How to get listitem counts via rest api

Question

I tried the below to get all item count of a list but it doesn't work

/_api/Web/Lists/getByTitle('<list title>')?$select=ItemCount,Items&$expand=Items

Any ideas how i can get an itemcount as well as retrieving the fields in my select? How can i also retrieve itemCount with filtering?

Thanks in Advance

Answer 1

Use REST API to get items you need, then get no.of items using data.d.results.length.

function getItems(url) {    
    return $.ajax({
        url: _spPageContextInfo.webAbsoluteUrl + url,
        type: "GET",
        headers: {
            "accept": "application/json;odata=verbose",
        }
    });
}

getItems( "/_api/Web/Lists/GetByTitle('<list title>')/Items" ).done(function(data){

    var numofItems = data.d.results.length;
     data.d.results.forEach(function(item){ 
        console.log( item.ID);
     });
});

You could use the rest API below as mentioned.

/_api/web/lists/getbytitle('<list title>')/ItemCount

You will get item count of any list or library

you have one more option to retrieve both

You could construct the following query to return items and items count:

/_api/Web/Lists/getByTitle('<list title>')?$select=ItemCount,Items&$expand=Items

In success function you could write the below code to get

 var itemsCount = data.d.ItemCount;
    var items = data.d.Items.results;

It is better to use:

"/_api/web/lists/getbytitle('<list title>')/ItemCount"

instead of:

"/_api/Web/Lists/GetByTitle('<list title>')/Items"

because "/ItemCount" is faster with quick response.
