Completely forgot to plug my udemy course on Svelte 5 in the video. If you like my teaching style, you'll find it in the description though :)

This is a great video. Your explanation of the load function is fantastic, and the prefetch aroused my interest.

WHAT A AMAZING VIDEO!!! THIS IS WHAT I NEEDED. THANK YOU!!

Liked and subbed, love how you're just typing out what you're doing but with the code syntax. That's also how I learn new code concepts. Makes it so much easier to understand the HOW (skeleton structure), WHAT (typing out flow), WHEN (explanation of how structure and logic relate), WHERE (the low level code blocks). This gives us a nice and simple picture of how to structure it all and the end to end flow. <3

What if my links depends on the value of an input element, then i hover on the link and it calls the Load function, then i make a change to the input value and i hover on the link again. Will the Load function be called again?

[tejxsmore]

Such a good video. I needed this. Loved your explanation ❤

[bikerd]

I will buy your course i want to know does your course is all of in svelte 5 version?

[gageracer]

Great video. I would argue that in your case making it server side makes more sense as if the user has no internet, the client won't be able to fetch the thing anyway. Server side is always more secure and works good as much as client side fetch would.

Question: so if the code is running twice, are we calling any API (used in that page.ts) twice too? So are we wasting API calls/money?

[rogeriocf]

One thing about load function is we can not reuse that if we change some condition (p. Ex user has selected something)

[EliSpizzichino]

I think it's useful to make a video about set/getContext, state, cookies/sessions in connection with the Load function.

[D_bugit]

In your point of view... Would you opt for using load function always unless otherwise serverload Function is needed?

[EliSpizzichino]

I think you forgot to mention that if you structure your application's frontend with API endpoint that does the "secret"/backend stuff, you can then use page.ts's Load function to load data in. Am I correct?
