11_None of this information is useful. The reason-phrase is barely supported on the web and was always an oddity, but keep reading if you like oddities!_

13If you're used to JavaScript’s `fetch()` method to make HTTP requests, you've seen the `reason-phrase` under a different name: `statusText`:
14
15```ts
16(await fetch('https://example.com/')).statusText
17```
18
48```

50Unfortunately, this doesn't work! The response that Val Town produces is reorganized and optimized by Cloudflare, which upgrades requests and responses from HTTP 1.1 to HTTP 2. And sadly, HTTP 2 [dropped support for the custom reason-phrase](https://fetch.spec.whatwg.org/#concept-response-status-message).
51
52_RIP the `reason-phrase`._ It was present even in a [1992 draft of the HTTP specification](https://www.w3.org/Protocols/HTTP/Response.html), and was a weird and under-appreciated way to pilfer extra information in a response. Now, thanks to HTTP/2 and the commonplace use of proxies and CDNs like Cloudflare, it's no longer usable. It was fun while it lasted.
1# DuckDB
2
3[DuckDB](https://duckdb.org/) works on Val Town, with only one small tweak! We're basically using DuckDB in the same way you'd use it with a browser - using the WASM package with its dependencies fetched from [jsdelivr](https://www.jsdelivr.com/).
4
5The only trick is to create the worker ourselves rather than using `duckdb.createWorker`. DuckDB's built-in createWorker method doesn't specify a worker type, which causes `type` to default to `classic`, and Deno (our runtime) doesn't support classic workers.
3Example of using the [are.na](https://dev.are.na/documentation/channels#Block43472) API to get the contents of an Are.na board - specifically my fun board that showcases websites with that "glossy black style."

5All you need is [fetch](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) to make this happen!

3The [ky module](https://www.npmjs.com/package/ky) is a nice abstraction around the [fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API), which is easily compatible with Deno. It's by the same creator as [got](https://npmjs.com/got), which more explicitly targets Node.js.

5Most of the time, the `fetch` method is all you need! But in a pinch, you can use `ky` to make things a little fancier.

3This val fetches itself via the [Val Town API](https://docs.val.town/api/reference)! Weird, right?
