Axios spread() with unknown number of callback parameters

I need to process an unknown number of AJAX requests (1 or more) with axios, and I am not sure how to handle the response. I want something along the lines of:

let urlArray = [] // unknown # of urls (1 or more)



axios.all(urlArray)

.then(axios.spread(function () {

  let temp = [];

  for (let i = 0; i < arguments[i].length; i++)

    temp.push(arguments[i].data);

}));

where arguments will contain the callback responses sent by axios. The problem is that arguments contains the given string urls instead of the actual responses. How can I resolve this problem?

You somewhere will need to make the actual requests. And then don't use spread but only then to receive the array of results:

let urlArray = [] // unknown # of urls (1 or more)



let promiseArray = urlArray.map(url => axios.get(url)); // or whatever

axios.all(promiseArray)

.then(function(results) {

  let temp = results.map(r => r.data);

  …

});
