Next.js

Tried Next.js on one project at the setup stage. What wins you over is how much time it saves at the start compared to bare Webpack: no writing and fumbling toward a working combination of configs and initializations. Then again, we already have our hard-earned presets, so that advantage turned out to be moot — while losing control over the build itself was something we got cold feet about.

Verdict: project builds stay on Webpack, and I'm filing Next.js away as a tool for quick prototyping, sketches, and research experiments.
