​
Implementation

The main logic can be found in the service-go-user/domain/email/provider.go file. The local provider is a mock implementation that doesn’t require any configuration. It logs the email content to the console.

​
Configuration

This choice can be made using the GoFast CLI or by modifying the docker-compose.yml file.

​
via CLI

Possible options are Postmark, SendGrid, Resend, AWS SES and Local (log)

​
via Docker Compose

Possible options are postmark, sendgrid, resend, ses and local.

​
Emails Configuration

Depending on the provider, you need to set the following environment variables in the docker-compose.yml file:
  • for postmark, set POSTMARK_API_KEY.
  • for sendgrid, set SENDGRID_API_KEY.
  • for resend, set RESEND_API_KEY.
  • for ses, set SES_ACCESS_KEY, SES_SECRET_KEY, and SES_REGION.
  • for local, no configuration is needed.
