SharePoint Online contains the $batch api endpoint. This will enable multiple requests to be sent in one request to the server. Additional documentation is available here.

Creating Batches

Instead of using the execute method, use the batch method to bulk multiple requests in a single execution to the server. The method properties are similar to the execute method:

  • batch(callback: (value) => void)
  • batch(createFl: boolean)
  • batch(callback: (value) => void, createFl: boolean)

Callback Method

The callback method will be triggered after the request executes.

Create Flag

The create flag will put the request in a new batch request. Each batch request will be executed as a single request to the server, but has a limitation of 100 requests per batch.

Code Example

This code example will first create a demo list, if it doesn’t already exist. We will create items, get the list and delete it in a batch request.

import { SPTypes, Web } from "gd-sprest";

// Method to execute the batch requests
function executeBatchRequests(list) {
    var web = Web();

    // Create 1500 items
    for(let i=1; i<=1500; i++) {
        // Add a new item
            Title: "Batch Item " + i
        // On creation of an item, log to the console
        .batch(function (item) {
            // Log
            console.log("Item '" + item.Title + "' created.");
        }, i%100==0); // Limitation of 100 requests per batch, so this will create 15 batch requests

    // Get the list after the items are created
    web.Lists("BatchList").batch(function (list) {
        // See if the list exists
        if (list.existsFl) {
            // Log
            console.log("List contains " + list.ItemCount + " items.");
        } else {
            // Log
            console.log("Error getting the list.");
    }, true); // Setting true here will create a new batch request

    // Delete the list
    web.Lists("BatchList").delete().batch(function () {
        // Log
        writeToLog("Clean Up", LogType.SubHeader);

        // Log
        writeToLog("List was deleted.", LogType.Info);

    // Execute the requests

// Get the list
    // Exists
    list => {
        // Execute the batch requests
    // Doesn't exist
    () => {
        // Create the list
            BaseTemplate: SPTypes.ListTemplateType.GenericList,
            Title: "BatchList"
        }).execute(list => {
            // Execute the batch requests
