Implement subscription-tier aware API rate limiting with sliding window algorithm. Use when building SaaS APIs that need per-user or per-tier rate limits with Redis or in-memory storage.
Validate API requests with schemas, sanitization, and helpful error messages. Covers Zod, Joi, and Pydantic patterns.
Fixed timestep game loop with interpolation for frame-rate independent physics. Separates physics updates from rendering, prevents spiral of death, and supports hitstop/slow-mo effects.
Handle transient failures with exponential backoff and graceful fallbacks. Retry on network blips, fall back to cached data when services fail.
Configure TypeScript strict mode with additional safety flags. Catch bugs at compile time instead of production. Includes branded types, exhaustive switches, and Result types.
Implement idempotent API operations to safely handle retries and prevent duplicate processing. Use when building payment APIs, order systems, or any operation that must not be executed twice.
Collect-then-batch pattern for database operations achieving 30-40% throughput improvement. Includes graceful fallback to sequential processing when batch operations fail.
Implement secure webhook handling with signature verification, replay protection, and idempotency. Use when receiving webhooks from third-party services like Stripe, GitHub, Twilio, or building your o...
Store failed jobs for replay or manual inspection. Track failure patterns, enable manual intervention, and prevent data loss from processing errors.
Social feed with batch queries, cursor pagination, trending algorithms, and engagement tracking. Efficient database queries for infinite scroll feeds.
Implement Supabase authentication with SSR support. Email/password auth with automatic session management via cookies. Includes login, signup, email confirmation, and user profiles.
Manage data flow when producers outpace consumers. Bounded buffers, adaptive flushing, and graceful degradation prevent OOM crashes and data loss.
Comprehensive audit logging for compliance and security. Track user actions, data changes, and system events with tamper-proof storage.
Centralized environment variable management with validation. Fail fast at startup if config is invalid. Supports multi-environment setups (dev/staging/prod) with type-safe access.
External AI API integration with retry logic, rate limiting, content safety detection, and multi-turn conversation support for image generation.
Production-grade secure file upload pipeline with multi-stage validation, malware scanning (ClamAV), hash-based duplicate detection, and race condition protection using distributed locks.
