Namaste Frontend System Design -

In the Namaste framework, performance is designed on day zero, not during QA.

Critical Metrics to Model:

The Namaste Rule: If a user on a 3G network with a Moto G4 can render your app in under 5 seconds, you have passed.

The course utilizes popular industry examples to teach system design interviews and real-world architecture:

Here is how your feature folder should look (using React as an example):

src/
├── features/
│   └── product-detail/
│       ├── components/
│       │   ├── ProductImage.tsx (Lazy loaded)
│       │   ├── ProductReviews.tsx (Lazy loaded)
│       │   └── AddToCartButton.tsx
│       ├── hooks/
│       │   ├── useProductData.ts (Uses React Query)
│       │   └── useAddToCart.ts (Uses Mutation)
│       ├── api/
│       │   └── productAPI.ts (Single responsibility)
│       └── types/
│           └── product.types.ts

The Data Fetching Flow (React Query):

// useProductData.ts
import  useQuery  from '@tanstack/react-query';
export function useProductData(productId) 
// Query for product details
const productQuery = useQuery(
queryKey: ['product', productId],
queryFn: () => fetchProduct(productId),
staleTime: 5 * 60 * 1000, // 5 minutes
); In the Namaste framework, performance is designed on
// Query for recommendations (depends on product)
const recommendationsQuery = useQuery(
queryKey: ['recommendations', productId],
queryFn: () => fetchRecommendations(productId),
enabled: !!productQuery.data, // Only run after product loads
);
return  productQuery, recommendationsQuery ;

This module deals with the macro architecture—how the application is delivered to the browser. The Namaste Rule: If a user on a

You cannot design a system without choosing your rendering architecture. Each has a trade-off.

Namaste Approach: Never assume SSR is always better. Measure TTFB (Time To First Byte) vs. TTI (Time To Interactive). A poorly hydrated SSR app is slower than CSR.

The term "Namaste" (a respectful greeting) in the context of technical learning, popularized by educators like Akshay Saini, implies a ground-up, core understanding. You don't just learn syntax; you learn the essence.

Namaste Frontend System Design is the art of designing complex frontend applications by first honoring the fundamentals: the browser, the event loop, the rendering pipeline, and the network stack. It rejects the notion that throwing Redux or Next.js at a problem automatically solves it.

Instead, it asks:
