Im actually glad svelte is introducing runes,cause its kind of made it difficult to get which variable is reactive or not,the progress is worthwhile 💯
Love the Svecosystem plug 🔌 great video man!
hello sir decaprio!
thank you! 😄
@@JoyofCodeDev not you it was huntbyte he actually lookalike 🤣🤣
Svelte 5 is really exciting, hopefully it launches soon!
The best and most comprehensive overview of reactivity in svelte as of now. Good job and thank you!
I use react at work, but your videos + svelte's runes introduction (fantasy nerd here) made me delve into svelte whenever I have some spare time. kidas brate!
This is much clearer than the official documentation.
the preview docs for Svelte 5 are temporary and there's going to be official documentation and the tutorial when it's released
From the intro, you can perceive this video is going to be especial
Bro your animations are on a new level 👏👏👏
He uses Svelte to create presentation slides with animations
You can see how he does it in his latest video
Great production quality! Thanks for leading the Svelte 5 transition!
Amazing video as always! I really love your content.
I've noticed there isn't a good video explaining all the i18n options for sveltekit available and comparing them. It could be a good idea for a future video and I'm sure that your audience would be very interested to it.
How beautiful is that my friend. I'll remember always you from that 😀
I'm so excited for Svelte 5 😍.
Svelte is getting every day even better, thank you for such great content!
Amazing explanation video.
It makes a svelte version upgrade much easier with all of these examples!
Thank you 🙏
Showing the generated code was dope. Well done
It is a great video, clear and good
comparing examples. And the slide change animation is also top.
Looks like MVC is back on the menu boys! Having written a diagram app using Svelte 3 and interactive components derived from class states, Runes look like a dream come true.
You're amazing, the best svelte advocate
Thank you!
Love your materials, they are contains a very useful information, thank you 👍
This was great, thank you!
14:29 is perfect
i smell svelte 5 is near !!!
88% complete
@@Eloii_Xia Not exactly.
@@mohabedr5030it is, go check their GitHubilestones
@@mohabedr5030 why not?
I love your content, I am about to start getting into Svelte and am super excited, this looks so much easier than other frameworks.
You should start exporting in 4k. Even if you recorded in 1080 it increases the bitrate and makes it look much better. Your videos are beautiful they deserve max bitrate
I might try it out
amazing video!
Good explanation.
Great overview. I've spent a lot of hours on svelte and am quite comfortable with the quirks of the current version. I find it more kinda hard to wrap my head around what magic happens with $state. Especially the props thing doesn't seem super intuitive. I'm sure I'll get used to it but saying it's "easier" or clearer kinda feels like a lie.
I think `let count = 0` is more magic than `let count = $state(0)` which works the same inside and outside Svelte components - what makes Svelte special isn't `let count = 0` but `=` for reactive assignments.
I missed you my friend :)
Thanks!
thank you! 🙏
i love svelte, i am always afraid to dedicate myself to learn it fully because i feel i can't get a job with it, but i really enjoy so much developing in svelte.
listen to your heart
@@JoyofCodeDev Oh, sovereign joy of code, no matter how metaphorical or cheesy it may seem, I was waiting with the greatest subtlety for any response from you, and since you have heard this sentence, I must enjoy coding what I love. Furthermore, if UX and UI are for the user, from now on I proclaim DX & DI: Developer Experience & Developer Interface :)
however, thanks a lot
subbed!
I am just waiting for melt-ui to be runified. It would be a pain to start coding with its stores paradigm and then change to runes. The refactoring required is akin to rewriting the client code from scratch.
What a beauty.
Lmao I fucking lost it at 14:30 😂 nice video!
Please is there like a PDF document that one can learn about svelte 5 ... i really loved Real-World Svelte: Supercharge your apps with Svelte 4 by mastering advanced web development concepts

Tan Li Hau cant we have something like that for svelte 5
Hi, I have a question. Could I use a svelte store value, eg. $name, inside a svelte form action?
Great video, you are awesome !
How do you make these code snippets transition ? Which tools are you using to make your videos ?
I use Animotion which is something I made and I'm working on the video for it next
great
I am somewhat concerned about using typescript on my svelte 5 project. Is it any better for bigger projects or just pure coding overhead?
Great vid, now we need Material UI for svelte, not the trash its out there (outdated)(non-svelte5)
Before I learned Svelte, I used React, then SolidJS. When I learned Svelte 3, in my opinion, it was simpler and it was the best language and framework.
In my opinion, Runes will destroy this framework, something that was simple now start going to React again. The only difference between SolidJS and Svelte now is where you have XML and where JS.
Svelte optimizes for vibes
I am confuse. What happen to stores in Svelte5?
I have a store and could not figure out how to refactor to used Svelte5
stores are deprecated. you can just declare a variable as a state rune and pass it as a prop everywhere needed
@@francoisbouchet9907 Stores are not deprecated, they will work exactly like in Svelte 3 & 4. But in most scenarios they can be rewritten to signals.
@@francoisbouchet9907I’ve found that having side effects similar to subscribing to a store is a bit rough (outside of svelte components). Runes don’t really replace stores imo.
