# Using Cloudflare Workers

*Please use at least version **`1.6.0`** of* `@spindl-xyz/attribution` *or* `@spindl-xyz/attribution-lite` *for this feature.*

Make sure you're logged into [cloudflare](https://www.cloudflare.com/). Workers are really easy to set up and allow up to 100,000 **free** requests per day on the [free plan](https://developers.cloudflare.com/workers/platform/pricing/). 

### 1. Create a worker <a href="#id-1-create-a-worker" id="id-1-create-a-worker"></a>

From Cloudflare dashboard, select:  `Workers & Pages` > `Overview` > `Create application` > `Create Worker`. At this point, you can either keep the random worker name or choose your own. Click `Deploy` once done.

### 2. Configure as proxy

Click `Edit code` or `Quick edit` once the worker is set up and paste the code. You should now be seeing a code editor for the worker. You can copy/paste code below which will forwards the traffic and data to our server on `spindl.link`

```javascript
const API_HOST = "spindl.link"

async function handleRequest(event) {
    const url = new URL(event.request.url)
    const pathname = url.pathname
    const search = url.search
    const pathWithParams = pathname + search
    return forwardRequest(event, pathWithParams)
}

async function forwardRequest(event, pathWithSearch) {
    const request = new Request(event.request)
    return await fetch(`https://${API_HOST}${pathWithSearch}`, request)
}

addEventListener("fetch", (event) => {
    event.passThroughOnException()
    event.respondWith(handleRequest(event))
})
```

When done, click "Save and deploy".

### 3. Configure Spindl SDK to use Proxy domain

Copy the `xxx.workers.dev` domain that you just created! Please make sure that domain doesn't include any common words that are more likely to be blocked by ad blockers including `track`, `analytics` and `spindl`

In the sdindl sdk configure object, paste the worker url as the `host`:

```javascript
spindl.configure({
  sdkKey: "<your SDK API key here>",
  host: "https://your-worker-url.workers.dev"
});
```
