#Offline pages pro for android Offline

Be prepared, by pre-caching the offline pageįirstly we need to store the offline page, when the app starts. This is a common pattern in many Web Apps and will work as long as you have pages cached. If your app uses JSON to populate pages on the client side this technique still works as long as you cache both the JSON responses and the pages which show them. This app is rendered on the server so it returns all the information in the HTML page, these pages get cached by the service worker. Where the user can read an RSS feed at a URL like so: /feed/?url= This is to show a lit of relevant cached pages to the user: I’m going to propose, and build, a feature which should be useful to many apps and websites and would make your app still partly usable whilst your offline.

A useful offline page for almost any Web App Which unfortunately I can’t find a live version of any more. These pages can do even more though, they can be used to provide entertainment such as The Guardian’s developer blog providing a crossword on their offline page. These are great for maintaining a consistent user experience during network failures which is the expected behaviour of a native app. So the user still feels like they are using our web app when the connection is lost. If we haven’t anticipated this we may see the dreaded no connection message:įortunately we are very smart developers and can show a branded offline page. Sometimes the user will be trying to go to a page which hasn’t been cached yet. Unfortunately our cache isn’t always perfect.

If the network fails or takes too long to respond we can then use these cached responses to show the user the page they were looking for, letting people continue to use the app despite not being connected. Fortunately since we’re been building a web app we have a service worker which has the capability of caching network responses. In ideal conditions the user will always maintain a good connection to the web but things are seldom ideal. We can’t guarantee our users have a good internet connection but we can still be helpful when they don’t.
