Svelte Advantages Over React and Vue
Any advantage of using Svelte instead of React or Vue?
Is it just because of performance?
Easier to integrate "raw" JavaScript libraries because Svelte acts on real DOM objects, not virtual ones. This is why I continue to use it, the performance advantage is just a bonus to me.
For Vue at least, a vanilla JS library is a composable an away from integration. Vue uses the virtual domain for diffing, but it updates the dom on setup, and subsequent updates only occur atomically after state changes.
React gets dicier with rerenders.
I agree. I've run into a few times where I needed to integrate vanilla javascript libraries and it just works with svelte.
I haven't used vue in ages so don't know or remember if it has similar capabilities.
Granular reactivity?
No need to ship a runtime since Svelte doesn’t use a virtual dom.
Svelte has a runtime with svelte 5 for runes and signals - but it is small and enables applications to scale much better in size than before. So before svelte 5 there was no runtime, but therefore code was "duplicated" between components. Now it is a bit bigger to start with, but therefor the application grows a lot slower than before. So for most purposes applications are now smaller than before.
I thought it uses JavaScript signals underneath.
Sure, signals are implemented in JavaScript, but there is no standard for signals in JavaScript. I think there was a proposal for one a while ago, but it is not a standard yet.
its just nicer to work with imo. vue is similar, but the difference between react is staggering. react forces you to learn a bunch of extra concepts and loopholes and footguns to avoid.
Sadly I converted from sveltekit to nuxt because it is just big enough to don’t worry about scaling your team on it. Svelte is great, but lacking for me to take it as a choice for building a software house company
whats lacking exactly? whats stopping a team using svelte from scaling?
Nothing outside of it being relatively green for new devs.
I'd argue that any dev smart enough to grasp React can be outperforming their React-self in Svelte within a week or so.
They'll of course still have some fumbling through "how do you do X in Svelte" translations, but even with the docs permanently open, they can typically out-pace their React hook-soup self.
It can serve the same purposes as vue or react project. I even started my company using svelte, and it's possible.
Svelte can be faster in development, but at the same time when you encounter problem it's so much harder to resolve. Not talking about talent aquisition as it's so much simpler for vue, as there are just more devs for it.
I love svelte and was always an advocate, don't take me wrong.
But when you're scaling business you want to focus on marketing and selling side, not on tech.
Why is it harder to resolve Svelte problems? The codebase is pretty well maintained by some clearly very competent people, so it's possible to take a look at why it doesn't work. Especially with AI assistance. And the documentation is pretty great too.
To me, the most confusing thing about sveltekit is how simple it is. It's like I expect more black magic than there is.
But maybe I haven't used it long enough. What kind of issues are you thinking of?
It's just not (in my experience).
I've been building in Svelte since the early days, with many apps in production. I build in React for the normal job, and Svelte for all my own stuff.
React creates an interesting paradox where it introduces many issues due to the complexity it requires.
This makes developers fear a smaller audience in Svelte because they wonder "who would answer all these questions I always have???" But the answer is closer to "many of these questions you would not even have in Svelte".
This is also why I maintain that any dev smart enough to hold their own in React can absolutely crush it (in no time) in Svelte.
Yeah agreed, that's exactly what I mean. The scariest thing is that there's not a lot to worry about in Svelte so it looks like something is missing
The worst issues I've had to deal with using Svelte were the subtle differences in how chains of derived store dependencies and reactive $: statements handled updates, creating differences in behaviour to apparently equivalent logic.
But even that was predictable, architecturally understandable, easy to work with and so hardly ever a significant issue that most experienced Svelte devs are not even aware of this.
And then runes came into the picture, which are much closer t9 stores semantically and the issue is even less significant.
I feel like i'm one of the few that don't actually love runes... they're awesome in some cases, and feel like a DX regression in others.
Totally agree w you on some of the reactivity challenges, but then every reactive framework seems to have that issue in some way or another (certainly in React in my experience). That said, I feel like I write less code and it's far more human-readable than the hook-soup necessities in React!
Absolutely
for agentic coding less token expediture
Ah, lol, I didn't though about this one
Wrong until you prove it
Haven’t tried recently but i felt the opposite a few months back as dumb models just installed react packages even though I told it not to.
