Many of the UI components within the sample project rely on JSON requests to communicate with the server. Take a look at "src/modules/sampleModule1/departments/viewmodel.js". Inside the 'initialize' method, you will find:
$.getJSON(moduleContext.getSettings().urls.departments, function(result) {
self.allItems(result);
});
In this code snippet, "moduleContext.getSettings().urls.departments" represents the URL that points to a server script returning JSON data. The second parameter is a callback function used to process the response. Since there are no actual server scripts available in the samples, we simulate them using simple JSON files located in the 'server' directory. For instance, the request may target "/server/departments.txt"
