# deno_socket
A Deno Implementation of the Cloudflare Socket API
Deno already has great support for TCP, but since Cloudflare proposed a
[WinterCG spec](https://sockets-api.proposal.wintercg.org/), this provides the
same interface for Deno so we could migrate easier later on.
Inspired by `@arrowood.dev/socket`, but with Deno's runtime APIs.
## Usage
```js
import { connect } from "https://deno.land/x/socket/mod.js";
export default {
async fetch(request) {
const gopherAddr = { hostname: "gopher.floodgap.com", port: 70 };
const url = new URL(req.url);
try {
const socket = connect(gopherAddr);
const writer = socket.writable.getWriter()
const encoder = new TextEncoder();
const encoded = encoder.encode(url.pathname + "\r\n");
await writer.write(encoded);
return new Response(socket.readable, { headers: { "Content-Type": "text/plain" } });
} catch (error) {
return new Response("Socket connection failed: " + error, { status: 500 });
}
}
};
```
The module can also be run as a simple CLI to send a message to a TCP server,
similar to the example above, but send response to `stdout`.
For example:
```shell
$ deno run --allow-net mod.js gopher.floodgap.com:70 /
```
