Create a very, very simple example using the nodejs ws library of a client
3
and server talking to each other via a websocket.  The client and server
4
should both be nodejs processes (no web browser involved!).

6
The simple code below works fine and accomplishes the goal above.

8
In one node shell:
9

10
> wss = require('./dist/ws').server();
11
Server Received message: hi
12

13
In another:
14

15
> ws = require('./dist/ws').client();
16
> Client Received message: Welcome to the WebSocket server!
17
> ws.send("hi")
18
undefined

*/

21
import WebSocket from "ws";
22

23
export function server() {
24
  const wss = new WebSocket.Server({ port: 8080 });
25
  wss.on("connection", (ws) => {
26
    console.log("Client connected");
27
    ws.send("Welcome to the WebSocket server!");
28
    ws.onmessage = (event) => {
29
      console.log(`Server Received message: ${event.data}`);
30
    };
31
  });
32
  return wss;
33
}
34

35
export function client() {
36
  const ws = new WebSocket("ws://127.0.0.1:8080");
37
  ws.onmessage = (event) => {
38
    console.log(`Client Received message: ${event.data}`);
39
  };
40
  return ws;
41
}