I don't really get the derived rune. Isn't anything you do with state by definition 'derived'? Count is state, so why do I have to say count +1 is derived? Obviously it must be..
Because you want the derived variable to be reactive too in the places you use it.
@@sledgex9 hm yeah I need to read more about it. It just seems odd to me that the state rune couldn't just do it all. Ie the very presence of state in any other function or statement would simply tell the compiler that this line of code must change along with the state it references.
the derived rune is for state that depends on another rune. in your example, it's derived so that the derived value is recomputed when count changes
@@adamjennings4797 it's not reactive with in , it's only reactive to ui parts
just think this ->
count = count +1 create a infinte loop
the interesting part about derived is memoization and you can use `$derived.by` for more complex things but for example `count * 2` doesn't have to be derived and you can use an expression or regular function in your template
svelte 5 is not yet official in sveltekit 2 right? still have a lot of time to practice runes
you can pick Svelte 5 from the options and it's backwards compatible so it's easy to transition
Svelte 5 is awesome, but if you're using any external Svelte libraries in your project, WAIT until it's fully supported before updating. Trust me 😭
Yea, it's a major version update, we shouldn't just update older version to new...
make your own library 🧠
@@JoyofCodeDev can you make a video about making svelte 5 libs ?
Why is the compression so blocky and ugly? Even at 1080p
UA-cam compression works in mysterious ways
@@JoyofCodeDev its very sad. Really good video otherwise. Im guessing its because of the dark nature of the video. These compression strategies usually compress many dark values together because its more difficult to distinguish between them. Next time i would recommend you upload in a higher resolution like 4k or use 30fps instead of 60
it just takes time 😄
Svelte 4 was the reason why I switched from React. Svelte 5 is the reason why I quit on Svelte!
Was completely thrown off by the waifu voice 😂😂😂😂
So svelte discovered redux? 😅
I think you're lost
@@JoyofCodeDev no worries, everone has some skill issues
so its basically vuejs now?
I would say Vue is trying to be more like Svelte if you look at Vue Vapor
@@JoyofCodeDev mithril was where its at.. they should have developed more in that direction
🤔 at this point, anyone can be frontend dev in a week...
the code too small
svelte is for lazy people like me who dont wanna dive into overcomplicated react bullshit and its stupidass ecosystem. if i have to use this effect and state fake ass react shit, i will use react directly
why in svelte 5 using two method, on: and onclick,.... Not simple, so complicated, svelte becoming sh*t
you can use both because Svelte 5 is backwards compatible making it easy to transition but it's going to be deprecated in a future version
Svelte 5 == Almost Solid.js but with $ prepended so they can continue to implement a compiler instead of letting you use hooks like useSignal. In my opinion Solid.js is superior, simpler, more elegant, not because it adds terser syntax, but simply because it achieves the same things using just the programming language itself. And it's also my opinion that learning the language is the biggest problem in the FE world. Too many people learn JS by learning React or some other framework because that's what they want to write all day, but that's not what being a programmer is. /endrant
Nope. Solid doesnt reach what Svelte can reach. Solid is just react with signals.
Svelte is quite different, in the big picture it shows how simplicity at its finest can improve your day to day.
I like abstractions. I'm not a hardcore developer, just a hobbyist, so having some opinionated magic is great. No disrespect to solid, is a great framework, but it didn't clicked for me although it was on top of my list. To be honest, if not for some great svelte edutainers I would be using solid, or maybe vue.
I think you misunderstood completely how Svelte3/4 worked and how Svelte 5 it does. Just because Svelte5 is using Signals ( like Vue ) you think that is almost Solid. This is like the people who thinks that Svelte5 looks like React because has $effect(). Please, try to learn and read deeper: devs are responsible at some point about companies decisions in the future regarding tech stack to use.
Too many gotchas with the API == React.
ignorance is bliss
If you don't use these libraries with your side-project as they would make your development easy, don't ever use them. They are dead for professiononal web development and you wouldn't learn anything about anything because you'd take everything as granted, React is popular because you do everything, it's plain javascript that poops html, thats it
I hope I'm misunderstanding your sense of humor, but I personally prefer my development to be easy rather than hard. As for not learning anything, how is that possible? After all, "these libraries" are open-source, and the code is there to be examined and learned from. And furthermore, I truly believe you need to learn, and learn well, how to use them despite their (apparent) simplicity.
@@paolo-e-basta yes, a javascript junior developer would go through source codes. React is not hard, nor Next, they are tools to make something work, if this something is too much for your project, of course don't use it, but then don't talk about it either.
@@dogakoorkmazSvelte is also a “[tool] to make something work.” So what’s your point? Ironically, the layout of svelte is closer to vanilla html/js/css than something like react/jsx; if anything, a beginner learning svelte will learn more about vanilla html/js/css vs one learning react.
@@JJCUBER React is not there to make you learn html, I was talking about normal people who are not 5 years old and jump to a framework without knowing basic concepts of frontend. You too know that frameworks like Vue and Svelte is out there because PHP developers didn't want to learn frontend, these are frameworks that gives everything out-of-box and can make basic projects that are mostly/strictly bound to some backend. Not so great for a student that wants to know how a real application should work and the inner concepts of a frontend system, they are great if you want "magic" with a one click though.
