Microloader, localStorage, cache.manifest

**_piotr** · 26 Jul 2012, 6:52 AM

Hi,

I have following code in app.json:

Code:

"js": [        
{
         "path": "app.js",
         "bundle": true,  
         "update": "delta"
     }        
],

and in cache.manifest:

Code:

# d5db6d2b81a9dda1c37d6f6ce071f8892396f0fe
app.js

which changes if I update the file.

After the file has been stored in localStorage it doesn't update although a hash with new delta in cache.manifest changes. In the result a new version of my app doesn't show up in the browser (Chrome).

The app was build with sencha tools with command: sencha app build production

Do I miss something?

Thanks in advance for help.

You shouldn't put app.js in the cache.manifest, app.js will be stored in localStorage

Ok, I've removed it from cache.manifest, but it goes to localStorage and has not been updated thou.

HTML5 documentation says at when cache.manifest changes, files are going to be refreshed. Does it not work similar in Sencha with localStorage caching?

Here http://www.sencha.com/learn/taking-s...-apps-offline/ James Pearce shows an example of cache manifest:

CACHE MANIFEST
index.html
app/app.js
lib/touch/sencha-touch.js
lib/touch/resources/css/sencha-touch.css

and he puts <html manifest="app.manifest"> at the top of index.html. Should I add it manually after Sencha SDK Tool does its jobb or should I leave it as it is.

Thanks for help!

The localstorage mechanism makes an Ajax request to app.json and if successful it sees if there are any delta updates. If so then it attempts to load them. Once they are loaded it will prompt the user to refresh the page as there was an update applied.

Ok, so I see at there is an issue with external resources. I've read at it is impossible in Sencha to request external url in the way: http://url.toexternalscript.com/scripts/s.js or /scripts/s.js if it is on the same server.

When I am building an app I am getting an error at:

Code:

ENOENT, no such file or directory 'C:\[path]\m\scripts\s.js'

or

Code:

Uncaught ReferenceError: Ext is not defined

When I edit already minified app.json.

I hope you can help me with that. I've searched forum and google it but I've never found good unswer to solve the problem. Then everyone could find the way how to fix that problem.

Greetings
