Svelte Hot Takes - Reacting To Web Hot Takes from Rich Harris

[@allesarfint]

I feel Theo didn't understood the "Sites should work without JS" take, it's not about making the web fully functional without javascript, is about getting a good enough experience when it is not available, and frameworks should enable devs to do that.

[@Divisibly9610]

Yeah, as an example, your calendar could just show just a list of your daily appointments when JS isn't available.

[@Ironication]

Basically progressive enhancement should be a focus for modern JS frameworks. I think not a whole lot of people use this way of building sites because it requires extra research and work, plus everything else that needs to be accounted for (i18n, responsivity, business reqs). Would be neat to have a curated list of good practices in one place for easy reference until some support trickles in from framework builders.

[@b0nyb0y31]

"Graceful degradation" is something I've heard people used before. Now that SPA has become so pervasive, the idea kinda got shoved away.

[@dovh49]

I built HTMF, similar to HTMX but with forms first so it makes it easy to build progressively enhanced websites with minimal JS on the front end. It can be even offline completely and a site that works with no JS. Forms for the win!

[@Leto2ndAtreides]

Not sure it's as worth it today as it once was. Plus, you can just cache the javascript...

[@adrianjdelgado]

I think most of Theo's disagreements are misguided. The talk is presented from the point of view of a tool maker. Rich is not saying that developers should carry the burden, instead, the frameworks and tooling should do the heavy lifting.

[@MarthinusBosman]

Exactly, datetime stuff suck, because cause the browser or tooling isn't doing it for me as it should.

[@OurDivineKing]

Such a well needed talk! Rich has the ear of the industry and for a good reason.

[@Hwyadylaw]

"Most sites should work without JavaScript" is something I agree strongly with. I think "most" does some heavy lifting here, because even if most what Theo does can't work without client-side JavaScript, most of what is deployed on the web *can*. Even if I don't disable JS, I have to deal with the consequences of the JS requirement regularly. The number of times in the past month that broken JS has made a site inaccessible without me having to do DOM manipulation or patch the broken script isn't high, but it's ridiculous that it's more than twice. 18:50 Rich isn't saying we should get rid of JS, he's saying removing the JS shouldn't break everything. 14:10 I think Rich's message is basically "we should ensure that people *don't* have to work with datetime themselves"

[@DiegoBM]

I love this because you can see both Svelte and RSC approach hand in hand. I'd love to see a Rich's react video to Theo talking about RSC to have the complete circle

[@Divisibly9610]

Just a note, I see a common theme here he makes an opinion and you immediately decide to agree or disagree. I feel it's generally better to let someone state their position before we decide on which side of the argument we fall.

[@mileselam641]

Yes, I don't like TailWind, and I don't like React. This is not because I think I'm a CSS genius. It's because I'm old enough to remember . We've lost sight of why CSS was created: that styling in markup is convenient but inflexible. In addition, React has no CSS styling isolation between components. There was bleed through. TailWind absolutely helped with that. But once you're not using React, using a framework that scopes CSS to the component (like Svelte does), that need for TailWind to solve that problem evaporates along with the problem. If TailWind were a Sass mixin or used CSS variables like Open Props, I'd have no problem with it. It's not the idea of TailWind-collections of related, pre-made, consistent styles-that bothers me. The implementation when viewed through the lens of React's scoping deficiencies even raises it to truly exceptional engineering. I accept good engineering overcoming bad decisions, but I struggle with accepting the bad decisions as part of good engineering. (And I fully acknowledge that they were not objectively bad decisions a decade ago. 20/20 hindsight and all that.)

[@riolly]

We are so thankful to have an awesome journalist on the JS land.

[@ISKLEMMI]

A thoughtful response to Rich's thoughtful talk! Thanks for sharing this. 26:51 - "React's whole thing is it's just JavaScript." React folks often say this. This isn't true about any front-end framework, but it means React (and others) are so good that they *feel* like just JavaScript. Most obviously, JSX is widely used and is objectively not JavaScript. It's not in the standard or in any JS implementation. (Linters like TypeScript support it for obvious reasons.) Solid, Vue, React, Svelte, etc. also all need compilers for their abstractions to work and add hidden control flow to do many things such as automatically re-rendering your components when data changes. (Full-stack frameworks are a whole other can of worms that you and Rich already opened in your respective videos. lol) There's a lot more, but this comment is long enough. 42:08 - You *do* have to call signals on props as a function. The code on the slide would only work if those components were passed the return value of the signal

[@TayambaMwanza]

The problem is that React devs don't say, "it feels like its just js", they say "it's just JS", I think the former statement is more acceptable and should be what they say rather.

[@mormantu8561]

Calling React "just javascript" is quite the stretch in my opinion. I know React but I put it off many times because of all the extra syntax and rules. The most obvious being the "useState" hook instead of creating and mutating a variable.

[@mikle1404]

I'm part of the sliver of your Tailwind Venn that isn't complaining based on React performance. Tailwind sucks because it's not vanilla CSS.

[@DrClocktopus1]

Has CSS ever been the problem when it comes to performance? Tailwind or not is a matter of DX taste imo - personally I prefer styled components or even just css modules - anything that will let you write actual css

[@docmars]

I use Tailwind with Styled Components using Twin.Macro -- never happier!

