Code Review

This pull request from Snyk upgrades nodemailer from version 2.x to 7.x to resolve a security vulnerability. This is a major version upgrade that introduces significant breaking changes. The application code that uses nodemailer will need to be refactored to be compatible with the new version's API. Additionally, the nodemailer-smtp-transport package, which is also present in the dependencies, is now obsolete and should be removed. Without the necessary code changes to adapt to the new nodemailer API, the application is highly likely to break at runtime.

[gemini-code-assist]

This major version upgrade of nodemailer from v2 to v7 introduces significant breaking changes that will likely break the application at runtime.

1. API Changes: The way a transporter is created has changed. The application code using nodemailer must be updated to align with the v7 API.
2. nodemailer-smtp-transport is obsolete: The nodemailer-smtp-transport package (on the next line) is deprecated and no longer needed for nodemailer versions 3.0 and above, as SMTP transport is now built-in. This package should be removed from package.json.

For example, creating a transport would need to be updated:

Old code (v2.x with nodemailer-smtp-transport):

const nodemailer = require('nodemailer');
const smtpTransport = require('nodemailer-smtp-transport');

const transporter = nodemailer.createTransport(smtpTransport({
  host: 'smtp.example.com',
  // ... other options
}));

New code (v7.x):

const nodemailer = require('nodemailer');

const transporter = nodemailer.createTransport({
  host: 'smtp.example.com',
  // ... other options
});

This PR is incomplete as it only updates the dependency version. To prevent runtime failures, the corresponding application code must be refactored, and the obsolete nodemailer-smtp-transport dependency should be removed.
