Nano ID

A tiny and fast Go unique string generator

• Safe. It uses cryptographically strong random APIs and tests distribution of symbols.
• Compact. It uses a larger alphabet than UUID (A-Za-z0-9_-). So ID size was reduced from 36 to 21 symbols.

id, err := nanoid.New() //> "i25_rX9zwDdDn7Sg-ZoaH"
if err != nil {
    log.Fatalln(err)
}

Installation

Once Go is installed, run the following command to get Nano ID.

Thanks to

• Andrey Sitnik for the original JavaScript algorithm implementation.
• Paul Yuan for letting me improve the Python version of the library. Without the previous work, I would not be able to fully understand the algorithm.
