Exploring data visualization through object classification in Angular JS

I am facing a scenario where my API returns a single JSON Object if there is only one element in the response, and an array of objects if there are more than one elements. This poses a challenge as I need to handle both cases without changing the JSON structure.

While I can use the javascript controller to always treat the response as an array and loop through it using ng-repeat, this approach also affects properties within the JSON object. As such, I am seeking a solution within Angular 1.x that allows me to display the data seamlessly, regardless of whether it is a single object or an array of objects.

Given that I may need to update the record via the API, maintaining the current JSON structure is crucial. Is there a straightforward way in Angular to accomplish this?

Answer №1

Unfortunately, there is no straightforward method to accomplish that task. A more efficient approach would be converting the single object into an array within your controller:

retrieveData(...).then(result =>  result.length ? result : [result])
                 .then(dataArray => $scope.data = dataArray);

Answer №2

In order to streamline your view logic, it might be necessary to make adjustments to the response being received. Otherwise, you could find yourself having to conduct numerous case-by-case checks throughout your code.

One approach could be to introduce a service layer that acts as an intermediary between your controllers and the API. This layer can interpret the JSON data by recursively iterating through the response and encapsulating individual objects within arrays when fetching data.

Likewise, when sending data back to the API, the service layer could reverse this process by removing array wrappers from singular objects before submission.
