Frontend engineering isn't just about pixel-perfect UI anymore. It’s about building resilient systems. If you’re coming from a backend background, you might think frontend is just "HTML, CSS, and some JS." But modern frontend architecture now mirrors backend system design in complexity and scale. We aren't just building pages; we're building distributed applications that run in the user's browser. I just read a fantastic deep dive by Neo Kim and Shefali Jangid on Frontend System Design that breaks down the concepts every senior engineer needs to master, including: Rendering Patterns: The trade-offs between SSG, ISR, SSR, and CSR. Micro Frontends: Scaling development across multiple teams. Performance: CDNs, Edge Delivery, and caching strategies. Reliability: CI/CD pipelines and observability for the client side. Whether you are a frontend veteran or a backend engineer looking to understand the "other side," this is a must-read.

Finally someone mentions some of the common complexities of the modern frontend development, comparable to backend system design challenges. By the way, it's not just limited to these things. These are just the first obvious ones that come to mind. Real Frontend Engineering is mainly about shaping the best possible experience for the end users & keeping the customers extremely satisfied. Unfortunately the predominant narrative of a frontend is still a translation of UI paintings of Figma handoffs & connecting them to backend APIs & ignoring any other things for a very simple reason: Building an exquisite user experience is not a priority for most companies anymore because it's not directly tied to the revenue. So if the forms are just sending the data correctly & they are tolerable, the rest is considered a waste of the company's investments & time. That's why everyone gets a terrible experience of working with most websites even at the age of bleeding-edge AI advancements & AGI claims. TLDR: The art of UX is not considered important anymore because it's not heavily tied with the product revenue. #Frontend #UX #systemDesign #designSystems #softwareEngineering
