assets_offline
====

Stable Version: 0.0.5

This gem is specifically for Rails 3.1 projects that wish to use HTML5 and its offline cache feature with the Asset Pipeline.

Installing
-———-

Installation is straight forward simply add the gem to your gemfile and do a bundle install or on the terminal as follows

$ gem install assets_offline
# Last Updated DD/MM/YYYY
application:
  asset-cache:
    - "application.css"
    - "checkout.js"
    - "favicon.ico"
    - "favicon.png"
    - "logo.png"
  cache:
    - "/dictionary.json"
  fallback:
    - "/prompts.json # /prompts.json"
    - "/prices.json # /prices.json"
  network:
    - "/checkout/start_transaction.json"
    - "/checkout/submit_transaction.json"

Documentation
-—————————-

The yaml file “assets_offline.yml” needs to be added to the rails config folder. The yaml is split by route name. So the exmaple above can be added to html using “/assets_offline/application”. You can add as many root nodes to the yaml as you require and just add the name to the path to get the generated file.

There are 6 sections to add files to in the Yaml

  • asset-cache
  • cache
  • asset-fallback
  • fallback
  • network
  • asset-network

Sections starting asset will use the rails asset_path() helper to get the file path. Non asset sections will use the path specified.
Fallback requires two paths which need to be seperated by a “#”

Manifest file generates a hash key in development this key is changed every 5 seconds so the cache will never function, in production the key is based on the hash of the yaml file. To force a cache refresh you must update the last updated value in the yaml file.

Roadmap
-———

  • Rake task to create YAML files
  • Automating key update in production mode
  • Adding directories to cache file rather than individual files

Changelog
-———

v0.0.5

  • Beta release
