How to generate UUID using mongodb scripting

Question

I plan to write a script to alter mongodb tables and fields based on this source: https://docs.mongodb.com/manual/tutorial/write-scripts-for-the-mongo-shell/

I plan to generate a UUID and put in a new field to be added to the altered tables, I found this reference on how to generate a BSON UUID object but there's a need for me to specify a 32-byte hexadecimal string to convert to the UUID BSON subtype . Ideally I'm looking for a mongodb equivalent to this which it auto generates UUID v1 by creating a random hash itself without the need of a 32-byte hexadecimal input. How is this done? I plan to create a script on this which mongodb will execute.

Answer 1

Since I think there's no direct mongodb solution, I used this instead: Create GUID / UUID in JavaScript? , there's a fiddle which is fit for my needs.

In javascript you can use this bson-objectid library
