In general Next.js has so many layers of abstraction that 99.9999% of projects don't need. And the ones that do are probably better off building a bespoke solution from lower level parts.
Next.js is easily the worst technology I've ever used.
Pocketbase was the ONLY good thing about this journey. Everything else sucked just so terribly.
Infinite complexity everywhere, breaking changes CONSTANTLY, impenetrable documentation everywhere.
It is just so, so awful. If we rewound the last five years of FE trends and instead focused on teaching the stuff that existed at the time properly, we'd be in a much better position.
I've also built a very complex React frontend (few thousand users, pretty heavy visual computation required in many places). And while I don't particularly like React either, Next.js was even worse.
And lastly, built a CMS in Go, with vanilla JS. And while the DX sometimes feels lacking, I just can't help but feel that I actually know wtf is going to happen when I do something. Why is that so hard?
In React and Next.js I am STILL, AFTER SIX YEARS constantly guessing what might happen. Yes, I can fix just about anything these frameworks throw at me, thanks to all the experience I've gathered about their quirks, but it all just feels to messy and badly designed.
In Go, the last time I guessed what might happen was in the first six months of learning it. No surprises since. Codebases from years ago are still rock-solid.
Why can't we do this at the frontend, goddammit?
Canvas instead of DOM -> :(
EDIT: Gave it another try and more issues appear, within seconds of using. The left side has a rendering bug where the selected areas are cut off sometimes, ctrl+zoom does not zoom the page as it does on all normal websites. I can still zoom via menu. Middle mouse open link in new tab doesn't work. Z layer bugs everywhere. I expect more the longer I'd look.
The “static preview” it shows while it loads (for like 10-15 seconds!) is so much smoother and nicer to scroll around than the actual thing. On mobile, every third scroll attempt actually opens the right click context menu. It’s a stuttering mess on my high refresh rate phone. Nobody should ever make websites like this.
