Usage
Reverse Pagination
The best way that I have found to get the latest objects in the database is to use $sort like so:
app.service("messages").find({
query: {
$limit: 10,
$sort: {
createdAt: -1
}
}
}).then(res => {
const latestData = res.data.reverse();

I had an issue where the client authenticated and I received the authentication token but when I use a service it says that I'm not authenticated.
The solution was to ensure that the client setup the transport before the authentication.
