In the world of modern front-end development, efficient data fetching is critical to building high-performance, scalable applications. With the rise of frameworks like Next.js and the popularity of SPAs, tools like SWR, React Query, and Apollo Client have emerged as the go-to solutions. But how do they compare, and which one should you use? Let’s break it down. Why You Need a Data Fetching Library While fetch and axios handle the basics, real-world applications need: Caching Background revalidation Pagination Mutation support Optimistic updates Error and loading state management That's where libraries like SWR, React Query, and Apollo Client shine. SWR (Stale-While-Revalidate) From : Vercel Best for : Lightweight apps and static site generation (SSG) Pros: Minimal API and easy to get started Excellent for SSR/SSG in Next.js Automatic revalidation and focus tracking Small bundle size Cons: Limited ...

The eCommerce world is evolving rapidly, and "Headless" architecture is at the heart of that transformation. Traditional eCommerce platforms often tightly couple the front-end and back-end, limiting flexibility, scalability, and customization. Enter Headless eCommerce —a modern approach where the front-end is decoupled from the back-end, allowing businesses to build seamless, personalized shopping experiences across any device or channel. Let’s explore what Headless eCommerce is, how it works, and how platforms like Shopify , Magento , and Commerce.js enable this model. What is Headless eCommerce? Headless eCommerce is a software architecture where the front-end presentation layer (what users see) is separated from the back-end commerce engine (where logic, inventory, and checkout happen). This decoupling allows front-end developers to use modern tools (React, Vue, Next.js, etc.) to create tailored user experiences while communicating with the back-end via...

As modern applications continue to evolve, especially with the rise of microservices, API Gateways have become an essential component in managing, securing, and scaling APIs. But what exactly is an API Gateway, and why is it so important? What is an API Gateway? An API Gateway is a server that acts as an intermediary between clients and backend services. Instead of interacting directly with various microservices, clients send requests to the API Gateway, which then routes those requests to the appropriate service, collects the responses, and sends them back to the client. In simpler terms, it’s the single entry point for all client requests in a distributed system. Key Benefits of Using an API Gateway 1. Centralized Routing The API Gateway handles all incoming API requests and knows exactly which service to forward them to, reducing the complexity for the client. 2. Improved Security Security concerns like authentication, authorization, rate limiting, and IP whitelisting can be enfor...
