Architecture patterns, application structure, component boundaries, scalable frontend design
Eliminate UI state tearing and redundant network waterfalls. Explore normalized client caching architectures: flattening hierarchical API payloads into entity relational graphs, layered optimistic mutation stacks, reference-counted garbage collection, and multi-tab sync via BroadcastChannel.
Eliminate client-side XSS and data exfiltration in modern frontends. Explore Strict Content Security Policy (CSP) with nonces and 'strict-dynamic', the Trusted Types API for DOM sink hardening, Subresource Integrity (SRI), and cross-origin isolation invariants in Next.js and single-page apps.
Scale enterprise design systems across multi-brand frontends. Learn 3-tier token pipelines using the W3C DTCG standard and Style Dictionary, headless component contracts with the Slot delegation pattern, zero-runtime CSS variables theming, and automated WCAG accessibility validation.
Build production-grade frontend observability architectures. Explore OpenTelemetry in the browser, W3C Trace Context propagation across BFF boundaries, main-thread jank diagnostics with the Long Animation Frames API (LoAF), and non-blocking telemetry export via the Beacon API.
Master the architectural boundaries of React Server Components. Explore the React Flight serialization protocol, data tunneling across client/server seams, progressive streaming SSR with Suspense, and defensive security invariants using object and value tainting to prevent data leaks.
Optimize Interaction to Next Paint (INP) across complex frontends. Deconstruct interaction latency into input delay, processing duration, and presentation delay. Learn cooperative main-thread scheduling architectures using scheduler.yield(), prioritized task queues, and visual frame unblocking.
Design production-grade offline-first frontend architectures. Explore durable client storage via IndexedDB and StorageManager, multi-tab coordination with Web Locks, conflict resolution using CRDTs versus server-reconciliation, and resilient optimistic mutation queues with automatic rollback.
