socket.io connection not working but new Websocket working

Question

I' have a socket server i just try to connect that server.

when i try new Websocket my connection is works;

const socket = new Websocket('ws://127.0.0.1:8000');

but when i want to use socket.io like this;

const socket = io('ws://127.0.0.1:8000');
socket.on('connect', () => {
  console.log('connected');
});

socket io code can't connect to socket it's fired cors error everytime but new Websocket connection works easly.

I found a solution like this;

  socket = io('ws://127.0.0.1:8000', {
    "transports": [
      "websocket"
    ]    
  });

i added transports datas then socket start works.

Answer 1

This worked for me socket = io('ws://localhost:8000',{transports:['websocket']});
