About the Course

For richly interactive dashboards, SaaS workspaces, and enterprise internal tools, the SPA (Single Page Application) architecture remains a premier engineering choice. Building a maintainable SPA, however, requires orchestrating a cohesive ecosystem of client routing, server-state caching, form validation, and build tooling beyond the core UI library.

This hands-on course teaches developers how to architect production SPAs using Vite, modern routers (React Router / TanStack Router), TanStack Query for asynchronous data synchronization, and advanced bundle optimization.

Target Audience and Prerequisites

  • Frontend engineers building complex dashboards, B2B portals, and interactive web applications
  • Developers looking to solve bundle bloat, waterfall requests, and state synchronization issues in existing SPAs
  • Working knowledge of JavaScript/TypeScript and a component library (such as React or Vue) is required

Key Takeaways

  • SPA Architecture & Tooling: Evaluate modern UI libraries and structure scalable, feature-based SPA codebases with Vite
  • Advanced Client-Side Routing: Implement nested layouts, authentication route guards, data loaders, and type-safe URL search params
  • Server State with TanStack Query: Master caching, background refetching, optimistic updates, and paginated/infinite queries
  • Bundle & Runtime Performance: Apply route-based Code Splitting, Tree Shaking, list virtualization, and memory profiling

Curriculum

Modern SPA Architecture, Rendering Models, and Vite Tooling
  • Architectural trade-offs between SPA, MPA, and SSR for enterprise applications
  • Comparing Virtual DOM reconciliation and fine-grained reactivity across modern SPA libraries (React, Vue, Solid)
  • Configuring Vite build pipelines, environment variables, dev proxies, and feature-based folder architectures
Client-Side Routing, Data Loaders, and Access Control
  • History API fundamentals, nested layouts, and type-safe routing with React Router and TanStack Router
  • Eliminating network waterfalls using Route Loaders, route prefetching, and the Render-as-You-Fetch pattern
  • Implementing protected routes, RBAC authorization guards, and storing filter/pagination state in URL Search Params
Server-State Synchronization with TanStack Query and Forms
  • Separating Server State from Client UI State and using lightweight stores like Zustand
  • TanStack Query deep dive: query keys, staleTime vs gcTime, background refetching, and cache invalidation
  • Handling mutations, Optimistic Updates, infinite scrolling, and schema-validated forms with React Hook Form
Bundle Optimization, List Virtualization, and Production Resilience
  • Route- and component-level Code Splitting, Tree Shaking, chunk strategies, and bundle visualization
  • Rendering massive datasets smoothly using list virtualization (TanStack Virtual)
  • Global Error Boundaries, client telemetry (Sentry), memory leak debugging, and Service Worker caching
