what is collapse key as you have mentioned in the example?

jlcvp commented 2 years ago

collapse key is used to "collapse" an older notification of the same collapse key. For example, if I have a package tracking app and a package status is modified to IN TRANSIT, then, DELIVERED. The only information that matters to be in a notification is the last one. I can use the same collapse_key for both, so when the DELIVERED notification arrives, if the user haven't seen the IN TRANSIT the OS will replace the older notification with the newer one.

Additionally, this lib is becoming strongly deprecated and I do not intend to keep the support for it any further, please use the official firebase sdk for node.
