Funny how they were so proud of the heavy cache first approach and now they've done a full 180

[@hamedbahram]

I actually like the cache first default so I don't have to worry about optimization. We'd have to see how this evolves over time.

[@MegaRandompoo]

@@hamedbahram I don’t mind it either honestly, I think they should have just left it because now we have to unlearn everything 🙃

[@jfhandfield]

Nice informative video. Thank you again for your time!

[@hamedbahram]

My pleasure!

[@ahteshamakram8078]

@hamed bahram you told in your Revalidation in NextJs vedio that you will publish a vedio about NextJS Catching in detail . Have you uploaded that vedio ?

[@hamedbahram]

Not yet, but will do sure after these new updates in version 15.

I'm a fan of Next but it drives me mad when you learn how it all works, for the team to decide to change it and you need to relearn concepts, AGAIN

[@hamedbahram]

There won't be much change in version 15 other than the addition of React compiler and defaulting to dynamic behaviour when it comes to caching.

[@collinsk8754]

[@hamedbahram]

My pleasure!

Hey 👋🏼

[@bakertrevis]

Why does all of your videos have to be 20+ minutes?

[@hamedbahram]

How long would be better?

[@shaikhfaisal2423]

​@@hamedbahramIt's already good. You don't have to change the duration.

[@armaandhanji2112]

The length of the video isn't important at all, it's the quality that matters, and this channel always provides top quality content.