I found it easy to use when creating an image generator library with a .png route this just isn't some to you can do in vue. You can in react since it supports those server side functions. Svelte felt easier and cleaner when I tested both. (Used for generating unique headers for posts on a blog based on a slug version of the title as the seed)
Less stress
Virtually everything except job market
I might get downvoted for saying this, but I think the job market is equally challenging nowadays regardless of the library or framework, and this is becoming an old discussion.
Indeed, AI is helping companies change their tech stacks and the adoption of SvelteKit is increasing. Trust me bro!
For what it's worth, AI is what made me start "using" Svelte for the first time. I couldn't justify it before, despite researching and concluding it is overall likely the best framework, but now that I can basically rewrite anything in anything, I went from never touching Svelte to using it everywhere. Agents seem to work well with it.
I have never actually written a line of Svelte code myself - or, frankly, any frontend code, pre-AI I've always just worked with messy vanilla JS/TS behemoths - but I basically just batter the AIs with "okay try to split this into more components and re-use these existing components instead of re-inventing new components just for this" every so often and the end result seems decent enough
Svelte costs less tokens. Seriously!
I developed a complex website 3x using Svelte, React and Vue using Claude 4.8
Svelte was much cheaper.
Just like elixir is cheaper than Python
Zig is cheaper than rust
Elixir development is cheaper than most languages.
Does it really matter anymore what the language is? It’s all about speed and token cost not man days.
It’s: How fast you can achieve a bug free solution using the minimum number of tokens.
The technologies that are cheapest to develop with LLMs should prevail unless the token vendors can influence the technology stacks.
But, hey we’ve been driving gasoline cars for hundreds years - which is proof that when it comes to technology the markets are never efficient.
Hahaha oh lord imagine optimizing for hireability for hand-coding jobs in 2026
While not hand-coding, the job openings still require experience in the specific language and framework and infra the project is using, not just in some language, framework, and infra.
Cause you still need to be able to tell where the output makes sense amd where it doesn't
very clear comment
Oh man. Slam dunk comment.
Clearer and simpler code, less footguns and framework idiosyncrasies, no vDOM (it goes beyond performance).
BTW, there are a growing number of high-performing big players (not enough) that have gone full on Svelte (Apple, Hugging face,...).
Yes, you will have fun debugging when they ship a completely broken version of the framework
Other than that, DX is much, much worse. TS integration is also much worse. Svelte is a fun framework if you use it on your to-do list type of project.
Software has bugs, they fixed it already. Get over it.
mehhhhh they released a fixed version in 24 hours. You shouldn't be installing packages that young anyway in this day and age courtesy of supply chain attacks.
>mehhhhh they released a fixed version in 24 hours
They did?
https://www.npmjs.com/package/svelte?activeTab=versions
I thought the broken version was the one that was the latest for 3 days with 130k downloads.
You update to the newest verions of all your packages, in production? Are you begging to be hacked? No minimum age policy? At all?
You'd better quit drinking
DX.
I studied React for like 3 times, different courses, dozens of pet projects. It took me about 4 months before it clicked.
But with Svelte I was ready to create within 3 days of studying.
BTW it's ridiculous that Svelte feels closer to Vanilla JS, than React. Even though it's DSL.
My experience as well. Quite a few years of React building under my belt before I touched Svelte, and I within a day or two I was already faster at the latter.
Even just going through the tutorials back then was one mind-blown reaction after another... thinking "omg, this would have taken so much more in React (or it just isn't even natively handled)".
React has a dsl too, JSX is not vanilla
JSX is synthetic sugar for React.createElement()
Yeah, it is syntactic sugar.
Vue templates are sugar for Vue createElement
Svelte templates are sugar for dom operations
They each use non standard file extensions, .tsx/jsx, .vue and .svelte.
All are DSLs that are not compatible with vanilla JS
hmm, makes sense
Mental health
clean syntax, almost same like vue,
not too much need ext deps
Remote functions: https://svelte.dev/docs/kit/remote-functions
And now they support real time streaming.
Been writing React professionally since it was a niche new library from Facebook. Svelte is better in every way.
Actually linting tools are better for React still.
Same team on both accounts! Still work in React to this day (for work), and can still safely say Svelte is just cleaner, simpler, better performance, and solves so many app-level issues that React does not.
