Now it returns the value directly (or throws an error). Perfect for server-side methods!

Meteor 3 has removed Fibers. wrapAsync still works, but you should migrate to native async/await :

Wrap the function once outside the method to avoid re-wrapping on every call.

If you're working with asynchronous code in Meteor (especially on the server), you've likely encountered Meteor.wrapAsync .

// Without wrapAsync (callback style) function fetchData(callback) { setTimeout(() => callback(null, { user: 'alice' }), 100); } // With wrapAsync const syncFetch = Meteor.wrapAsync(fetchData); const result = syncFetch(); // Blocks until done console.log(result.user); // 'alice'

If you're still using Meteor.wrapAsync , you're writing legacy code (but it works!). Here's the modern take:
