How to make data exchange through axios correctly?

Question

Node.js

You need to do data exchange through two remote machines.
On the server I start the listener on port 3306 http.listen(3306) ...
On the client I send data:
await axios({
timeout: 10000,
method: 'post',
data: data
});

Data successfully arrives at the server.
How to send back data from the server to the client?
It turns out in the same way, through axios I send data to the client. And on the client I launch the http.listen(3306) port listener?
Goes to the server has axios and listener and on the client axios and listener. It turns out that the server is a client and the client is a server

Answer 1

You can't send data to the client in this way.
Let's start by sending data to the server using a specific route, for example test
Then your handler will look something like this:

router.get('/test', (req, res) => {
  res.send('Даные, которые возвращаем обратно на клиент');
})
