Example of a pageRange filter that can be used with FalcorJS to handle a range of values.

falcorPageRange.js

function pageRangeFilterProvider() {
  return function pageRangeFilter(itemCount, currentPage, pageSize) {
    itemCount = itemCount || 0; // The 'length' of the collection
    currentPage = currentPage || 1; // The current page number being viewed
    pageSize = pageSize || 5; // The size of each page
    const range = [];
    for (var x = (currentPage - 1) * pageSize; x < currentPage * pageSize && x < itemCount; x++) {
      range.push(x);
    }
    return range;
  };
}

angular.module('falcorExample')
  .filter('pageRange', pageRangeFilterProvider);
