RailsConf 2023 - Building an offline experience with a Rails-powered PWA by Alicia Rojas

Progressive web applications (PWAs) allow us to provide rich offline experiences as native apps would, while still being easy to use and share, as web apps are. Come to learn how to turn your regular Rails application into a PWA, taking advantage of the new front-end tools that come with Rails by default since version 7. Entry-level developers are welcome!

Suppose a user clicked two times on save button, First time he clicked put request failed(Network error). Second time he clicked, it was a sucessful and response with 200 received. The stale data is still saved in index db, because of frist failed request, how to invalidate this request ?

You can start by generating idempotency keys on the client side, which now allows you to detect when it happens. You can adopt a strategy of preventing this from happening in the first place by blocking the second request at the service worker level, and leaving it to the background sync to push the first record to the backend.
