Hire Svelte Developers

Both are excellent. The choice depends on priorities.

Choose Svelte when you need:

• Less Code: Svelte requires significantly less boilerplate
• Smaller Bundles: No virtual DOM means smaller JavaScript payloads
• Better Performance: Compile-time optimization beats runtime frameworks
• Simpler Reactivity: No hooks confusion, just reactive statements
• Better DX: Many developers find Svelte more enjoyable to write
• Fast Build Times: Compile-time approach means faster rebuilds

Choose React when you need:

• Larger Talent Pool: React has 10x more developers (easier hiring)
• Mature Ecosystem: More libraries, components, and tools
• Mobile Development: React Native provides clear mobile path
• Corporate Backing: Meta’s resources behind React
• Job Market: React skills are more transferable

Real-World Usage:

• Svelte: The New York Times, Apple Music, Spotify (parts), 1Password, Chess.com
• React: Facebook, Netflix, Airbnb (majority of market)

Performance: Svelte often beats React in benchmarks due to no virtual DOM overhead.

Learning Curve: Svelte is generally considered easier to learn.

Bundle Size: Svelte produces significantly smaller bundles (40-60% smaller for equivalent apps).

Our Recommendation:

• Choose Svelte for performance-critical apps, embedded widgets, or teams valuing simplicity
• Choose React for larger teams, mobile needs, or prioritizing hiring ease

The Truth: Svelte is rising fast, but React still dominates the job market. Both are excellent choices in 2025.

Svelte 5 runes are the modern way to handle reactivity, replacing older reactive statements for better performance and clarity.

What are runes? Runes are compile-time signals that start with $:

• $state() - Reactive state
• $derived() - Computed values
• $effect() - Side effects
• $props() - Component props
• $bindable() - Two-way binding

Old Svelte (reactive statements):

<script>
let count = 0
$: doubled = count * 2
</script>

Svelte 5 (runes):

<script>
let count = $state(0)
let doubled = $derived(count * 2)
</script>

Why runes are better:

• More explicit and predictable
• Better TypeScript support
• Fine-grained reactivity
• Better performance
• Clearer mental model

Should developers use runes? Yes, for new Svelte 5 projects. Runes are the future of Svelte.

Migration: Existing Svelte 3/4 code still works in Svelte 5. Runes are opt-in, allowing gradual migration.

Our Svelte developers are proficient in both reactive statements (legacy) and runes (modern) to handle any codebase.

Both are excellent full-stack frameworks. Choose based on your frontend framework preference.

Choose SvelteKit when you need:

• Simpler API: SvelteKit has cleaner abstractions
• Better DX: Many developers find SvelteKit more intuitive
• Smaller Bundles: Svelte produces smaller JavaScript than React
• Form Handling: SvelteKit’s form actions are elegant
• You Prefer Svelte: The framework preference drives this choice

Choose Next.js when you need:

• Larger Ecosystem: More integrations, libraries, examples
• React Ecosystem: You’re already using React
• Hiring Ease: 10x more Next.js developers available
• Mobile Apps: React Native path for mobile
• Vercel Integration: First-class deployment experience

Feature Parity: Both frameworks offer SSR, SSG, API routes, file-based routing, and excellent performance.

Learning Curve: SvelteKit is generally considered simpler due to Svelte’s less complex model.

Performance: SvelteKit often produces smaller bundles due to Svelte’s compile-time approach.

Deployment: Both work well on Vercel, Netlify, Cloudflare Pages.

Our Recommendation: If you prefer Svelte’s simplicity, SvelteKit is the obvious choice and provides excellent full-stack capabilities. If you need React’s ecosystem or mobile, choose Next.js.

We have developers proficient in both frameworks.

Yes. SvelteKit makes SSR straightforward and provides multiple rendering strategies.

SvelteKit Rendering Options:

1. SSR (Server-Side Rendering):

• Default in SvelteKit
• Pages rendered on server for each request
• Great for dynamic content
• SEO-friendly

2. SSG (Static Site Generation):

• Pre-render pages at build time
• Use adapter-static
• Perfect for marketing sites
• Fastest possible loads

3. Hybrid:

• Mix SSR and SSG per route
• Some pages static, others dynamic
• prerender = true per route

4. CSR (Client-Side Rendering):

• SPA mode if needed
• ssr = false in routes

SEO Benefits:

• Full HTML sent to search engines
• Meta tags for social sharing
• Fast first contentful paint
• Core Web Vitals optimization

Implementation:

// +page.server.js - server-side data loading
export async function load() {
  const data = await fetchData()
  return { data }
}

Our developers implement the optimal rendering strategy for your use case, leveraging SvelteKit’s flexibility.

