5.6.7. Offline Capabilities
Warning
|
Experimental! The technologies listed below are not supported by all browsers yet (e.g. service workers are [not implemented](https://jakearchibald.github.io/isserviceworkerready) in Safari). |
Currently, together with the Polymer we offer to use Progressive Web Applications techniques such as web app manifest 2 to have native-like presence on the user’s homescreen. See the manifest.json
file in Polymer client module.
There are two main approaches:
-
Service Workers which primarily used to cache the app itself. Take a look at
sw-precache-config.js
file generated with Polymer client. In order to enable service worker generation set"addServiceWorker": true
inpolymer.json
.
More info on how to setup and use service workers can be found here.
-
Local storage and Indexed DB which used to store data locally. This functionality exposed in the corresponding Polymer elements: app-localstorage-document app-indexeddb-mirror.
