Scrolling large sets using AngularJS that actually work on mobile devices can be quite a challenge! What this directive allows you to do is to create a scroll view over a large set of data by only requesting a window of the data that is actually visible.

This directive only adds a minimal amount of elements to the DOM so it works well on mobile devices.

This directive here is based on iScroll which was slighly modified. iScroll is built into this directive due to the changes that have been made to it.

You can use it as follows in your view:

 <infinite-list 
        request-data="getData" 
        row-template="'<p>The item: {{item}}</p>'" />

Now in your controller you need a function that fetches the data:

 $scope.getData = function(offset, size) {
    var def = $q.defer();
    // This is the actual data format we need to return..
    var data = {
      limits {
        start : offset,
        end   : offset + size,
        total : 10000
      },
      items : []
    };
    for(var i = offset; i < Math.min(offset + size, 10000); i++) {
          data.items.push('Element: ' + i);
    }
    def.resolve(data);
    return def.promise;
  };

You can also use row-template-url if your template is stored in a file somewhere. You can also watch a variable, which will trigger a refresh. You can pass in iScroll options using the options attribute. For example:

<infinite-list request-data="getSetData" 
               row-template="'<p>[{{item}}]</p>'" 
               options="iscrollOptions" 
               refresh="'set.size, set.order'"  />

Note! Your template should have a fixed height! Otherwise the scroller will not work! Note! Your template will be called with scope.item === undefined in case the item is not yet retrieved

Now you might have a scenario where you would like to show data that is grouped, and want to have a Grouped By header introduced in between the normal rows. You can accomplish this by setting the header template as well. For example:

<infinite-list request-data="getGroupData" header-template="'<H1>{{item}}!</H1>'" row-template="'<p>[{{item}}]</p>'" />

 $scope.getData = function(offset, size) {
    var def = $q.defer();
    // This is the actual data format we need to return..
    var data = {
      limits {
        start : offset,
        end   : offset + size,
        total : 10000
      },
      groupBy : [
          { item : 'Group 1', offset : 0 },
          { item : 'Group 2', offset : 10 },
          { item : 'Another group', offset : 25 },
          { item : 'Groups etc..', offset : 100 },
      ],
      items : []
    };
    for(var i = offset; i < Math.min(offset + size, 10000); i++) {
          data.items.push('Element: ' + i);
    }
    def.resolve(data);
    return def.promise;
  };

This will result in a Header row being rendered at the given offset position. So at offset 0 your header template would be bound to item : 'Group 1'
