Answer 1

used https://www.npmjs.com/package/uniqid in npm

npm i uniqid

It will always create unique id's based on the current time, process and machine name.

• With the current time the ID's are always unique in a single process.
• With the Process ID the ID's are unique even if called at the same time from multiple processes.
• With the MAC Address the ID's are unique even if called at the same time from multiple machines and processes.

Features:-

• Very fast
• Generates unique id's on multiple processes and machines even if called at the same time.
• Shorter 8 and 12 byte versions with less uniqueness.
