Frontend Architecture
Design scalable systems, choose the right patterns, and build frontend infrastructure that lasts.
Frontend System Design
A structured framework for approaching frontend system design interviews and real-world architecture decisions.
Micro-Frontends
When and how to adopt micro-frontends: implementation approaches, trade-offs, and common challenges.
State Management at Scale
Master state architecture for large frontend applications: when to use local vs global state, library trade-offs, server state, and state machine patterns.
Design Systems
A comprehensive guide to building and scaling design systems: tokens, component APIs, Storybook, versioning, and adoption strategies.
Build Tooling Deep Dive
Understanding modern JavaScript build tools: Webpack vs Vite vs Turbopack, module systems, tree shaking, and CI/CD optimization.
Frontend Security
Essential frontend security: XSS, CSRF, CSP, authentication patterns, secure storage, and supply chain security.
Virtualization and Windowing
Master virtual scrolling for high-performance lists and tables: when to use it, library trade-offs, variable-height challenges, and integration patterns.
Performance Optimization Patterns
Comprehensive patterns for frontend performance: code splitting, lazy loading, prefetching, bundle analysis, memory management, and RUM.
Rendering Strategies
CSR, SSR, SSG, RSC, and streaming: a comprehensive guide to choosing and mixing rendering strategies for modern frontends.
Caching Strategies for the Frontend
HTTP headers, browser cache layers, CDN, application-level caching, service workers, and common pitfalls.
Monorepo Architecture
When to use monorepos, tooling comparison, workspace structure, build orchestration, and scaling challenges.
Frontend API Layer Design
Design a robust API abstraction layer between your UI and backend: REST vs GraphQL, BFF pattern, client architecture, error handling, and type-safe contracts.
Frontend Observability and Monitoring
Comprehensive guide to seeing what's happening in production: error tracking, performance monitoring, RUM vs synthetic, session replay, alerting, and feature flag observability.
Progressive Web Apps
Build installable, offline-capable web apps: Web App Manifest, service worker lifecycle, caching strategies, background sync, push notifications, and testing PWAs.
Web Workers and Multithreading
Offload CPU-intensive work from the main thread: Web Workers, Comlink, SharedArrayBuffer, worker pooling, and when to use workers vs requestIdleCallback.
Error Handling and Resilience
Build frontends that fail gracefully: error boundaries, global handlers, retry patterns, circuit breakers, optimistic updates, and postmortem culture.
