Where can I find examples of how Socket.io and Express work?

  Hello, where can I see examples of how Socket.io and Express work for different tasks.
  
  I can’t solve the problem, I can solve the problem with an example.
  
  There is
  app.get ("/ kabinet", function (request, response) {
  response.render ("kabinet.ejs", setSite)
  }), from express
  
  I can't put io.on connect into it, because the problem "Connections accumulation" appears.
  If I take out io.on separately, then how to handle functions inside io.on?
  
  Example:
  io.on ('connection', function (socket) {
  console.log ('User connected');
  sendUser (1, socket);
  });
  async function sendUser (s, socket) {
  var mm = await data.getUser (s)
  socket.emit ('sendToClient', {name: mm ['name'], inrt: mm ['rate']});
  }
  In such example there is a problem "TypeError: Cannot read property 'emit' of undefined"
  
  In general, how should they work together?
  I won't understand.
  I ask for help
