Offline

Dealing with offline

• Have the necessary application files available

• Cache server side data

• Store app state on device

Storing data

• Local Storage

• IndexedDB

Limited storage!

Ask for more through manifest

Two types of apps

• Hosted

• Assets on the server

• Cacheable via appcache

• Packaged

• ZIP archive with assets

Caching with appcache

ZIP

• One big zip file

• Resources loaded from zip file

• Still requires manifest file

One more thing...

The app manifest file

• Has name, description, version for market place

• Define permissions (calling, storage)

• Web activity provider (I provide images!)
