Solidstart Client Only

SolidStart clientOnly

The clientOnly function renders components or pages exclusively on the client side, bypassing SSR.

Component Usage

1. Create separate file for client-only component:

// ClientOnlyComponent.tsx
export default function ClientOnlyComponent() {
  const location = document.location.href;
  return <div>Current URL: {location}</div>;
}

2. Import with clientOnly:

import { clientOnly } from "@solidjs/start";

const ClientOnlyComp = clientOnly(() => import("./ClientOnlyComponent"));

export default function IsomorphicComponent() {
  return <ClientOnlyComp />;
}

3. Optional fallback:

<ClientOnlyComp fallback={<div>Loading...</div>} />

Page-Level Usage

Disable SSR for entire page:

// routes/page.tsx
import { clientOnly } from "@solidjs/start";

export default clientOnly(async () => ({ default: Page }), { lazy: true });

function Page() {
  // This code runs only on client
  return <div>Client-only page content</div>;
}

Parameters

fn: () => Promise<{ default: () => JSX.Element }>

• Function that dynamically imports component

options: { lazy?: boolean }

• lazy: true (default) - Lazy load component
• lazy: false - Eager loading

props: Record<string, any> & { fallback?: JSX.Element }

• Props passed to component
• Optional fallback for loading state

Use Cases

• Browser APIs (window, document, localStorage)
• Third-party widgets (maps, charts)
• DOM manipulation
• Avoiding SSR hydration issues
• Code that can't run on server

Best Practices

1. Isolate client-only logic in separate files
2. Provide meaningful fallbacks for loading states
3. Use sparingly - prefer SSR when possible
4. Consider progressive enhancement where possible
