Why I Moved from React to SvelteKit

Why I Moved from React to SvelteKit



When I first started learning frontend development, React was my go-to choice. The documentation was complete, the ecosystem massive, and nearly every job listing mentioned it.
But after a few years, I began to feel React becoming heavier — especially for small projects or quick prototypes.

Then I tried SvelteKit, and everything changed.

_

1. React Started to Feel “Heavy”



React is powerful, but also complex.
Here are a few things that started to frustrate me:
  • Too much boilerplate (importing useState, useEffect, etc. for simple tasks)

  • Managing bundlers (Vite/Webpack) manually

  • Needing extra dependencies for basic things (routing, state management, etc.)

  • Components becoming bloated and hard to read as projects grew


  • React gives a lot of freedom — but sometimes too much, forcing us to manage countless details just to get started.


    For example, here’s a simple counter in React:

    ``jsx
    // Counter.jsx
    import { useState } from "react";

    export default function Counter() {
    const [count, setCount] = useState(0);

    return (

    You clicked {count} times




    );
    }
    `

    2. SvelteKit Feels More “Natural”



    The first thing I noticed with SvelteKit was how natural it felt:
  • No overthinking about state and reactivity

  • Reactivity feels intuitive, using plain let variables

  • File-based routing out of the box

  • SSR (Server Side Rendering) integrated by default


  • Here’s the same counter in Svelte:

    `svelte


    You clicked {count} times



    `

    No
    useState, no hooks, no extra imports — everything feels straightforward and intuitive.
    It made UI development feel fun again.

    3. Performance & Build Size



    Svelte produces smaller and faster builds because:
  • It compiles directly to pure JavaScript, instead of running a Virtual DOM.

  • Loading and interactivity are noticeably lighter, especially for small to medium apps.


  • Comparison example:

    `bash

    Build Size Comparison


    React App: 120 KB (minified)
    SvelteKit App: 40 KB (minified)
    `

    | Numbers may vary depending on dependencies, but the difference is clear. |

    4. Developer Experience (DX)



    The combination of SvelteKit + Vite is incredibly efficient:
  • Super-fast hot reload

  • Clear and human-friendly error messages

  • New projects can be set up in seconds

  • Built-in adapters for Vercel, Netlify, and Cloudflare


  • Creating a new SvelteKit project is as simple as:

    `bash
    npx sv create my-app
    cd my-app
    npm run dev
    `

    You instantly get automatic routing (
    +page.svelte, +layout.svelte`) without extra configuration.

    5. When React Still Makes Sense



    Of course, that doesn’t mean React is bad.
    I’d still choose React if:
  • The project is large and involves multiple teams with complex dependencies

  • I’m building mobile apps using React Native

  • I need a specific UI library that’s only available for React


  • But for personal projects, portfolios, or lightweight dashboards — SvelteKit is simply more enjoyable.


    _

    Conclusion



    Switching to SvelteKit made me fall in love with frontend again.
    Cleaner code, faster performance, and a much more enjoyable development process.

    If React feels like too much for simple projects, maybe it’s time to give SvelteKit a try.
