A comprehensive guide to modern React state management patterns. It covers various state types—including local, global, server, and form state—and demonstrates best practices using industry-leading libraries like Redux Toolkit, Zustand, Jotai, and React Query. Use this when building complex, scalable React applications and needing to select the optimal state solution.

Provides reusable Redis patterns for caching, rate limiting, pub/sub, streams, Lua scripts, and distributed locking to build scalable, resilient data services.

This comprehensive workflow guides developers through building a production-ready, full-stack web application entirely within the Replit environment. It covers setting up the entire architecture, including Express/Flask backend logic, robust PostgreSQL database integration for persistent data, implementing secure user authentication using Replit Auth, and managing file uploads via Object Storage. It is the definitive guide for launching a complex, scalable SaaS project from scratch.

This guide provides comprehensive instruction on integrating with the full Replit ecosystem. Learn to monitor deployment lifecycles, set up external webhook receivers (e.g., GitHub, Stripe), build custom workspace extensions using React/TypeScript, and create complex automated workflows using Replit Agents. Essential for building scalable, event-driven applications on Replit.

Expert skill for building high-performance, memory-safe systems, web services, and complex libraries using modern Rust (1.75+). Specializes in advanced async programming with Tokio, zero-cost abstractions, and mastering ownership and lifetime rules. Ideal for implementing scalable backend APIs, low-level networking, and performance-critical components where memory safety is paramount.

This guide provides expert patterns for building robust and scalable applications on the Salesforce platform. It covers modern UI development using Lightning Web Components (LWC) with reactive data services, and teaches advanced Apex implementation. Key patterns include utilizing handler classes for bulkified triggers to prevent recursion and ensuring separation of concerns, crucial for high-performance, maintainable code.
