Issue with AngularJs: $http post only posting single item to collection inside a for loop

I have a collection that requires me to post multiple items in a for loop. Below is the code snippet:

            for(i = 0; i < 28; i++) {
                var request = $http({
                    method: "post",
                    url: "/students",
                    data: {
                        studentName: "Student",
                        answerImage: "image", 
                        questionPrompt: 1
                    }
                }).then(function successCallback(response) {
                }, function errorCallback(response) {
                    console.log(response);
                });
              }

Despite trying several times, I am facing an issue where it only posts around 20-23 items out of the expected 28. The data fields seem fine, but I keep getting this error response in the console:

 Object {data: null, status: -1, config: Object, statusText: ""} 

I'm unsure about the next steps to take. In my actual application, I will need to post approximately 200 items like this. Could it be a timing out problem?

Thank you!

Answer №1

It's important to consider that you may encounter a timeout issue due to the browser limiting concurrent requests to the same domain. The standard limit is usually around 6, but this can vary between different browsers.

Sending over 200 HTTP requests simultaneously can significantly slow down your application's performance.

A preferable strategy would be to adjust your endpoint to accept a collection of data or create a new endpoint for this purpose. Sending a single request with 200 objects will improve efficiency compared to sending multiple individual requests.
