TCP/TLS listener: Ping
An example of a TCP listener using TLS on localhost that will log the message if written to and close the connection if connected to.
Instantiate an instance of a TCP listener on localhost port 443.
const listener = Deno.listenTls({
hostname: "127.0.0.1",
port: 443,
transport: "tcp",
cert: Deno.readTextFileSync("./server.crt"),
key: Deno.readTextFileSync("./server.key"),
});Await asynchronous connections that are established to our TCP listener.
for await (const conn of listener) {Pipe the contents of the TCP stream into stdout
await conn.readable.pipeTo(Deno.stdout.writable);We close the connection that was established.
conn.close();
}Run this example locally using the Deno CLI:
deno run --allow-net --allow-read https://docs.deno.com/examples/scripts/tls_listener.ts
