How to use projection?

I want to use like this const projection = { items: { $slice: -5 } } ProjectModel.model.find({}, projection);

You should use options object

const options = {
    page: 1,
    limit: 10,
    projection: { items: { $slice: -5 } },
    sort: { _id: -1 }
};

Model.paginate({}, options);

You could do it like this:

const options = {
    page: 1,
    limit: 10,
    projection: { items: { $slice: -5 } },
    sort: { "items.price": -1 }
};

Model.paginate({}, options);
