Virtual Scrolling alternative to ngRepeat

Intended as a replacement for ng-repeat for large collections of data and contains different solutions to the problem.


The module was originally developed as a proof of concept but has matured into a useable component. It isn't the ideal solution to the performance issues of large ng-repeat instances, but it does work as a drop-in replacement (with some caveats).

It started because I needed to display log messages and I didn't want to use paging. There were some excellent alternatives including some wrappers of jQuery grids, but nothing was using the ng-repeat pattern. I wrote a couple of articles explaining myself as I went along:

There should be an online demo here:


Whether you build the component, copy the raw source or use bower (see below), the end result should be included in your page and the module sf.virtualScroll included as a dependency:

Then use the directive sf-virtual-scroll just as you would use ng-repeat.

If you want to expose the scroll postion (to simulate an atEnd event for example), use ng-model and you have access to the scroll properties.

Check out the examples in the demo folder for all the details.


First up, the obligatory warning: virtual scrolling is usually the wrong approach. If you want to display really large lists, your users will probably not thank you for it: filtering can be a more friendly way to tame the data. Or if you have performance problems with angular bindings, one of the "bind-once" implementation may make more sense.

Tables are problematic. It is possible to use sf-virtual-repeat in a <tr> to create table rows, but you have to be very careful about your CSS.

The element having the sf-virtual-repeat needs to be contained within an element suitable for use as a viewport. This suitability is the main difficulty as the viewport must contain a single element (and no text) and this contained element must be explicitly sizable. So a table will need 2 parent divs for example.

The collection must be an array (not an object) and the array must not change identity - that is, the value on the scope must remain the same and you should push, pop, splice etc. rather than re-assigning to the scope variable. This is a limitiation that might be removed in future versions, but for now it's a consequence of watching the collection lightly.

Using the component

For use with bower, there is a separate repo containing just the built artifacts here: angular-virtual-scroll-bower. You can add the component to your project with:

Or by adding a line to your component.json file.

If you are using grunt for your build, consider using a plugin like bowerful.