Any? 😂 Made my day
It’s good for embedded web development cause it uses less storage
it is hard to write bad code. the compiler just does the heavy lifting. A production dashboard was 2MB on my React MVP to 500kb in mt Svelte Code. Everything loads fast, the app is snappy, code is not callback hell. Less compromised package ecosystem, less libraries to learn. it just works.
- DX
- Prob save more tokens for agentic coding
- No strange concepts to learn... unlike React
Svelte simply revolutionized front-end development.
Front-end is two things.
- You declare what your HTML/CSS is for a given set of variables (state): that's templating.
- You write the logic connecting user actions to changes in that state: that's programming.
That's the whole job.
Svelte 5 took both and perfected them.
Programming: with runes, a state is just a TypeScript variable. let count = $state(0), then count++. You change a variable by changing it. Nothing special, pure TypeScript.
Templating: you make a .svelte file and write HTML/CSS with a great templating language, by using those state variables you wrote in pure TypeScript. It's perfect.
Now React.
Programming: a state isn't a variable, it's a hook. const [count, setCount] = useState(0). You have to go through setCount. You don't change a regular TypeScript variable. You ask React to change it for you via API.
Templating: a component is a function, and the template is whatever that function returns.
But look at where the template lives: inside the function. useState only works inside that same function. So your state and your template are forced to live in the exact same place, one inseparable block. You can't put your state in one file and your template in another. React welds them together by design.
Svelte doesn't. Your state can live in its own .svelte.ts file, with its own in pure TypeScript logic. Your template (.svelte file) can import whatever states it needs from .svelte.ts files, and connect buttons to the necessary logic.
These are just some things off the top of my head, and this is only the frontend side. SvelteKit is also revolutionary in its own for full-stack.
Angular for the streets, Svelte for the sheets
You keep your sanity?
Everything
Easier on the coding agents. They can reason easier with svelte as things aren't too abstracted away.
Just use that what AI is best at.
You'll love it. Thats the biggest advantage.
One library for Frontend and Backend, React can do too, however Reac makes it complicated.
Clean Code, Less code
react: we have solutions to your problems, and then we have solutions to the problems that our previous solutions made... and now you're downloading 600kb worth of react on page load
svelte: we got reactivity... state management... and JavaScript, figure out the solution to your problem by yourself bro
The pivot would be Web Components, and smart use of bundling. We don't need to fully rely on a full set framework. Pick whatever that works for small scope, build components/widget and wrap the context so that AI can better delivery, and you can control the quality as well. But this doesn't matter since we want to make everything proprietary with Rust/Go and Web Assembly.
I'd say the question is "vs react". so, developer experience.
Vue has a pretty much identical DX.
Developer Experiance is just waaaay nicer, worked for 3 years in a Svelte, SvelteKit, Typescript, GraphQL stack. It was a bless. Miss those days.
Can you elaborate a bit by nicer?
React often feels like you need a whole list of dependencies just to get basic things working. A lot of it can feel hacky, not very rounded, and full of weird concepts or hidden pitfalls that are not obvious at first. Over time, it feels bloated, especially in complex components like a checkout / payment or similar things.
I worked on an online shop for a fashion label here in Germany, where we replatformed from a PHP, Smarty, and Vue stack to a full rewrite with Svelte, SvelteKit, TypeScript, and GraphQL. After years of working with that legacy codebase, it was honestly refreshing to see a different approach. I was hooked on Svelte pretty quickly. It was fun to work with, and because I enjoyed it so much, I learned a lot along the way in General and even did things as Frontend Developer i would tought i never touch like writing NestJS Services we also had which was running in the background.
I got so into it that I basically led the migration from Svelte 4 to Svelte 5. I explained runes and the other major new concepts to the team, since that version changed quite a few things.
What I like about Svelte is that it feels idiomatic, simple, and straightforward with minimal code. You do not constantly have to fight the framework or think through layers of side effects. Most of the time, you just write the code and it works the way you expect.
Even today all my private projects are built with Svelte, SvelteKit, and TypeScript.
If you are curious, try the tutorial on https://svelte.dev/tutorial/svelte/welcome-to-svelte It shows pretty quickly how easy and convenient the framework is to use. :)
