Node.js docs on the crypto.When creating the database structure it is important to make sure that each row in a table has a unique ID so that it can be easily indexed, retrieved, and manipulated when needed.You can benefit from a package generating a UUID if you’re using already 😃 const Str = uuid = Str.uuid() The package uses the uuid package to generate a UUID v4. The package comes with a handy Str.uuid() method generating a UUID v4 for you. I’m the maintainer of the package providing convenient string utilities.
