How to list all users belongs to particular user store using jaggery?

We can list all users belongs to particular user store using jaggery. To achieve this, create a directory(ListUser) inside "<BPS>/repository/deployment/server/jaggeryapps" and then create a jaggery file(listUser.jag) inside a newly created folder. In this example, I used WSO2 BPS to test this sample.

Add the following content into listUser.jag file.

<%
var carbon = require('carbon');
var tenantId = -1234;
var url = 'https://<HOSTNAME>:9443/admin/services/';
var server = new carbon.server.Server(url);
var userManager = new carbon.user.UserManager(server, tenantId);
 
print(userManager.getUserListOfRole("ROLE"));
%>

Here, you need to change the "HOSTNAME" and "ROLE" according to your config. Please find the sample listUser.jag blow, where my "HOSTNAME" is localhost and user "ROLE" is WSO2USERSTORE/clerk.

<%
var carbon = require('carbon');
var tenantId = -1234;
var url = 'https://localhost:9443/admin/services/';
var server = new carbon.server.Server(url);
var userManager = new carbon.user.UserManager(server, tenantId);
 
print(userManager.getUserListOfRole("WSO2USERSTORE/clerk"));
%>

Once you add "listUser.jag" file, go to the browser and enter the URL https://<HOSTNAME>:9443/ListUser/listUser.jag where <HOSTNAME> is same as in .jag file.
