PushID is a Go library which generates chronological, 20-character unique IDs. It implements Firebase's push IDs, what are Push IDs?
Push IDs are string identifiers that are generated client-side. They are a combination of a timestamp and some random bits. The timestamp ensures they are ordered chronologically, and the random bits ensure that each ID is unique, even if thousands of people are creating push IDs at the same time.
