In my current setup, I have a "requests" collection and I have successfully set up publications on the server side and subscriptions on the client side. My question is, how can I effectively handle new records in MongoDB? Specifically, I would like to receive any new records added to the "requests" collection on the client side so I can perform certain actions. Can you provide guidance on how to achieve this?
Depending on the action you wish to take.
A simple solution is to utilize the Tracker#autorun function.
Tracker.autorun(function() {
MyCollection.find()
// Implement action here
}
This will automatically re-run when there are changes in your collection.
If your focus is solely on the new documents, you can opt for Mongo.Cursor#observeChanges.
MyCollection.find().observeChanges({
added(id, fields) {
//perform desired action
},
changed(id, fields) {
//perform desired action
},
removed(id) {
//perform desired action
},
});
