templates. Slim/Haml handles HTML in its syntax, and thus have way more control over what it generates. How HTML-aware do you want the template engine to be? Should it also catch invalid HTML?

I also don't know how to hook into Rails' template engine. But that's easy to figure out.
