Do any have any good suggest some good library which creates an alphanumeric key which will not repeat again?

@samyt can you explain your use case a bit more?

@David Durst Yes you are correct.

ok do you have a candidate key(s) in your data set?

Unfortunately, No.

what about if you added a time stamp to it?

I was tried using UTC timestamp. But it kinda long

Ah so you have a limit on your key length

If I limit it may repeat in future?

but those keys are much longer than a timestamp

It just for identifying the records based on key

The only thing that comes to mind to solve this is a hash

How long will the key be?

128bits

ok

32 characters

OK Thanks

What you are looking for is called a "uuid". There are libraries, but this answer has a pretty simple implementation that is probably good enough for many use cases. https://stackoverflow.com/a/2117523

Thanks @michoel

If you're doing this server side in NetSuite you'll need a library that doesn't depend on the

crypto

api built into the browser. I had to do this a while back and ended up using https://www.npmjs.com/package/crypto-js. If you're doing it client side then @michoel’s suggestion is probably easier.
