Just upgraded a couple of projects to Nextjs 10 with support of React 17. Two of those features got my attention: Built-in Image Component and Internationalized Routing. One of my projects did have needs for these two. What I did was made custom component to handle image loading and appearance. For lan switch, I made a folder called “en” and put all pages in it. Put switch button on nav bar. Those work just well except image optimization. And finally they have “Automatic Resolving of href” for “next/link”. Always like upgrades, and Go Nextjs!
