Backbone.LocalStorage is not a function

Question

I am using backbone localstorage plugin however, it is giving me following error.

Uncaught TypeError: Backbone.LocalStorage is not a function

I am using it in following way in my collection

var TodoList = Backbone.Collection.extend({
    model: TodoModel,
    localStorage: new Backbone.LocalStorage('todos-backbone')
});

How can I solve this problem?

I import them in index.html

<script src="node_modules/jquery/dist/jquery.min.js"></script>
<script src="node_modules/backbone/node_modules/underscore/underscore-min.js"></script>

I think you are confusing https://github.com/jeromegn/Backbone.localStorage and https://github.com/robmoorman/backbone-localstorage. Backbone.LocalStorage is a function only in the former while the one you have included is used like this:

var TodoList = Backbone.Collection.extend({
    model: TodoModel,
    localStorage: true
});
