Svelte & SvelteKit Development
Production Svelte and SvelteKit apps built by senior engineers. Smaller bundles, faster TTI, less ceremony. Subscription pricing.
Why Choose Svelte (and Why Most Agencies Cannot Build It)
Svelte ships less JavaScript to the browser than any mainstream framework, which is why teams that care about performance keep picking it — and why most agencies cannot staff Svelte work. The agency talent pipeline is React-first, with Vue as a secondary option. Svelte is treated as an exotic preference, even though SvelteKit reached 1.0 years ago and is now the most pleasant full-stack JavaScript framework in production.
The compile-time reactivity model is what makes Svelte fast, but it confuses developers who learned reactivity through React hooks. Reassigning a variable is what updates the DOM. Stores subscribe via the `$` prefix. The runtime is tiny because most of the work happens during compilation. Engineers who have not worked in Svelte before write Svelte code that looks like React, which defeats the point.
SvelteKit changed the deployment story. File-based routing, layout groups, server hooks, form actions, streaming SSR — these are first-class concerns in SvelteKit. Adapter-vercel, adapter-cloudflare, and adapter-node each have quirks. A junior developer who has shipped one SvelteKit site to Netlify will not know how to configure edge functions on Cloudflare Workers without breaking your sessions.
The component model is genuinely simpler than React or Vue, but that simplicity hides the rough edges. Cross-component communication via stores is easy to misuse. Reactive statements (`$: ...`) can trigger update loops if you are not careful. The `bind:` directive is powerful but bypasses normal data flow. You need an engineer who has run into these problems before and knows how to design around them.
AsyncForge has senior Svelte engineers shipping production code today. Submit a SvelteKit route, a reusable component, a store refactor, or a full migration from Next.js to SvelteKit. Light delivers in 4 days, Standard in 48 hours, Pro the next business day. No agencies pretending Svelte is just "React without JSX" — actual engineers who picked this framework for the same reasons you did.
What You Get
SvelteKit applications
Full SvelteKit apps with file-based routing, layout groups, server load functions, form actions, and proper error boundaries. We use the framework idiomatically — `load` functions for data, `actions` for mutations, hooks for cross-cutting concerns — rather than bolting on patterns from other frameworks.
Reactive stores done right
Writable, readable, and derived stores composed cleanly with no global state spaghetti. Cross-page state lives in `+page.server.ts` where possible; client-only stores stay scoped to feature directories. We avoid the common trap of treating every piece of state as a global store.
Edge & serverless adapters
Deploys to Cloudflare Workers, Vercel Edge, Netlify Edge, or a long-running Node server, picked based on your latency and pricing constraints. We handle the adapter-specific quirks (cookies on Workers, request size limits on Vercel, streaming response support).
Form actions & progressive enhancement
Forms that work without JavaScript first, then enhance via `use:enhance` when the runtime loads. This pattern is fast, accessible, and crawlable — but only when implemented correctly with proper redirect handling and field-level validation feedback.
Animations with the built-in transition system
Smooth transitions and animations using Svelte's built-in `transition:`, `animate:`, and `crossfade` primitives rather than dragging in a heavy animation library. Page transitions, list reorderings, modal entrances — all using the platform.
Migrations to Svelte
Incremental migrations from React, Vue, or jQuery codebases. We move features one route at a time, running both stacks in parallel behind a reverse proxy until the old app can be decommissioned.
