In today’s landscape of scalable and modular software development, microservices have emerged as the go-to architecture for building complex applications. One of the key advantages of microservices is the clean separation of concerns — especially between the front-end and the back-end. This separation enables faster development, improved maintainability, and seamless scalability. What Are Microservices? Microservices are small, independently deployable services that communicate over lightweight protocols like HTTP or messaging queues. Each microservice is responsible for a specific business function and can be built using different languages, databases, or frameworks — making the system highly modular. Front-End and Back-End Separation Separating the front-end from the back-end in a microservices architecture involves: Creating a standalone front-end application (SPA or MPA) that consumes APIs exposed by individual microservices. Ensuring each microservice pro...

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 APIs continue to be the backbone of modern web and mobile applications, developers are often faced with a key decision: GraphQL or REST ? While both serve the purpose of data exchange between client and server, they do so in fundamentally different ways. So how do you choose the right one for your project? Let’s explore both technologies, their strengths and weaknesses, and when to use what. What is REST? REST (Representational State Transfer) is an architectural style that uses HTTP methods like GET, POST, PUT, and DELETE to interact with resources. It has been the de facto standard for APIs for years. Pros of REST: Simplicity: Easy to understand and implement. Stateless: Each request contains all necessary information, enhancing scalability. Wide Adoption: Mature ecosystem, tools, and support. Caching: HTTP-level caching is straightforward. Cons of REST: Over-fetching/Under-fetching: Clients often receive too much or too little dat...
