The way these concepts are explained (like the content and the wording) together with the matching visualizations makes this one of the best "dev tutorials" I have ever seen. Great job!

I like how Next is also focusing on explaining their concepts themselves instead of throwing a bunch of features with a mediocre documentation, that's a good explanation, keep it up.

[@MuhammadHaseebAhmed]

ngl even Lee Robinson was not able to deliver concepts of PPR as you did . amazing !

[@Delba]

We work together :P He gave feedback that made this better.

[@codeChuck]

It is funny how Theo explains the same concepts, but without animations! With visuals it is even better! Cool stuff! Keep up the quality! Thanks for video!

[@Delba]

We tackle the same problems from different angles.

[@nayeemxtreme]

Awesome video!

[@manmandangdang]

That was fantastic! I hit subscribe right after watching it.

[@Delba]

Thanks, welcome!

[@thefullstackproject]

I wonder how you create these awsome visualizations. Great work!!

[@Delba]

Thanks, I use Remotion.

[@slyracoon23]

Do you do any post editing software as well?

[@tradfluteman]

This is the best explanation I have seen of these rendering models, by a lot, but I still think two misconceptions are possible, especially for people with self-hosted apps: 1. You do *not* need the Edge or Vercel, or even a CDN, to take advantage of PPR. The Next Route Cache will serve your static assets. 2. PPR is only about speed, not about cost. Users will see the cached static parts of your app first, but those parts will still eventually re-render on every request, so that the dynamic parts re-render also. Next cannot break your app apart, unless (maybe) you're using parallel routes, so it needs to run the whole "rendering engine" of your page just to get the dynamic outputs, with all the cost incurred. This means there are still big advantages to using pages that "partially render" with fully static content on the server and then complete the rendering, with personalized data fetching, on the client. Next even confusingly tries to force you to do data fetching with request-based data on the client, in layout components, for this exact reason. Otherwise all your pages would become dynamic, even if served with PPR.

[@Delba]

Thank you! In general, this video is about the vision of Partial Prerendering that we're building towards, not about its behavior during alpha.

[@hectondomingos3264]

Well made video.

[@rawallon]

Excelente video, foi bem completo sem entrar em detalhes tecnicos, Vou mandar na minha empresa pra todos verem!

[@Delba]

Obrigada, espero que ajude!

Good stuff.

[@VadimTi320]

What’s great about next.js is that you don’t really need to know all of this for it to work, it’s just automatically prerenders what it can

[@codewithidan]

I love the visualization and explanation! How have you did these visualizations? looks awesome

[@Delba]

Thank you, I use Remotion.

[@Xaphirre]

Beautiful

[@jordinodejs3291]
