Код (Lua):

do
srv = net.createServer(net.TCP)
function receiver(sck, data)
  local response = {}
  -- if you're sending back HTML over HTTP you'll want something like this instead
  -- local response = {"HTTP/1.0 200 OK\r\nServer: NodeMCU on ESP8266\r\nContent-Type: text/html\r\n\r\n"}
  response[#response + 1] = "lots of data"
  response[#response + 1] = "even more data"
  response[#response + 1] = "e.g. content read from a file"
  -- sends and removes the first element from the 'response' table
  local function send(localSocket)
  if #response > 0 then
  localSocket:send(table.remove(response, 1))
  else
  localSocket:close()
  response = nil
  end
  end
  -- triggers the send() function again once the first chunk of data was sent
  sck:on("sent", send)
  send(sck)
end
srv:listen(80, function(conn)
  conn:on("receive", receiver)
end)
end
