The `public/` folder at the root of your app holds static files — images, icons, fonts, or any other assets your app needs at runtime. These files are automatically included in builds, synced during dev mode, and uploaded to the server.

Files placed in `public/` are:

- **Publicly accessible** — once synced to the server, assets are served at a public URL. No authentication is needed to access them.
- **Available in front components** — use asset URLs to display images, icons, or any media inside your React components.
- **Available in logic functions** — reference asset URLs in emails, API responses, or any server-side logic.
- **Used for marketplace metadata** — the `logo` and `galleryImages` fields in `defineApplication()` reference files from this folder (e.g., `public/logo.png`). These are displayed in the marketplace when your app is published. External absolute URLs are ignored for these fields — bundle the images in `public/` instead. Each image must not exceed 10 MB.
- **Auto-synced in dev mode** — when you add, update, or delete a file in `public/`, it is synced to the server automatically. No restart needed.
- **Included in builds** — `yarn twenty dev:build` bundles all public assets into the distribution output.

## Accessing public assets with `getPublicAssetUrl`

Use the `getPublicAssetUrl` helper from `twenty-sdk` to get the full URL of a file in your `public/` directory. It works in both **logic functions** and **front components**.

**In a logic function:**

```ts src/logic-functions/send-invoice.ts
import { defineLogicFunction } from 'twenty-sdk/define';
import { getPublicAssetUrl } from 'twenty-sdk/utils';

const handler = async (): Promise<any> => {
  const logoUrl = getPublicAssetUrl('logo.png');
  const invoiceUrl = getPublicAssetUrl('templates/invoice.png');

  // Fetch the file content (no auth required — public endpoint)
  const response = await fetch(invoiceUrl);
  const buffer = await response.arrayBuffer();

  return { logoUrl, size: buffer.byteLength };
};

export default defineLogicFunction({
  universalIdentifier: 'a1b2c3d4-...',
  name: 'send-invoice',
  description: 'Sends an invoice with the app logo',
  timeoutSeconds: 10,
  handler,
});
```

**In a front component:**

```tsx src/front-components/company-card.tsx
import { defineFrontComponent } from 'twenty-sdk/define';
import { getPublicAssetUrl } from 'twenty-sdk/utils';

const CompanyCard = () => {
  const logoUrl = getPublicAssetUrl('logo.png');

  return <img src={logoUrl} alt="App logo" />;
};

export default defineFrontComponent({
  universalIdentifier: '...',
  name: 'company-card',
  component: CompanyCard,
});
```

The `path` argument is relative to your app's `public/` folder. Both `getPublicAssetUrl('logo.png')` and `getPublicAssetUrl('public/logo.png')` resolve to the same URL — the `public/` prefix is stripped automatically if present.
