| Offline mobile app has great potential. | |
| -- | |
| This is called for. -- よびかけ? | |
| This is my question. | |
| Currently, most of the web application requires network access frequently. | |
| Some mobile native application also requires network! | |
| I want to use apps without taking care of network! | |
| -- | |
| I feel gaps between asset pipeline and rack-offline. | |
| I don't have solution, yet. | |
| I learn about offline application from railscast last year. | |
| But now it does not work. | |
| How many people do you know offline app topic on railscast? ok. | |
| So I tell the way how to be achieved, and where I have confused. | |
| If you know the de facto solution, or the alternative way, Please tell me. | |
| Or let's hack together! | |
| -- | |
| Image, you are mobile application user on your phone. | |
| iphone, android, blackberry, everything ok. | |
| You get subway, or gap of building, then you will see: | |
| "NETWORK ERROR! PLEASE TRY AGAIN LATER!" | |
| You think: | |
| My selection is lost? | |
| Usually this is saved on draft area, but sometimes data lost. | |
| -- | |
| I meet html5 cache manifest. | |
| I declair manifest file. | |
| Then web browser read this and store files which is not changed. | |
| But list up manually is too tired work. | |
| -- | |
| I meet rack-offline. | |
| Details you can reffer railscast episodes at 247 and 248. | |
| In summary, you make simple CRUD application with jQuery. | |
| That becomes offline application with rack-offline and jquery-offline. | |
| -- | |
| This is rack-offline. | |
| This is rack middleware. | |
| This gathers static contents. | |
| rack-offline detects file modification, then this refleshes manifest's hash. | |
| In development environment, this hash changes when you reload every time. | |
| -- | |
| This is jquery-offline. | |
| You create app with jQuery.getJSON, then you change jQuery.retrieveJSON. | |
| This uses local storage. | |
| -- | |
| This stores serialized sending data to local storage. | |
| If server is down, this app acts as nothing error. | |
| Merge getting remote data and local one. | |
| Send items background when network recover. | |
| If you write so. | |
| Set event fire with on-network. | |
| -- | |
| I meet after rails3.1 and Asset Pipeline | |
| You write application.js by this comment like syntax. | |
| //= require jquery | |
| //= require jquery_ujs | |
| //= require_tree . | |
| -- | |
| Result, I feel gaps between rack-offline and asset pipeline! | |
| -- | |
| paths | |
| -- | |
| engines | |

| my temporary solutions | |
| -- | |
| question in rubyonrails-talk | |
| no response ;) | |
| -- | |
| I should parse '//= jquery' and search and get whether this is updated or not, don't I? | |
| It's too hard. | |
| -- | |
| I re-implement tilt gem which bring foo.js.coffee.erb to foo.js. | |
| don't I? | |
| This is grunt and/or watchr and/or guard's solution area? | |
| -- | |
| I don't have clear solution, yet. | |
| If you know the de facto solution or the alternative way, | |
| please tell me. | |
| Are you interested in offline application? | |
| Let's talk with me and hack together! | |

ちょうどhtml5 cache manifestについて興味を持っていたので勉強になります。
refleshs -> refreshesでしょうか？