[@paragateoslo]

I feel Tailwind mostly solves issues people had with styled components, which again solved issues people had with global css that again was already solved with css modules. I have never heard any arguments of either styled components or tailwind that css modules dont already solve. The only thing Tailwind has going for it is a good set of default design tokens. But why not just copy those and use them in vanilla css and css modules?

I'm not anti react. It's cool. But I am a svelte lover and oh man, I can still admire react, but I won't touch it if I don't have to now that I know how simple, elegant, and concise web development can be.

[@nowheremap]

i don't think sveltekit users are typically all that aware of performance. svelte was always targeted to casual programmers to an extent; it started as a tool for data visualization professionals to build widgets fast without having to learn much on top of basic javascript.

[@Mitsunee_]

now I require that rant on the datetime video. I've been working on and maintaing an event timers site for a videogame for almost 4 years now and there are so many nasty pitfalls to step in; I'd love to hear more people their takes on this stuff.

[@JochiKahn]

I have used a JavaScript blocker for the last 10 years, it works on a white list. From my experience most sites do work without any JavaScript, but it feels like 90s internet. Unless it's super important, I won't even bother with sites that don't load without allowing off-site JavaScript.

[@erics2133]

Given your take on how Svelte made = "magical" I'm assuming you approve of the reactivity changes coming in Svelte 5? Just curious, I'm in favor of it as it makes it more explicit but still easy to work with.

[@ryanquinn1257]

I thought a date picker would be a simple component I could make months back as a newbie. Hell no.

[@nephis_2006]

The take on JS being event driven and ui is state driven is terrifying

[@brian-mcbride]

I just don't think Javascript is evil. Maybe we need better ways to bundle/load/etc and even then things have come along so far. The argument "ever tried to use an app on the subway when connection drops and your JS didn't load?" Ok, you have no connection. You won't be making new calendar appointments either. Remember the PWA idea? Were the site/app you use is cached so when you go to use your app it works offline first? We have chased the goal of "first paint" and "time to interactive" on the very first user at the expense of the tooling around repeat users. Maybe you are a news site, that first visitor is more important. Or you have a calendar app, I'd lean into the repeat user experience.

[@bartech101]

If you lose connectivity your app without javascript won't work either. Without js you need a roundtrip to the server, so if you have connectivity you can get js in the first place.

[@Holobrine]

Navigating the client server divide is the next frontier, eh? My take is be selective about what needs the server at all, but when you do go to the server, make it do most of the work. What this means is, if you don’t need to persist state, stay in the client. If you do, make the server do all the validation and get your response in hypermedia form, ready to just display somewhere on the page. All this to say, htmx and hateoas is the answer. One bit of nuance to generalize a bit better: The computation location should depend on the lifetime of the state. If it’s ephemeral, do it in the client. If it’s shared between a only few users (e.g. Google docs editing), do it on an edge machine close to them. If it’s forever, do it on the main server(s), or even a big distributed back end.

[@astartup]

I do live coding and I do like having less stuff on the screen, but I'm never giving up all my monitors. I use a 4K monitor for my living coding and I zoom in to 1/4 of the screen so you still get a 1080p stream, so I have the huge fonts in OBS, but I make the Explorer 1/2 of the screen, and the console is 1/4 and code with is 1/4, both on the right-hand side. I have an ultra-wide monitor that I use for OBS and I can add an extra browser window. I use also a dedicated 13.3" 1080p monitor for an extra desktop. This allows me to quickly switch between the browser that the live-stream viewers can seek I also have one more 13.3" 1080p monitor that is for utility. I just use them for quick reference, or I'll have a tutorial video on them. I've got a badass RPC library called Script2 that is a baller and better than tRPC. You have to have RPCs to do most multi-threaded applications. HTTP is essentially a RPC protocol, so is GraphQL.

No, React websites do suck. Yes, some websites need React because of a lot of state. But most don't. .NET Rocks website started using React and the user experience went way down. The thing is most websites a static page with a little interactivity is OK. Other websites something like HTMX works fine.Others, that need a lot of interactivity on the front end, React could be a smart choice. Yes, ads on web pages suck too and can overshadow the problem of SPAs for sites that don't need SPAs.

I was young and needed the JS :P

[@EthanStandel]

In the Solid example, the reason you don't call count as a function is that props is always a reactive object so accessing the count property is the same as calling a signal accessor function. The solution is that doubleCount needs to be a function, which I think makes more sense _unless_ you're React brained. Especially once you're signal-brained, the concept that all dynamically updating state should be wrapped within a function is actually super sensible. I recently converted a React library to be a Solid library and all that it took was identifying each piece of unique input state and requiring that it be a signal accessor and that any subsequently calculated values just became functions rather than values. After that it was just convertilng useEffect to createEffect and getting rid of the now unnecessary dependency arrays. I think it's really dumb that this example got included with "implicit DSLs" and it's a sign of major React-🧠 which is surprising to see from Rich.

[@vipero07]

29:42 I find the whole "it's just JS" thing funny... JSX is not just JS. It is under the hood, but it isn't in the sense that something needs to convert it to JS. React likes to claim it's just JS yet I rarely have seen react code without JSX. And JSX exists in JSX files and TSX files.
