email-mailtrap

You can send email notifications in NestJS by implementing the Ports & Adapters pattern, which defines a provider-agnostic notification service port. This decouples your business logic from the email provider, allowing you to swap services easily without rewriting core application code.

The Ports & Adapters pattern for email delivery separates notification logic from provider-specific implementation using interfaces. You should use this pattern when you need an architecture that allows easy swapping of email providers and simplifies unit testing of notification triggers.

Yes, Mailtrap works with TypeScript by using an adapter that supports environment-driven configuration for sandbox and production modes. You can safely test predefined email templates with data-driven rendering in the sandbox mode before switching to production delivery.

You configure Mailtrap API tokens and sender details by setting environment variables in your backend application. This environment-driven approach securely manages credentials and controls whether the notification system operates in sandbox or production mode.

Yes, you can switch email providers because the notification service is built as a provider-agnostic port with a dedicated Mailtrap adapter. Replacing the adapter with another provider's implementation allows you to change delivery services without altering business logic.
