What 'Modern' Web Application Development Actually Means

It's tempting to define 'modern web development' by a list of framework names, but the more useful definition is a set of defaults: rendering on the server where it improves performance, shipping less JavaScript to the browser, and treating accessibility as a baseline rather than an afterthought.

Server-first rendering approaches have made a comeback because they solve a real problem: applications that ship the minimum necessary JavaScript tend to load faster on real-world networks and devices, not just on a developer's fast laptop.

Type safety across the stack — using a single language and shared types between the client and server — has also become a practical default, catching a category of bugs before they ever reach a user.

The frameworks will keep changing. The underlying defaults — performance by default, accessibility by default, and maintainability over cleverness — are a more durable definition of 'modern'.
