Frontend Diagrams

Modern frontend development spans a wide and interconnected set of concerns — from the low-level mechanics of how a browser parses and paints HTML to the architectural patterns powering today's single-page applications. This collection of 20 diagrams maps the concepts every frontend developer needs to understand deeply.

Start with the fundamentals: Browser Rendering Pipeline traces the critical path from HTML bytes to pixels on screen, and DOM Update Lifecycle shows how changes propagate through the document tree. From there, Virtual DOM Diffing explains how frameworks like React minimize expensive real DOM mutations.

On the architecture side, SPA Navigation Flow and Client Side Routing cover how modern apps handle URL transitions without full page reloads, while SSR Rendering Process and Hydration Process explain the server-side rendering model that improves first-contentful-paint and SEO. Framework-specific diagrams — React Rendering Lifecycle, Vue Reactivity System, and Component Lifecycle — demystify how state changes translate to UI updates.

Performance-focused entries including Lazy Loading Components, Code Splitting Architecture, Module Bundling Workflow, and Web Performance Optimization cover the build-time and runtime strategies that keep apps fast. Service Worker Lifecycle, Browser Caching Strategy, and Offline First App Flow round out the collection with progressive web app patterns. Every diagram is free to open and edit directly in Graphlet.
