Transactional Email Patterns

Transactional email delivery pattern library for backend services — Resend (developer-friendly, React Email integration), Postmark (best deliverability, fast support), SendGrid (enterprise, complex but powerful), Mailgun (API-first, good EU compliance), Amazon SES (cheapest at scale, requires reputation management), Brevo (formerly Sendinblue, EU-based), Loops (product-led growth focus). Covers domain authentication (SPF, DKIM, DMARC), dedicated IPs vs shared pools, bounce and complaint handling, suppression lists, webhook events (delivered / opened / clicked / bounced / complained), rate limiting, retry strategies with exponential backoff, template management (inline vs stored templates), and test email flows. Use when sending transactional emails from a backend: password resets, order confirmations, notifications, welcome emails, magic links, invoices. Differentiates from marketing email (newsletters via Ghost, Mailchimp, ConvertKit) by focusing on 1-to-1 triggered emails with deliverability-critical SLAs.

MongoDB 7+ Patterns

MongoDB 7+ pattern library for Node.js and Python backends — schema design (embedded vs referenced documents, polymorphic patterns, attribute patterns, bucket pattern, computed pattern), indexes (single field, compound, multikey, text, geospatial, partial, TTL), aggregation pipeline ($match / $group / $lookup / $unwind / $project / $facet), transactions with session API (ACID multi-document since 4.0), change streams for CDC, official Node.js driver + Mongoose ODM (with TypeScript inference), Python via motor (async) + Beanie ODM, Atlas Search and Vector Search, sharding key selection, replica sets for HA, and backup strategies with mongodump + Atlas PITR. Use when designing or maintaining MongoDB schemas, optimizing slow queries, writing aggregations, implementing transactions, or migrating between relational and document models. Differentiates from postgres-patterns by covering document-oriented design patterns that don't apply to relational databases.

Real-time WebSocket Patterns

Real-time messaging pattern library for backend services — native WebSocket (ws library for Node, FastAPI WebSocket for Python, Spring Boot STOMP for Java), Socket.IO (fallback for legacy clients + auto-reconnect + rooms + namespaces), Server-Sent Events (SSE for one-way server-to-client streams), WebRTC (peer-to-peer audio/video/data channels via simple-peer or livekit-server-sdk), managed real-time services (Pusher, Ably, PubNub, Supabase Realtime, LiveKit for video), and Cloudflare Durable Objects for stateful edge WebSocket. Covers connection lifecycle (connect, heartbeat, reconnect with exponential backoff), auth patterns (JWT in query param vs subprotocol, cookie-based), message routing (rooms, channels, presence), scaling (horizontal scaling with Redis pub/sub or NATS adapter), load balancing sticky sessions, and monitoring connection counts. Use when building chat, live notifications, collaborative editors, multiplayer games, live dashboards, or real-time updates in any backend.
