Retrieve Popular Documents Programmatically In SharePoint using JSOM and REST API

Introduction

The popular documents can be viewed manually from the document libraries withthe popular items tab. In this article, you will learn how to fetch popular documents based on view counts using JSOM and REST API. This will be applicable for all SharePoint platforms.

Prerequisite

You have to enable the reporting feature under site collection features in the site to see the popular documents. This data can be retrieved using search queries. Basically this is part of SharePoint analytics.

Using JSOM

1. Set and get the necessary context. Using the context, initiate the keyword query function.
   
   1. var searchContext = new SP.ClientContext();
   2. var searchQuery = new Microsoft.SharePoint.Client.Search.Query.KeywordQuery(searchContext);
2. The results can be retrieved using multiple query filters. In this case, I am using path variable to filter the data. This helps us in getting results for one particular library. Multiple document library data can also be viewed by setting the filters with 'and' parameter. Set the query text as below.
   
   1. searchQuery.set_queryText("path:http://siteurl/Documents”)
3. The following syntax helps us in executing the query against the search server by initializing a SearchExecutor instance.
   
   1. var searchExecutor = new Microsoft.SharePoint.Client.Search.Query.SearchExecutor(searchContext);
4. Initialize the results and execute the request.
   
   1. searchRes = searchExecutor.executeQuery(searchQuery);
   2. searchContext.executeQueryAsync(SearchResults, QueryFailed);
5. In the success function, expand the result set (searchRes) to see the document results. The following code snippet shows you to parse the search results.
   1. var resultSet = searchRes.m_value.ResultTables[0].ResultRows;
   2. var popularDocs = new Array();
   3. for(var i = 0; i < resultSet.length; i++)
   4. {
   5. popularDocs[i] = [resultSet[i].Title,resultSet[i].ViewsLifeTime];
   6. }
6. Then sort the result set on descending order based on the view count using the below logic.
   
   1. function Sort(a, b) {
   2. return (a[1] > b[1] ? -1 : (a[1] < b[1] ? 1 : 0));
   3. }
7. Now popularDocs array will have the result set sorted based on the view count.
   
   1. popularDocs.sort(Sort);
