Can you explain the distinction between mongoose.save() and passport-local-mongoose.register()?

Can you explain the distinction between using mongoose's .save() and passport-local-mongoose's .register() functions?

Why is it that passport-local-mongoose's .register() function only requires a username and password? Wouldn't it be beneficial to also include fields for email or address?

Answer №1

The purpose of the `.register()` function is outlined below: passport-local-mongoose/blob/main/index.js

  1. Instantiate a new instance if user does not already exist
  2. Verify that the username is provided
  3. Check if the username is already in use
  4. Assign the password to the user
  5. Save the user by using `user.save()`
  6. Ensure that a callback function exists, and if so, return the result using `cb`

You have the option to specify a custom `usernameField` in the configuration:

User.plugin(passportLocalMongoose, { usernameField: "email" });
