Offline capabilities

[syc-pad]

Hello,

The project is working fine, but what about the offline capabilities ?
AWS docs say its SDKs allow offline capabilities, but I made some tests running the app in the browser with ionic serve and cutting the wi-fi, and I've got obviously this error :
POST https://dynamodb.eu-west-1.amazonaws.com/ net::ERR_INTERNET_DISCONNECTED

I didn't find a very clear answer neither on the web, nor in AWS docs.

Thank you for you help.
