Ask HN: Why did Frontend development explode in complexity?
Early react team member here. The popular react/webpack/npm stack is probably what the OP is talking about. It was popularized because the Instagram web team used webpack and npm in 2013 so we recommended it alongside react in the early days. I was TLM of the team when we made these decisions.There are three main points I want to add to the conversation.1. UIs actually have a lot of complexity. The number of states they can be in is often higher than what you see in other disciplines of software engineering. They also have to contend with managing data fetching over unreliable networks, including balancing bundle size. Additionally they are notoriously hard to test because “does this feel right to a user” is hard to encode programmatically.2. The grass isn’t greener on the other side. I see a lot of people complaining about the needless complexity of the frontend stack but I don’t think they’ve worked in a modern backend engineering or data engineering project. Modern backend eng is a morass of kubernetes configuration, needless microservices and overuse of async queues, for example. Feels a lot like frontend in terms of accidental complexity. So I’d argue that this is less of a frontend problem and more of an industry wide thing (cynically, it might be a ZIRP thing)3. With that said there certainly is needless accidental complexity in frontend and I am convinced content marketing is 100% to blame. An easy way to hire engineers is to create an open source project and write a blog post convincing people to use it. This is good for the company and good for the careers of the engineers who worked on it, but can cause people to needlessly complicate their tech stack if they can’t cut through the noise.
