Im just thinking is it really necessary to implement service workers in ionic?

What are the uses of service worker?

Push notification.
Network cache
Background sync

Ans:

There is already native push notification plugin which can be more performant and styles than the web push protocol.
I think we can create a wrapper around angular2 HTTP service to act as network cache like storing the requests and responses in the local storage and then use it if the app is online
I don’t know is there any implementation of background sync which will be used to re play the requests that are stored in local storage.

But im looking for is there any framework or plugin to store the request and responses that are done automatically and use them when the app is offline.

But isn’t Ionic about mobile devices first and foremost? Ionic advertises its support for service workers and with some pride: http://blog.ionic.io/tag/service-workers/ I’ve spent most of the day yesterday setting it all app for what turns out to be a disappointment. Could Ionic make this clear somehow - as the comms are arguably misleading? Service Workers are a very desirable feature - built with mobile devices in mind. I think it is in cordova’s and Ionic (leading players in the field) interest to pursue this feature and bring it to the platform?

As a stopgap - and correct me if i’m wrong - service workers should work in ionic/cordova hosted app - where the app’s code is served from a server on install (and possibly/smartly cached - with service workers). Perhaps Ionic could provide a bootstrap setup (similar to https://ionicframework.com/getting-started/) for a hosted app where service workers can actually be taken advantage of…? Just an idea
