Solid.js Frontend Website Development

Solid.js Frontend Website Development

Solid.js is a reactive framework that compiles into native DOM code without virtual tree. No reconciliation overhead, no re-render of entire component tree. If you need React-like DX with performance close to vanilla JS, Solid.js covers it.

Why Solid.js, not React or Vue

Components in Solid run once. No hooks with rules, no dependence on call order. Reactivity built via createSignal, createMemo, and createEffect — compile-time primitives that generate precise DOM subscriptions.

Project architecture

Standard stack for production Solid.js project:

• SolidStart — full-stack meta-framework (SSR/SSG/SPA modes)
• @solidjs/router — client and server routing
• @tanstack/solid-query — async data and caching
• solid-primitives — additional reactive primitives
• Vite — build, HMR, code splitting

// Example component with reactive state
import { createSignal, createMemo, For } from 'solid-js';

function ProductList(props) {
  const [filter, setFilter] = createSignal('');

  const filtered = createMemo(() =>
    props.items.filter(p =>
      p.name.toLowerCase().includes(filter().toLowerCase())
    )
  );

  return (
    <div>
      <input value={filter()} onInput={e => setFilter(e.target.value)} />
      <For each={filtered()}>
        {item => <ProductCard item={item} />}
      </For>
    </div>
  );
}

createMemo recalculates only when filter() or props.items change — without unnecessary iterations.

What's included in development

Basic integration (1–2 weeks)

• SolidStart + Vite + TypeScript setup
• Routing configuration with lazy-loading routes
• TanStack Query integration for API work
• Basic animations via Motion One

Full frontend (3–5 weeks)

• Component library matching client design system
• Forms with validation via @modular-forms/solid
• REST/GraphQL API integration (Axios or fetch + typing)
• SSR mode via SolidStart with createRouteData
• Core Web Vitals optimization: LCP < 1.5s, CLS = 0

Implementation specifics

State management solved via built-in primitives without external state managers. For global state use Context + Signal pattern:

import { createContext, useContext, createSignal } from 'solid-js';

const CartContext = createContext();

export function CartProvider(props) {
  const [items, setItems] = createSignal([]);
  const add = (item) => setItems(prev => [...prev, item]);
  return (
    <CartContext.Provider value={{ items, add }}>
      {props.children}
    </CartContext.Provider>
  );
}

export const useCart = () => useContext(CartContext);

Streaming SSR available out of box in SolidStart — components delivered to client as ready via Suspense and <Show>, without HTML stream blocking.

Timeline and stages

• Week 1: environment setup, component base, routing
• Weeks 2–3: business logic, API integration, forms
• Week 4: SEO, SSR or SSG, bundle optimization
• Week 5: testing (Vitest + @solidjs/testing-library), deployment

Deployment and infrastructure

SolidStart supports adapters for Vercel, Netlify, Cloudflare Workers, Node.js. Static mode generates clean HTML + minimal JS hydrator. For Cloudflare Workers bundle size matters — Solid.js bundle at 7 KB has direct business value here.

If project already on React — migration possible gradually. Solid.js components can be embedded in existing page via render() without rebuilding everything.
