Imagine you’re building an e-commerce website. The homepage should load instantly for every visitor, product pages need updated pricing and stock information, the checkout page must always display the latest cart details, and the user dashboard is personalized after login. Using the same rendering strategy for all these pages wouldn’t be efficient. This is where […]
Introduction Large Language Models (LLMs) are incredibly powerful, but they have a major limitation: they are cut off from the real world. Imagine building a customer support bot. A user asks, “Where is my order #12345?” On its own, an LLM cannot fetch live database records, call a shipping provider’s API, or check inventory levels […]
Introduction A few months ago I stumbled on something that made me feel like, “wait, what?” one of our testing sites was showing up in Google search results. It wasn’t supposed to be public, it was a playground for QA and developers, but there it was, indexed and discoverable. That little surprise led to a […]
Whenever the codebase of a frontend application starts growing bigger, the initial solution seems straightforward. You just hire a couple more developers, spin up a few new feature branches, and keep pushing code into the same repository. For a while, that works perfectly fine. It’s the classic way software gets built. But eventually, reality hits. […]
Introduction Real-time systems are now central to modern businesses. Payments, order updates, customer activity, telemetry, notifications, and analytics all depend on events moving quickly and reliably between services. The challenge is not just speed. The challenge is preserving correctness and resilience when systems are distributed, traffic is variable, and failures are inevitable. Apache Kafka […]
Introduction Applications can fail in a lot of different ways – API failures, UI errors, server issues, or incorrect input from a user. When something goes wrong in a production environment, it can be difficult for people to replicate the error in their local environment. To address the above challenge in development, teams can use […]
Introduction There is no doubt that Angular is powerful. But after using Angular from v1 to v20 in real production systems, I found that most performance problems and messy codebases come from a small number of mistakes that keep happening. In this article, I’ll talk about what I’ve learned from my own projects that helped […]
Introduction Over the past few sprints, a recurring question has been: GraphQL or REST? Most discussions revolved around frontend flexibility, performance, and how much complexity we want in our APIs. For example, a mobile app often needs just user names, not full profiles—overfetching in REST can impact performance, increasing bandwidth and slowing down user experience. […]
Introduction If we have ever started a project using React or Next.js, we would have noticed two commands that look almost the same: npm and npx. Although they look similar, their uses are totally different in the web development world.In this blog, we will understand the differences between the two in simple terms with examples […]
