In the fast-paced world of front-end development, the focus is often on building sleek interfaces, optimizing performance, and managing state. However, as applications grow, so do the demands of deployment, scalability, and consistency across environments. That’s where Infrastructure as Code (IaC) comes into play. But wait— why should a front-end developer care about infrastructure ? Let’s break it down. What is Infrastructure as Code (IaC)? IaC is the practice of managing and provisioning computing infrastructure through machine-readable configuration files, rather than manual processes. In simple terms: instead of clicking buttons in a cloud console, you write code (YAML, JSON, or HCL) to define your infrastructure. This code is version-controlled, repeatable, and automated. Popular IaC tools: Terraform (by HashiCorp) Pulumi (supports TypeScript/JavaScript) AWS CloudFormation Ansible (configuration-focused) Why Front-End Developers Should Care You might not be spinning up server...

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 ...
