Subscribing to Data
Understand how to subscribe to data collections in a Meteor.js application by ensuring collections exist and are published to the client. Learn to use the useTracker hook in React to manage subscriptions and update the user interface reactively as data changes.
Before we can subscribe to a collection, the collection should exist, and it should be published to the client where we can subscribe to it.
The application below describes how we can subscribe to a collection.
