JavaScript Fetch API

[None None None]

Is the Fetch API supported in Qml? (Qt 5 / Qt 6) https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API

This code example gives an error when executed in Qml:

const fetchPromise = fetch("https://ghibliapi.herokuapp.com/people");
fetchPromise.then(response => {
  return response.json();
}).then(people => {
  console.log(people);
});

(Via: https://medium.com/@armando_amador/how-to-make-http-requests-using-fetch-api-and-promises-b0ca7370a444)

The error message:

qrc:/main.qml:49: ReferenceError: fetch is not defined

Tried with Qt 5.15.2 and 6.3.

Never tried if it is working, as I still use my old helper method and pass a function into the callback:

function doRequest(url, method, callback) {
    var xhr = new XMLHttpRequest()
    xhr.onreadystatechange = (function (myxhr) {
        return function () {
            if (xhr.readyState === XMLHttpRequest.DONE)
                callback(myxhr)
        }
    })(xhr)
    xhr.open(method, url, true)
    xhr.send('')
}
