# OneDollarStats

The c15t oneDollarStats helper loads the OneDollarStats tracker only after visitors allow measurement in Inth. It needs no API key, and c15t reloads the page when consent is withdrawn.

## Key facts

- **Tool:** OneDollarStats
- **Category:** Analytics

Load the OneDollarStats tracker only after visitors allow measurement. It needs no API key, so setup takes one line.

Inth keeps the consent record of each choice, with the visitor’s country and the policy that applied.

## Before you start

You need an Inth project that connects to your app and c15t in that app. OneDollarStats needs no API key.

New to c15t? Complete the quickstart for your framework first. Keep its Inth endpoint, policy, styles and consent UI.

## How consent works with OneDollarStats

The c15t oneDollarStats helper adds stonks.js only while measurement has permission. It sends no consent signal to OneDollarStats.

The tracker follows client side navigation itself. It also adds history hooks and event listeners that the removal of its script cannot stop.

That is why the c15t reload on withdrawal matters here. Keep reloadOnConsentRevoked on.

## Installation

OneDollarStats has one load mode in c15t. The helper waits for measurement permission.

### Wait for permission

No request goes to OneDollarStats until the visitor accepts measurement.

```ts
oneDollarStats()
```

An opt-out policy or no policy gives optional categories permission before a choice. Then OneDollarStats loads on the first page. This guide uses an opt-in policy.

## Setup steps

#### Install the integration package

Add the helpers next to c15t. An import alone does not start the tracker.

```
pnpm add @c15t/integrations
```

#### Add the helper

Each setting that you pass becomes a data attribute on the script. Setting values are strings, such as 'true' for devmode.

```
import { oneDollarStats } from '@c15t/integrations/one-dollar-stats';

export const scripts = [oneDollarStats()];
```

Setting names use lowercase letters, digits and hyphens. The helper throws an error for other names and for values that are not strings.

### Register it with your existing setup

#### Next.js

Add scripts to c15t.config.ts, next to next.config.ts. Keep the rest of your config, such as mode, in the same call. App Router, Pages Router and static export read the same file.

```
import { defineConsentConfig } from 'c15t/next';
import { scripts } from './src/consent-scripts';

export default defineConsentConfig({ scripts });
```

#### TanStack Start

Pass scripts to the ConsentRoot in your root route. Import helpers in the route module, not in a server function: script configurations carry callbacks.

```
import { scripts } from '../consent-scripts';

<ConsentRoot state={consent} scripts={scripts}>
```

#### React

Add scripts to the options of your ConsentProvider, next to mode. Keep the banner, dialog and preferences link inside the provider.

```
import { scripts } from './consent-scripts';

<ConsentProvider options={{ mode, scripts }}>
```

#### Nuxt

Register scripts under the c15t key in app.config.ts. Keep them out of nuxt.config.ts, which reaches the browser as JSON and drops the helper callbacks.

```
import { scripts } from '../src/consent-scripts';

export default defineAppConfig({
  c15t: { scripts },
});
```

#### Vue

Pass scripts to the c15tVue plugin call you have now. The plugin starts one script loader when the app mounts.

```
import { c15tVue, manifest } from 'c15t/vue/vue-plugin';
import { scripts } from './consent-scripts';

app.use(c15tVue, {
  mode: manifest(),
  scripts,
});
```

#### Astro

Add scripts to the client entrypoint, which the integration finds on its own. Keep helpers out of astro.config.mjs: its options are serialized into the page.

```
import type { C15tClientOptionsExtension } from 'c15t/astro';
import { scripts } from './consent-scripts';

export default { scripts } satisfies C15tClientOptionsExtension;
```

#### Svelte

Pass scripts as a prop to the ConsentProvider you have now. The provider owns the loader and disposes it on unmount.

```
<script lang="ts">
  import { ConsentProvider, manifest } from 'c15t/svelte';
  import { scripts } from './consent-scripts';
</script>

<ConsentProvider mode={manifest()} {scripts}>
  <!-- Your app and consent UI -->
</ConsentProvider>
```

#### SvelteKit

Add scripts to the ConsentRoot in the root layout. Import helpers in the layout component, not in +layout.server.ts: a server load cannot send functions to the browser.

```
<script lang="ts">
  import { ConsentRoot } from 'c15t/svelte';
  import { scripts } from '../consent-scripts';

  let { children, data } = $props();
</script>

<ConsentRoot state={data.consent} {scripts}>
  {@render children()}
</ConsentRoot>
```

#### HTML: Paste the vendor’s snippet behind consent

The helpers need a bundler. On a page with the c15t script tag, paste the vendor’s own snippet instead and keep it inert until visitors allow its category. Helper options, such as loadMode, do not apply.

```
<script type="text/plain" data-c15t-category="measurement">
  // The vendor's snippet, unchanged
</script>
```

#### JavaScript

Pass scripts to init() from @c15t/browser, next to your mode. With createConsentRuntime, pass scripts to it instead.

```
import { init, manifest } from '@c15t/browser';
import { scripts } from './consent-scripts';

const consent = init({
  mode: manifest(),
  scripts,
});
```

Remove the old stonks.js script tag, so the tracker loads only through c15t. If you already have a scripts array, add the helper to it.

## Verify your setup

Use a private window with an opt-in policy. Open DevTools Network and filter by onedollarstats. Then test the three states.

- **Before a choice**: No request goes to assets.onedollarstats.com. Click Reject and reload. There is still no request.

- **After you allow measurement**: stonks.js loads without a page reload. Its script element has the data settings that you passed.

- **After you withdraw measurement**: Save your choice. c15t reloads the page. The new page sends no request to OneDollarStats.

Go to a different route and make sure that each route sends a page view. To record local visits, set devmode and hostname.
