Mar 17, 2016 (6 replies) Hi all, I'm struggling with getting a random child using firebase, without having to download all the snapshot. Let's say I want to get info of a random users, since their keys aren't exactly integers, how am I supposed to get a random one? I've been trying to play with the limitToFirst and Last and endAt etc, but I just can't find a way. I'd suggest reading through the Firebase documentation. Specifically, see the Saving Data portion of the Firebase JavaScript Web Guide. From the guide: Getting the Unique ID Generated by push Calling push will return a reference to the new data path, which you can use to get the value of its ID or set data to it.

Generate random time-based, collision-proof IDs a la Firebase.push. Designed for testing and education (readability), not performance.

API

generate(now) -> String

firebase-auto-ids exports a function. Pass in now, the current timestamp (e.g. Date.now()). generate returns an ID string. Like Firebase.push, IDs hold the following properties:

  • id1 < id2 where id1 was created at an earlier time (now) than id2
  • id1 < id2 where id1 and id2 were created at the same now but generateAutoId was executed for id1 before id2
  • id1 ! id2 where id1 and id2 were created at the same now in different clients
new generate.Generator() -> generator

Creates a new generator instance. Individual instances do not share state. This means that IDs created at the same time in a given runtime will no longer be determined by call order.

generator.generate(now) -> String
