Email Services Implementation

[almeiphi]

Develop the /email route within the NestJS backend to facilitate email sending capabilities. This route will be designed to integrate with cloud providers like Azure Communication Service (ACS) and AWS to send emails. It should process incoming email requests, validate input data, and use the appropriate SDKs to dispatch emails.

Requirements

1. Endpoint Definition

   • Define a POST endpoint at /email/send to manage email sending requests.
   • Ensure flexibility for integration with various cloud-based email services.

2. Request Validation

   • Validate incoming requests to include essential fields: to, subject, and body.
   • Optionally manage fields such as cc, bcc, and attachments.

3. Cloud Service Integration

   • Integrate with ACS and AWS email services using the necessary SDKs.
   • Provide meaningful responses to the client upon errors.

4. Environment Configuration

   • Securely store connection strings and configurations in environment variables.

5. Error Handling

   • Establish comprehensive error handling for issues like invalid input or service errors.

6. Logging

   • Record all email sending attempts and results for audit purposes.

Resources

• Azure Communication Service Email SDK
• AWS Email Service Documentation
• NestJS Documentation

Acceptance Criteria

• [ ] The /email/send endpoint is fully implemented and handles email requests.
• [ ] Request validation ensures all necessary fields are present and properly formatted.
• [ ] Emails are dispatched using ACS and AWS services.
• [ ] Error handling and logging mechanisms are comprehensive and effective.
• [ ] The endpoint undergoes thorough testing for functionality, security, and reliability.
• [ ] Configuration uses environment variables securely.

Additional Information

• This task is a critical component of Phase 2 in our development roadmap.
• The integration with cloud services must be robust, handling all potential errors with grace.
• The service should be reviewed and approved by the team for final implementation.
