// Notify subscribers (e.g., React context) window.dispatchEvent(new CustomEvent('module:patched', detail: name, version: newModule.version ));

| Aspect | High‑Level Design (HLD) | Low‑Level Design (LLD) | |--------|------------------------|------------------------| | | Overall system architecture, component boundaries, data flow, and major technology choices. | Detailed implementation of individual components: state management, API contracts, component trees, and edge cases. | | Perspective | You act as a senior architect making strategic trade‑offs. | You act as an implementation specialist coding specific features. | | Examples | Designing an Instagram‑like feed system with real‑time updates and CDN caching. | Implementing a debounced autocomplete component, an infinite scroll list, or a config‑driven UI. | | Why It Matters | Helps you pass HLD rounds at top tech companies and lead architectural decisions. | Prepares you for machine coding rounds and ensures your implementations are robust, reusable, and maintainable. |

| Patch Layer | Implementation | |-------------|----------------| | | Use System.override() or Module Federation’s overrides API to replace a faulty component on the fly. | | Cache Schema Patch | Cache version header + migration layer (e.g., localForage upgrade). | | CSS Patch | Shadow DOM + constructable stylesheets to inject fixes without FOUC. | | State Patch | Redux middleware that listens for “patch” actions to update reducers without restart. | | API Patch | JSON Patch (RFC 6902) over WebSocket to update client-side API response mocks for A/B testing. | namaste frontend system design patched

Use libraries like DOMPurify to clean raw HTML before rendering.

In the original context, "Namaste Frontend System Design" is an approach that teaches: // Notify subscribers (e

Attach custom headers (e.g., X-XSRF-TOKEN ) extracted from a secure client-side cookie to every state-changing HTTP request. 3. Subresource Integrity (SRI) Patches

The course dedicates entire sections to both levels of design, a structure rarely found in frontend‑focused resources: | You act as an implementation specialist coding

The "patched" methodology refers to a mindset of continuously refactoring, auditing, and upgrading critical operational pillars—such as communication layers, security filters, state synchronization, and asset loading—to keep enterprise web ecosystems highly performant and secure.
