Hi, I’m Fredrik Höglund! 👋 I’m a fullstack engineer with a passion for the web. I’m good at React, Node, performance, build tooling/DX, architecture, testing and much more.
I enjoy helping teams shine by teaching and mentoring and by removing hurdles and pain points. My superpower is finding simple abstractions for complex problems and I love tackling big challenges.
This full rewrite of the SSR docs for the upcoming v5 adds a lot of new content and splits everything into 4 guides that builds knowledge step-by-step: Performance & Request Waterfalls, Prefetching & Router Integration, Server Rendering & Hydration and Advanced Server Rendering.
Page navigation in the Next.js app router always happen in a transition. Hydrating data that already existed in the cache inside a transition would previously overwrite the cache immediately, instead of after the transition had committed.
Rollup by default removes directives like 'use client'. I made a plugin to preserve them so libraries using Rollup can still support React Server Components.
I saw this great question about uSES on Twitter, "Is useSyncExternalStore meant to support streaming SSR?" and I tried to explain how I think about it.
