You do not need a counter, as the 100s-nanoseconds interval and a good random number should be enough to avoid a collision. GUID (Globally Unique Identifier) or (UUID) Universally Unique Identifier is a 16 byte binary value and are identifiers designed to provide certain uniqueness guarantees.

), and the UUID uses something from the localhost (a mac address for instance). In previous article, I have explained about Uniqueidentifier (GUID/UUID) in SQL Server, now in this article, I am going to provide few possible ways to generate GUID / UUID using Javascript. Other tools like databases use it too (like MongoDB)īeside your parameters (time and random number), you need another one, to avoid collision between 2 separate instances that reach the same random at the same time (I know that is far fetched. package/uuid seems to respect the standard.
You do not need to invent a new one, just read the specs or use the npm package: UUID is pretty standard, and already has 5 version of algorithms.
