Integrating MongoDb with Angular: A Beginner's Guide

I am facing an issue with accessing MongoDB in my IONIC project. Despite using a controller and having functions available in the template, I can't seem to connect to mongoDB. I am unsure of how to resolve this problem.

$scope.InsertUser = function(){
    user = $("#NameId").val();
    db.users.insert(user);
}

Upon checking the log, it states "db is not defined". While I understand that this cannot be used on the client side, I am puzzled about where the server side should be located. Here's the directory tree structure of my project:

enter image description here

I have searched through various videos and tutorials, but I still can't figure out where to declare my collections or place my CRUD methods such as: db.users.insert(user);

If anyone has insights on how to handle this issue, your help would be greatly appreciated!

To successfully implement this, it is important to remember that all declarations should be done on the server side. Depending on which server side you are using, my preference lies with the Play Framework in conjunction with Java. What I typically do is initiate a GET request from Angular utilizing RestAngular to communicate with a function on the server side. Here's an example: Client Side:

return: function(){
    restAngular.all("/get").get().then(function(result){
        $scope.array = result;
    })
}
(the GET request retrieves its response from this function) Server Side:
private final MongoClient mongoClient = new MongoClient();
private final MongoDatabase db = mongoClient.getDatabase("test");
private final MongoCollection<Document> usersCollection = MongoDatabase.getCollection("posts");

public static Result getResult(){
    return usersCollection.find().sort(descending("date"))
                              .limit(limit)
                              .into(new ArrayList<Document>());
}
This serves as a basic example of how to execute it with Angular on the client side and Java on the server side. For additional assistance, feel free to leave a comment below.
