## Overview

<p>Utilities for working with Deno's readers, writers, and web streams.</p>
<p><code>Reader</code> and <code>Writer</code> interfaces are deprecated in Deno, and so many of these
utilities are also deprecated. Consider using web streams instead.</p>

```js
import { toReadableStream, toWritableStream } from "@std/io";

await toReadableStream(Deno.stdin)
  .pipeTo(toWritableStream(Deno.stdout));
```

### Add to your project

```sh
deno add jsr:@std/io
```
