Plausible Analytics is a privacy-friendly, cookieless analytics product with a lightweight script loader. The `plausibleAnalytics()` helper models Plausible's queue bootstrap and script attributes as a c15t-managed script so early `window.plausible(...)` calls are buffered safely until the tracker loads.

## Integrate with c15t

**React**

```tsx
import { type ReactNode } from 'react';
import { ConsentManagerProvider } from '@c15t/react';
import { plausibleAnalytics } from '@c15t/scripts/plausible-analytics';

const scripts = [plausibleAnalytics({ domain: 'example.com' })];

export function ConsentProvider({ children }: { children: ReactNode }) {
  return (
    <ConsentManagerProvider
      options={{
        mode: 'hosted',
        backendURL: 'https://your-instance.c15t.dev',
        scripts,
      }}
    >
      {children}
    </ConsentManagerProvider>
  );
}
```

**Next.js**

```tsx
'use client';

import { type ReactNode } from 'react';
import { ConsentManagerProvider } from '@c15t/nextjs';
import { plausibleAnalytics } from '@c15t/scripts/plausible-analytics';

const scripts = [plausibleAnalytics({ domain: 'example.com' })];

export function ConsentProvider({ children }: { children: ReactNode }) {
  return (
    <ConsentManagerProvider
      options={{
        mode: 'hosted',
        backendURL: '/api/c15t',
        scripts,
      }}
    >
      {children}
    </ConsentManagerProvider>
  );
}
```

**JavaScript**

```ts
import { getOrCreateConsentRuntime } from 'c15t';
import { plausibleAnalytics } from '@c15t/scripts/plausible-analytics';

getOrCreateConsentRuntime({
  mode: 'hosted',
  backendURL: 'https://your-instance.c15t.dev',
  scripts: [plausibleAnalytics({ domain: 'example.com' })],
});
```

## How c15t loads it

* **Category:** `measurement` (Analytics)
* **Loads when:** measurement consent is granted
* **On revocation:** unloaded — c15t removes the script element from the DOM. Plausible is cookieless, so no client-side state needs clearing.

If you need script extensions or hash-based routing support, pass them through the helper:

```ts
plausibleAnalytics({
  domain: 'example.com',
  extension: ['file-downloads', 'outbound-links'],
  hashBasedRouting: true,
})
```

The helper seeds a `window.plausible` queue stub during `onBeforeLoad`, so any calls made between the consent grant and the real script attaching get buffered into `plausible.q` and replayed. It also maps the legacy `data-domain` / `data-api` attributes and the new `scriptId`-based loader URL automatically.

## Tracking events in your app

c15t gates the Plausible script from loading until `measurement` consent is granted. Your application code that calls Plausible is **not** automatically gated — `window.plausible` does not exist until the script is loaded, so unguarded calls before consent throw.

Guard event calls by checking consent state. From React:

```tsx
import { useCallback } from 'react';
import { useConsentManager } from '@c15t/react';

function useTrackSignup() {
  const { has } = useConsentManager();

  return useCallback(() => {
    if (has('measurement')) {
      window.plausible?.('Signup');
    }
  }, [has]);
}

function SignupButton() {
  const trackSignup = useTrackSignup();

  return (
    <button type="button" onClick={trackSignup}>
      Sign up
    </button>
  );
}
```

From plain JavaScript:

```ts
import { getOrCreateConsentRuntime } from 'c15t';

const { consentStore } = getOrCreateConsentRuntime();

if (consentStore.getState().has('measurement')) {
  window.plausible?.('Signup');
}
```
