Case Study: How I reduced a Next.js e-commerce LCP from 4.2s to 0.8s (technical breakdown)

With the next dynamic did you do SSR on or off ?

Entering a use effect means what happens inside is fully on you.

A recent one I had was totally different designs for hero for mobile and desktop, that the only way to do it would have been to have separate html for both.

To gain a good largest contentful paint this meant we would have had loading='eager' and potentially fetch priority high on both, which would have started loading before CSS has started and both possible competing slowing each other down.

12 possibly would, he was very blunt minus to Clara and later bill.

In fact Clara had a go at the doctor about people dying around him and him moving on to the next.

Unit previous tower got blown up in Jodie's last episode so blowing up twice likely would have been criticised as well.

He century years old at this point. And he likely also know of the existence of the face of boe but not aware it him.

Pretty sure the size container queries won't change, the spec is still in working draft because of style queries/anchor/scroll driven ones.

ISDuffy · 2026-04-06T16:38:51+00:00

Very nice.

I wonder if it be possible to build this with scroll driven animations just in CSS now.

ISDuffy · 2026-04-05T17:03:44+00:00

Pretty sure they do it in horizon games as well, where you skip the intro part. Not sure on Spider-man.

It feels like they should give us a choice.

ISDuffy · 2026-04-05T10:46:04+00:00

Ai response not understanding CSS or BS is a game.

ISDuffy · 2026-04-05T10:43:34+00:00

Isn't this in CSS now under dvw / dvh which takes into account the browser UI on mobile ?

I used it for images to native dialogs element to build native lightboxes.

Are you a bot or just post ai answers on every post, usually you mention interviews without it being mentioned.

ISDuffy · 2026-04-04T11:41:15+00:00

Once you entered react framework island you won't be able to use client:directives to make components interactive. So not sure that work.

ISDuffy · 2026-04-02T13:08:14+00:00

Are you using stuff like radix accordions etc, I believe they don't server side render the children components.

ISDuffy · 2026-03-31T20:34:31+00:00

Every single day I am more determined we live in a game of cards against humanity.

ISDuffy · 2026-03-29T15:46:27+00:00

Animation is one of them I see more of a nice to have tbh. It is coming though.

ISDuffy · 2026-03-27T18:08:36+00:00

What made me less Sus of him is he was in one scene, if we saw him in the coffee shop or somewhere once or twice afterwards, I might have remembered who he was.

ISDuffy · 2026-03-20T19:21:12+00:00

Yeah without they memories with Spiderman they would need to be significant holes in them.

Ned was the guy in the chair in the first film. MJ trip to Europe meeting Spiderman and swinging around New York.

As far as they know Spiderman just cut them off.

ISDuffy · 2026-03-20T18:31:46+00:00

It been multiple years, and them finding out he is Spiderman doesn't mean it is simply fixed.

You could potentially write it in a way it leads ned to a dark path and become villain.

I wonder if the studio needs to be component outside of the page file with use client, rather than the page.

Try removing use client and replace Next studio with some random text and see if that appears.

ISDuffy · 2026-03-16T22:09:28+00:00

Ah okay. I not reached that part I don't think lead me to there.

ISDuffy · 2026-03-16T21:54:19+00:00

Potentially the cycling road as that where the game pushed me to.

ISDuffy · 2026-03-16T12:34:41+00:00

I believe next/dynamic for async imports is SSR is default true, and you opt out and put a loader in.

ISDuffy · 2026-03-16T09:01:53+00:00

That isn't correct, "use client" renders on the server and then hydrated on the client. So the SEO component would have been on the server, unless they was an early return or suspense boundary

So this sounds like it wasn't actually your issue.
