Using inside componentDidMount lifecycle hook:

useEffect(() => {
const ourRequest = Axios.CancelToken.source() // <-- 1st step

const fetchPost = async () => {
  try {
    const response = await Axios.get(`endpointURL`, {
      cancelToken: ourRequest.token, // <-- 2nd step
    })
    console.log(response.data)
    setPost(response.data)
    setIsLoading(false)
  } catch (err) {
    console.log('There was a problem or request was cancelled.')
  }
}
fetchPost()

return () => {
  ourRequest.cancel() // <-- 3rd step
}
}, [])

Note: For POST request, pass cancelToken as 3rd argument

Axios.post(`endpointURL`, {data}, {
 cancelToken: ourRequest.token, // 2nd step
})
