Given a Ajax request in AngularJS
$http.get("/backend/").success(callback); what is the most effective way to cancel that request if another request is launched (same backend, different parameters for instance).

We can use the AbortController object and the associated AbortSignal with the Fetch API to make cancelable HTTP requests. Once the AbortSignal is sent, the HTTP request is canceled and won't be sent if the cancellation signal is sent before the HTTP request is done.
You can create an interceptor to apply takeUntil operator to every request. Then on route change you will emit event that will cancel all pending requests. Helper service. Hook on route changes somewhere in your app (e.g. onInit in appComponent).
$http is an AngularJS service for reading data from remote servers.
AngularJS includes certain directives which can be used to provide custom behavior on various DOM events, such as click, dblclick, mouseenter etc.
This feature was added to the 1.1.5 release via a timeout parameter:
var canceler = $q.defer(); $http.get('/someUrl', {timeout: canceler.promise}).success(successCallback); // later... canceler.resolve(); // Aborts the $http request if it isn't finished. If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
