Utilizing Axios spread() for handling an indefinite amount of callback parameters

I'm facing a challenge in processing multiple AJAX requests using axios. The goal is to handle an unknown number of requests (1 or more) and manage their responses effectively. Here's what I have so far:

let urlArray = [] // dynamic array of URLs

axios.all(urlArray)
.then(axios.spread(function () {
  let temp = [];
  for (let i = 0; i < arguments[i].length; i++)
    temp.push(arguments[i].data);
}));

The issue lies in the fact that the arguments variable contains the string URLs instead of the actual response data. How can I overcome this obstacle?

Answer №1

At some point, you will need to send out the actual requests. Avoid using spread and opt for only using then to retrieve the array of results:

const urlList = [] // an unknown number of URLs (could be 1 or more)

const promiseArray = urlList.map(url => axios.get(url)); // or any other method
axios.all(promiseArray)
.then(function(results) {
  let temporary = results.map(r => r.data);
  …
});