Svelte provides multiple elegant state management options, from simple stores to advanced patterns.

Built-in Stores:

• writable() - Mutable state
• readable() - Read-only state
• derived() - Computed values
• get() - Read store value once

Example:

// store.js
import { writable } from 'svelte/store'
export const count = writable(0)

// Component.svelte
<script>
  import { count } from './store'
</script>
<button on:click={() => $count++}>
  Clicks: {$count}
</button>

Advanced Patterns:

• Custom stores with logic
• Store subscriptions
• Context API for component trees
• Zustand (if React-style needed)
• XState (state machines)

When to use stores:

• Shared state across components
• Global application state
• Persistent data (localStorage sync)
• Complex state logic

When to use props:

• Parent-child communication
• Component-specific state
• Simple data passing

Svelte 5 Runes: With Svelte 5, $state() and $derived() provide alternative patterns that can replace stores in many cases.

Our developers choose the right state management approach based on your application’s complexity and team preferences.

Yes. Svelte has the best built-in animation system among frameworks.

Svelte Animation Features:

1. Transitions:

<div transition:fade>Fade in and out</div>
<div transition:fly={{ y: 200 }}>Fly animation</div>
<div transition:slide>Slide animation</div>

2. Built-in Transitions:

• fade
• fly
• slide
• scale
• draw (SVG)
• crossfade

3. Custom Transitions:

• Write custom CSS transitions
• Control timing and easing
• JavaScript-based animations

4. Animate Directive:

<div animate:flip={{ duration: 300 }}>
  Smooth list reordering
</div>

5. Svelte Motion:

• Spring physics
• Tweened values
• Smooth interpolation

Performance:

• No JavaScript runtime overhead
• CSS-based transitions compile to vanilla CSS
• Butter-smooth 60fps animations

Use Cases:

• Page transitions
• List reordering
• Modal animations
• Loading states
• Interactive elements

Svelte’s animation system is often cited as superior to React’s, requiring less code and delivering better performance.

Yes. Svelte is excellent for component libraries due to small output and framework-agnostic compilation.

Component Library Advantages:

• Tiny bundle sizes (no framework runtime)
• Can be used in any framework (as web components)
• Scoped styles prevent conflicts
• TypeScript support
• Storybook integration

Popular Svelte Component Libraries:

• Skeleton UI
• Carbon Components (IBM)
• Svelte Material UI
• DaisyUI (with Tailwind)
• Custom in-house libraries

Creating Component Libraries:

# SvelteKit library mode
npm create svelte@latest my-library
# Choose "Library" template

Publishing:

• Compile to npm package
• Support tree-shaking
• Provide TypeScript definitions
• Document with Storybook

Web Components: Svelte can compile to web components usable in React, Vue, Angular, or vanilla JS.

Our developers build internal component libraries for design system consistency and reusability across products.

Yes, but it’s often a rewrite rather than migration due to Svelte’s different paradigm.

Migration Strategies:

1. Incremental (Web Components):

• Build new features in Svelte
• Compile to web components
• Embed in existing React/Vue app
• Gradually replace components

2. Parallel Development:

• Build new version in Svelte
• Run both simultaneously
• Switch when ready
• Lower risk

3. Complete Rewrite:

• Rebuild from scratch
• Leverage Svelte’s simplicity for faster development
• Often results in 40-60% less code
• Timeline: 2-6 months depending on size

Challenges:

• Different reactivity model
• Different component structure
• Learning curve for team
• Tooling/ecosystem differences

Benefits After Migration:

• Smaller bundle sizes (40-60% reduction)
• Better performance
• Less code to maintain
• Improved developer experience

When Migration Makes Sense:

• Major refactor planned anyway
• Performance is critical issue
• Team excited about Svelte
• App size is manageable (< 100 components)

Our Recommendation: Migration is worthwhile for performance-critical applications or when major refactor is needed anyway. For large, established React apps, stick with React unless compelling reasons exist.

Our developers can assess your application and recommend whether migration is worthwhile.
