[@IzzyIkigai]

Honestly, I think React is just a good example for how swathes of the dev community have become slowly boiled frogs. Like what kind of unpaid intern at Facebook thought HTML syntax in the middle of javascript code was a good idea?? I mean, I've been out of the loop for frontend for a few years and came back to shit like that. Looked at what's hot and p much the only thing that didn't make me want to chug up my coffee like i'm a pressure washer was svelte... Everything else just looks like people threw together "what we learned not to do" examples..

[@ebmpinyuri]

I like the fact that Rich Harris does not pretend to know everything especially even things he has made himself lmao

[@kevinkkirimii]

It's called maturity.

[@wadecodez]

he's not pretending or humble. he just works with a lot of code. too much for any one person to memorize.

[@Knigh7z]

You can't remember everything either

[@toothuncommon0]

pretty sure he was referring to the inner workings of the tutorial "framework" - much of which he did not personally author

​@@wadecodez plenty of people out there who will not admit that they don't know/ remember something. I give him a bit of credit

ever since i started using Svelte, man nothing else can beat its simple way of solving annoying repoetitive things when building websites, add on that speed and the fact that it's JS inside HTML, super sweet

[@fitsbachinteractive]

Imagine writing JSX/TSX thinking it's a smooth experience and being one of those that picked "heard about it, not interested" for Svelte/SvelteKit in the StateOfJs annual survey.

Comic Sans MS is a proprietary typeface owned by Microsoft and requires a license for commercial use. It is pre-installed on Windows and macOS but not on Android, iOS or Linux.

[@metatronicx]

That part is so true 19:36. I've had a hard time integrating third party libraries in other frameworks especially in Next.js. But it was so easy and straightforward in SvelteKit. SvelteKit is just an amazingly easy framework and I really really like that.

[@DEVDerr]

Bad that you didn't touch Svelte Stores and transitions. For me, they're the best Svelte features. Stores especially, because they finally nail the global state part. And it does it so well that I started to think why the hell stores in React had to be so absurdly complex

[@skl9942]

Exactly what I was thinking!

[@SpaceChicken]

Same. Transitions were enough for me, store is so insanely useful. Wonderful features.

[@baka_baca]

Stores are definitely one of my favorite features too! The only things that have come close are Zustand and Pinia, both really good options but neither of which gives quite the same feeling of simplicity and elegance as Svelte stores. I've never had so little trouble making as many stores as I wanted, each being easily customizable to any degree, and then having everything just plain work even though I had just learned it all ! Svelte still strikes me as something truly special in a field crowded with options.

[@mfpears]

Stores nail state management like jQuery nails the DOM.

[@Pavel-wj7gy]

Stores in react are so absurdly verbose that they may cost you a job.

[@NatoBoram]

The best feature is definitely the {#await} keyword. You can start a call, assign the promise somewhere, and have the UI automatically handle all possible states of the promise in a declarative way.

[@heitorlopes9914]

Earned my like after just hanging out by the fireplace together! Amazing vids, Primeagen!

[@DamonMedekMusic]

I've used Svelte daily for over a year and I still love it. Extremely minimal and straightforward. Stores are great. Docs are great. My hardest challenge was using the backend as a rest api as a internal database for forms but once I figured that out theres really nothing it can't do so far.

[@adamlul]

Rich is awesome. Love watching his interviews.

[@BrandonAaskov]

I loved Rich Harris for his philosophy and approach to svelte and sveltekit but this is the first time I’m hearing and seeing him. Now I’m even more impressed. His humility is fantastic to see.

[@nullbeyondo]

If you're new to Svelte and/or coming from React, this video is literally a complete tutorial and also entertaining with actual questions that you might have Wow. You don't need to go anywhere else. I think it was more accurate to rename the title to "Svelte" instead of "SvelteKit" cause it doesn't really teach about SvelteKit or the concept of layouts, routes, and adapters.

[@cre8ive65]

Been running SvelteKit in prod since the early beta. Dealing with the breaking changes as it matured to full release was well worth it, and I would gladly make that same choice again.

[@nullbeyondo]

I'm glad they did that stream. Rich Harris seems like a cool guy and this video with feedback from ThePrimeagen would help improve Svelte more.

[@nacs]

Rich Harris is amazing. Insanely smart but more importantly -- relatable and humble.

[@javierflores09]

I was just doing the svelte tutorial yesterday myself, and the error making it lose focus drove me nuts too. Other than that, it does seem like a nice introduction to Svelte. Edit: Also, what I think Rich Harris meant at 47:16 is that you could just have done: $: validated = name == "Hello world"; and it'd have worked

[@ThePrimeTimeagen]

yeah! it was very fun!

3:30 Harris: I don't love doing it in front of an audience of 800 people The people: 54k

gotem

[@stijndcl]

What you said about halfway, about Rust standard library types implementing your own traits but only when you import it, is also how it works in Kotlin (extension functions). For example, in Android you can import an extension function on the base "Int" type for sizing (using px or dp or whatever unit), so you can write things like 23.dp.

[@danvilela]

Bro the rust part 🤣🤣🤣🤣 Caught Rich completely off guard.

[@joaodiasconde]

Svelte seems amazing, so simple, so effective.

