Question

What is the best way to ensure that a collection is only released when necessary?

Within my application, I have a streamlined public profile that showcases only a portion of the fields stored in my Meteor.users collection. While I understand that I can selectively publish specific fields from the collection, I am concerned about unnecessary data being transmitted to users when they subscribe to it. As a solution, I aim to publish this data on demand, meaning it will only be accessible when requested by the user - for example, upon visiting

/public-profile/425f7834985r79na8syf

.

Answer №1

Create a route that requires a parameter (for example, /profile/:_id)
Ensure your route subscribes to a publication using the provided _id, like this:
```
Meteor.subscribe('getProfile', id);
```

Set up the publication as follows:

Meteor.publish('getProfile', function(id){
  return Meteor.users.find({_id: id}, {fields: {importantField: 1, additionalField: 1}});
});

Keep in mind that even though we anticipate only one document, the publish function returns a cursor and not a single document with findOne().
