Would be really great to see this one pushed through, this feature is very important to reduce Javascript load in front end, which will be a big boost to SEO

[Moncef12]

Any update on when this feature will be available?
We are using lazy hydration it will be a huge plus to not load the not needed bundles at first.

+1 for this - would speed out Vue/Nuxt applications greatly. Any updates on when somebody pushes the merge button?

[paulsharratt0]

C'mon guys @jeanphilippeds did all the hard work on this one, it shouldn't even be that hard a merge as it's an optional boolean, can we get this in soon?

@yyx990803 @posva @Akryum @Kingwl @LinusBorg Can we merge it please ? 🙏

@jeanphilippeds Did a very usefull work here !

[simplenotezy]

I wonder what's keeping us from merging this with latest release? How can I help?

[Darwex]

Guys, any news? how can we help? Sice google Web Vitals now scan more for unused code, this would help greatly.

[LinusBorg]

We currently focus all our efforts on bringing Vue 3 and its supor libs into RC stage.

Please understand that we currently have less bandwidth for Vue 2, and improvements such as this are currenty not a the very top of the list.

We will ge back to Vue 2 and do a round of bug fixes and improvements as soon as our bandwidth allows.

[simplenotezy]

@LinusBorg Fully understandable. Can't wait for vue 3. However, is this fix expected to hit Vue 3 as well?

[spacedawwwg]

Man, this is killing me waiting for this!

@jeanphilippeds, well done! Gutted it still hasn't made it's way in 7 months later

[fibigerg]

Hi, @LinusBorg, any progress on this? We are still waiting. It is even harder to get nice score after last PageSpeed Insights update.

[fibigerg]

Hi guys, there are still projects on Vue 2, can someone merge this, please? It really became a problem with new versions of Google Lighthouse.

[alexander-schneider]

can we merge this please?

[coffeeneed]

Is there any chance that this RP will be merged, as it has been over 3 years now.
