Endless loading with Restangular

Question

Endless loading with Restangular

Currently, I am using a Restangular collection which is functioning perfectly:

$scope.threads = Restangular.all('thread').getList({ limit: 10, offset: 0 }).$object;

However, my goal is to enhance the functionality by implementing a feature where additional thread models can be loaded when the user triggers it, either through scrolling to the bottom of the list or by clicking a 'Load more' button. Whenever I call .getList() again with a new offset value, it simply replaces the entire collection:

$scope.threads.getList({ limit: 10, offset: 10 });

Is there a solution available that allows the newly returned models to be added or pushed onto the existing array instead of replacing them entirely?

If you want to optimize performance, consider using Promises supported by Restangular. Once the data is received, you can utilize Array.push() method to add the results to $scope.threads

Here's an example code snippet:

$scope.threads = Restangular.all('thread').getList({ limit: 10, offset: 0 }).then(function(resultThreads){
$scope.threads.push(resultThreads);
});

To ensure smooth loading of additional data, keep track of your offset for fetching the next set either upon scrolling or clicking 'Load more'. In scenarios involving a large dataset, it might be beneficial to remove items from the beginning of the array while adding new ones at the end.
