Drag and drop function is not working in chromedriver using selenium webdriver and Node js for Test automation

First of all, you forgot the build() method.
Second of all, inspect the html code and find if your drag&drop is into Iframe tag.
If it is, then you need to switch to that Iframe.

So:

driver.switchTo().frame(driver.findElement(By.xpath("PutYourXpathIframe")));  

Actions a = new Actions(driver);
WebElement source = driver.findElement(By.id("PutYourSourceId"));
WebElement target = driver.findElement(By.id("PutyourTargerId"));
a.dragAndDrop(source,target).build().perform();

In the end you may want to switch back to default content:

driver.switchTo().defaultContent();

As a workaround could you use the following?:

 browser.actions()
    .mouseDown(element1) //optionally
    .mouseMove(source)
    .mouseMove(destination)
    .mouseUp()
    .perform();

This page has a good example of how to do this.

var assert = require(‘assert’);
var webdriver = require(‘selenium-webdriver’),
By = webdriver.By,
until = webdriver.until;

var chrome = require(“selenium-webdriver/chrome”);

var options = new chrome.Options();
options.addArguments(“start-maximized”);
options.addArguments(“disable-popup-blocking”);
options.addArguments(“test-type”); 
var driver = new webdriver.Builder().
withCapabilities(options.toCapabilities()).build();

driver.get(‘http://www.softpost.org/selenium-test-page/’);
var e3 = driver.findElement(By.tagName(‘select’));

//You can use ActionSequence class to perform actions in selenium

new webdriver.ActionSequence(driver).
keyDown(webdriver.Key.SHIFT).
click(e3).
//dragAndDrop(element3, element4).
keyUp(webdriver.Key.SHIFT).
perform();

//In the same way, you can perform below actions.
//sendKeys, mouseUp , mouseMove, mouseDown, dragAndDrop, doubleClick

driver.sleep(5000);

driver.quit();
//Similarly we can also do touch actions on mobile phones`
