📝 Walkthrough

Walkthrough

Notification storage and endpoints are added, the dashboard now lists and deletes notifications, reminder emails are sent through Resend with notification records, expired subscriptions are marked in a job, a separate job syncs EUR exchange rates, and a VS Code setting hides Postman dotenv notifications.

Changes

Notifications and subscription messaging

Layer / File(s)	Summary
Schema and migration server/prisma/schema.prisma, server/prisma/migrations/.../migration.sql	User gains notification/reminder fields and a notifications relation, Subscription loses reminder columns, Notification is added in the schema and migration, and the enum Type block is reformatted.
Notification API server/server.js, server/src/routes/notification.route.js, server/src/controllers/notification.controller.js	Authenticated notification routes are mounted, and the controller lists or deletes the current user's notifications.
Notification dashboard client/src/lib/utils.js, client/src/pages/dashboard/Notification.jsx	fetchWithAuth() now points at the local API base URL, and the dashboard renders loading/error/empty states plus delete handling with React Query invalidation.
Reminder email flow server/src/config/env.js, server/package.json, server/src/services/email.service.js, server/src/jobs/sendReminder.js	RESEND_API_KEY is added to env, resend is added as a dependency, reminder and expired email templates are added, and the reminder job sends emails and creates notification records for due subscriptions.
Expired subscription job server/src/jobs/sendExpired.js	The job marks overdue ACTIVE subscriptions as EXPIRED and disconnects Prisma after completion.

Exchange rate synchronization

Layer / File(s)	Summary
EUR rate sync job server/src/jobs/syncRate.js	The job fetches EUR exchange rates from the external API and upserts them into the database on module load.

Poem

I hopped through APIs under the moon,
Found notifications jingling a carrot tune.
I nibbled some mail and the rates in the rain,
Then bounced back home for a restart again.
🐰✨ Hop, send, refresh!
