how to make if within 30 seconds

How to write an error to the console when I have not received an answer within 30 seconds?

const req = await axios.post(`http://316.132.61.31:2000`)
  .catch(err => console.log(err));

I need to understand how it works

>Solution :

You just need to use timeout option:

timeout specifies the number of milliseconds before the request times out.
If the request takes longer than timeout, the request will be aborted.
timeout: 1000, // default is 0 (no timeout)

const req = await axios.post(`http://316.132.61.31:2000`, null, { timeout: 30000 }).catch(err => console.log(err));

See the official documentation here

P.S. Please read the documentation before asking your next question about axios and indicate what you tried and what options you used in the question.
