aslam / generate-pushid.js
Created Jun 21, 2017 — forked from mikelehen/generate-pushid.js
JavaScript code for generating Firebase Push IDs
View generate-pushid.js
* Fancy ID generator that creates 20-character string identifiers with the following properties:
* 1. They're based on timestamp so that they sort *after* any existing ids.
* 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs.
* 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly).
* 4. They're monotonically increasing. Even if you generate more than one in the same timestamp, the
* latter ones will sort after the former ones. We do this by using the previous random bits
* but "incrementing" them by 1 (only in the case of a timestamp collision).
