问题 I need to make a POST request and send some data. I'm using the service worker sync to handle offline situation. But is there a way to pass the POST data to the service worker, so it makes the same request again?

问题 I have a chat web application and I want it to work offline. For this I use progressive web apps features (Service Workers) to use cache to get the shell app and the messages already loaded. What I want to do is to be able to make a post message when I'm offline and let the service worker handle the connection issues (i.e.: keep the message somewhere till where are offline and as soon as we are online send the Post message). I want to use Service Worker because I also want to send the message

问题 I am new to PWA and have been testing my PWA project using firebase console database.