[@darkarie]

[@poolkrooni]

What Rich meant for the validated function was: $: validated = name === 'hello world' and then in the template part you could simply have {#if validated}

[@asdfghyter]

[@tthiagolino8]

Great conversation, especially the part where you broke the New York Times paywall It's just a shame you didn't get to address stores and transitions/animations during the conversation, they are in my opinion the best part of Svelte (some frameworks even have apis for state management but none using an open contract approach like Svelte)

[@g1uh4]

This is a good way to learn Svelte. No bs, straight to the point.

[@stashladki2594]

The funniest thing to me is that all the concepts Prime reacts "wow!!" to, aren't all particularly new and most got introduced by Angular long time ago which is considered to be hated out of this world by the same people :D

[@mosesnandi]

AngularJS?

[@user-hk3ej4hk7m]

On the little intermission about rust traits: that's just syntax sugar for function overloads on return types. Julia, Haskell and many other functional languages allow you to define custom operators on types to do the same thing, or even just using functions, there's nothing special about the dot operator. For some reason rust takes this roundabout overly explicit road just to do function overload on return types.

[@kokizzu]

framework/compiler i love the most past 4 years XD

[@cubondemais]

watching this in 2024 after Svelte 5 entered release candidates stage. At 35:25 ThePrimeagen complains about not being able to mutate objects and just letting the garbage collector run wild and I'm thinking that he would be really happy to know that, in Svelte 5, state will be fully deeply reactive with mutations, not only assignments.

[@TheDanVail]

Ah shit I’ve been wanting to learn Svelte(Kit) let’s go daddy

[@badunius_code]

48:10 it feels like using a function here is sub-optimal, because it's going to re-render the block on every name change, whereas we only need to re-render on validation result change `$: validated = name == "whatever" // this reacts to the name changes ... {#if validated} // this reacts to the validation result changes`

[@AdowTatep]

Talking about the rust part. Just because I'm interested in learning rust, when he shows the contains_range method, isn't it the same as c# extension methods? The difference being that it's scoped to that file though, like he mentioned. Oh yeah i just saw it's called extension traits (i know that rust has other stuff other than just that, too)

[@vellankiindeevar5530]

man you youtubers are so lucky , you get to learn from who build sveltekit

[@voidmind]

You can tell whoever coded this demo app did it in a Windows centric (Comic sans) and Chrome centric way (I wouldn't be surprised that all the issue Primagen found go away if you use Chrome).

[@dmitriyobidin6049]

29:35 So it's like extension of some sort(swift have those, for example), but just because it's in rust it's automatically magical?

[@7heMech]

Now I wanna write something in Svelte.

[@tyunpeters3170]

This was more of a Svelte lesson and not SvelteKit, since there was no data loading or retrieval

[@dmitriyobidin6049]

My only question to svelte is - does it have any limitations? Is there anything that we can build with react/angular/vue, that wouldn't be able to build with svelte?

[@moon_bandage]

Not with the purely view related part. So svelte vs react you would be able to build the same things, because they fill the same gap: reactivity between JS and the DOM it's all they do. It's a different story for SveleKit and Next. Next might be more advanced

[@shirecoding2440]

this looks really like webcomponents, wondering is it using webcomponents underneath?

[@kaibe5241]

One thing I REALLY love in Svelte, is two-way data binding. This is something that Vue takes a really strong stance on, not allowing it - which has been a huge source of frustration for me, because it means you have to use a store or something, which actually complicates your code. Sometimes components are meant to work together as part of a single system, where two-way data binding makes much more sense. The fact that Svelte supports this, meant I moved away from Vue entirely.

[@garretmh]

Is it different than v-model in Vue? It sounded exactly the same

[@tehsimo]

is the rust thing at 30:51 the same as an extension method in C#?

[@TheStickofWar]

pretty much, Prime knows a lot about the things he uses but he doesn't know a lot about the whole landscape (which is fair, it's a lot of stuff and you only spend your energy on what you need to care about or are interested in). But it isn't unique to Rust

[@pengain4]

[@FredoCorleone]

Well, the part about reactivity with reassignment is better in Angular as it's track objects by default you can have it refresh even if you mutate the same object. Obviously it's more expensive and infact you can disable with OnPush something (I don't remember) but still it's very beginner friendly. And... Unless you do really stupid things you can track A LOT of objects in the same view.

[@PeterBernardin]

Oh my lord I was pulling my hair out when you weren't getting Rich's syntax description at 47:00 ... I mean he could have just said use the ternary operator, but still!!! You had to turn this: $: { if (name == "hello world") { validated = true } else { validated = false } } Into this: $: validated = name === "hello world"

Should you ever be able to get Svelte propperly running in Vim, please make a tutorial. Your "0 to LSP" Video was one of the reasons, why I started to work with Vim (I'm using NvChad at the moment) Got Svelte set up far enough, so that all the highlighting works propperly, but the Intellisense is mostly broken. VSCode and PHPStorm/WebStorm are fine but it just does not feel the same, even with their respective Vim-Plugin installed. 😥

I also followed his 0 to LSP, then tried switching to NVChad but I was already used to the defaults and NVChad changes so much it pissed me off. So I'm back to Prime's config 😂
