Module: AssetRam

Defined in:
lib/asset_ram.rb,
lib/asset_ram/version.rb

Overview

Use in views to cache the asset path computation.

Preferred usage (since v1.1.0):

= AssetRam.cache { favicon_link_tag('favicon/favicon.ico', rel: 'icon') }

The calculated asset paths are keyed by source file name and line number. The results are stored in RAM.

Sometimes, a key is needed if the code is run in different contexts, like a multi-tenant site:

= AssetRam.cache(key: site) { stylesheet_link_tag("themes/#{site}", media: nil) }

For compatibility, you can still use:

= AssetRam::Helper.cache { ... }

To test and compare if this lib actually improves performance, set the ASSET_RAM_DISABLE env var and it will transparently never cache.
