AngularJS 1.8: Problems with sorting filter and binding to a large dataset in a table
I'm optimizing some code but I'm experiencing performance optimization when trying to use the built-in `orderBy` filter in AngularJS 1.8 with a large dataset that I bind to a table. The table displays around 10,000 rows, and when I attempt to sort the data using the `orderBy` filter, the UI freezes temporarily, making it unusable for end-users. I tried implementing pagination to improve performance, but I'm still working with important delays. Here’s the relevant part of my HTML and JavaScript: ```html <table> <thead> <tr> <th ng-click="sort('name')">Name</th> <th ng-click="sort('age')">Age</th> <th ng-click="sort('email')">Email</th> </tr> </thead> <tbody> <tr ng-repeat="user in users | orderBy:sortField:reverseSort"> <td>{{ user.name }}</td> <td>{{ user.age }}</td> <td>{{ user.email }}</td> </tr> </tbody> </table> ``` ```javascript $scope.users = largeDataset; // Assume this is an array of 10,000+ user objects $scope.sortField = 'name'; $scope.reverseSort = false; $scope.sort = function(field) { $scope.reverseSort = ($scope.sortField === field) ? !$scope.reverseSort : false; $scope.sortField = field; }; ``` Even with pagination in place, the sorting operation still seems to process all 10,000 items, which causes noticeable delays. I tried using the `track by` clause in the `ng-repeat`, but it didn’t help. I also looked into using `ng-if` to limit the number of items displayed at a time, but that didn't seem to align with the functionality I need. Does anyone have suggestions on optimizing the sorting process or an alternative approach to handle large datasets more efficiently in AngularJS? Any help would be greatly appreciated! Could this be a known issue? What am I doing wrong?
