send a binary message to a udp server in typescript

To send a binary message to a UDP server in Typescript, you can use the built-in Node.js dgram module. Here's an example of how to do this:

index.ts
import * as dgram from 'dgram';

const client = dgram.createSocket('udp4');

const message = Buffer.from('your binary message');

client.send(message, 0, message.length, 8000, 'localhost', (err) => {
  client.close();
});
222 chars
10 lines

In this example, we create a UDP socket client using dgram.createSocket, with version udp4. Then, we define our binary message as a Buffer object using Buffer.from. Then, we call client.send to send the message to the server at localhost:8000. When the message is sent, we close the UDP socket with client.close.

Note that in client.send, the first argument is the message as a Buffer, the second argument is the offset (0 in this case), the third argument is the length of the message, and the last two arguments are the server's address and callback respectively.
