layout shift issue after switching to kubernetes and nginx ingress
I've just switched my site to kubernetes with a nginx ingress.
There's a weird layout shift thing.
Do you have any idea what could be causing this?

Hi @flav. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Based on the video you shared, I can see there's a layout shift issue when navigating between pages in your Nuxt application after deploying to Kubernetes with Nginx ingress.
This appears to be related to a known issue with Nuxt's page and layout transitions. The problem occurs because when transitioning between pages, especially when changing layouts, the scroll position is reset before the page transition is complete, causing a visible jump.
There are a few potential solutions:
1. Fix layout transitions: This issue has been addressed in Nuxt with a fix that allows proper scroll behavior after layout and page transitions. The problem was that Nuxt didn't have hooks to listen for when a layout changed or when it finished a transition, causing scroll issues when layouts changed. This PR fixed the issue.
2. Use nested routes instead of layouts: For pages that share common elements like a sidebar, you can use nested routes instead of multiple layouts:
This approach was suggested as a solution to a similar problem where someone wanted to use two layouts simultaneously Stack Overflow Post > Using two layouts simultaneously in Nuxt 3.
3. Use
setPageLayout
: You can dynamically change layouts using the setPageLayout
utility in route middleware:
Note that if you set the layout dynamically on the server side, you must do so before the layout is rendered to avoid hydration mismatches.
4. Adjust scroll behavior: You can try adding this code to your pages or layout to improve scroll behavior:
And add smooth scrolling CSS:
This was suggested as a solution for preventing scroll jumps on page reload in Nuxt 3 Stack Overflow Post > How to prevent the scroll from jumping to the top of the web page on Nuxt3 reload.
Make sure you're using the latest version of Nuxt, as several scroll and transition-related issues have been fixed in recent updates.

@kapa.ai on my video it's the old and the new website
Let me check the knowledge base for you again. One moment! :books:

I apologize for misunderstanding your video. You're showing a comparison between your old website and the new one after migrating to Kubernetes with Nginx ingress, and there's a layout shift issue in the new deployment.
Since this is a migration issue rather than just a Nuxt routing problem, there are several potential causes specific to the Kubernetes/Nginx deployment:
1. Layout transitions in production: Layout transitions can behave differently in production environments. There's a known issue with layout transitions in Nuxt 3 that affects scroll position on route changes, as documented in this GitHub issue.
2. Hydration mismatch: When moving to a new infrastructure, you might be experiencing hydration mismatches between server and client rendering. This happens when the HTML generated on the server differs from what's rendered on the client, causing layout shifts during hydration. This is a common issue in SSR applications like Nuxt when deployed to new environments.
3. Nginx configuration: Your Nginx ingress controller might need configuration adjustments. For example, it might be compressing responses differently or handling assets in a way that affects how quickly they load.
To troubleshoot this issue:
1. Check if you're using layout transitions and try disabling them temporarily to see if that resolves the issue.
2. Ensure your Nginx ingress is properly configured for Nuxt applications, particularly regarding caching headers and compression.
3. If you're using different Nuxt versions between environments, consider upgrading to the latest version which may have fixes for layout transition issues.
4. Try using a blank layout for pages where you're seeing the shift, as suggested in this Stack Overflow answer.
If the issue persists, you might need to examine network requests, rendering timing, and CSS loading patterns between your old and new environments to identify the specific differences causing the layout shift.
