Modern progressive web apps (as studied in tutorial 9) allow webapps to be “installed” locally on a device. Thereby an webapp can be used when the device is offline (i.e. the backend applicaiton is not running / reachable). As soon as the device is back only, the local actions and remote changes are synced again.
Basic: The meme generator webapp can be opened also when the device is offline (i.e. the backend application not running). A custom error message should be prompted, that informs the user that without internet connection neither contents can be viewed nor edited.
Intermediate: In the offline mode, formerly created memes can be viewed
Advanced: Memes can also be created while the device is offline. They are persisted in some browser storage and will be synced with the server as soon as the webapp has a server connection again.
