How to perform a find and sort on a Meteor collection (using Coffeescript)

I'm new to Meteor and struggling to find any examples of using find and sort on a collection (and specifically using CS).

I seem to have a basic find operation working:

Tasks.find(done: false)

but am struggling to see how to add on a sort query to this? Are there any good examples of these queries? (Even in pure JS)? Many thanks.

You can see the documentation for find here. If you just search the docs for sort: you'll find several examples. Using your code above, you could sort your completed tasks by completedAt like so:

Tasks.find {done: true}, sort: completedAt: -1

A brief primer-by-example in JS:

Tasks.find({done: false}, {order: {status: 1}});

would sort by status ascending.

Tasks.find({done: false},{order: {status: 1, assignee: -1}});

will sort by status ascending then assignee descending.

Tasks.find({done: false},{order: {status: 1}, limit: 5});

will limit the results to the first 5.

For CS, you could define the options object itself as:

options = 
  sort:
    status: 1

and then do

Tasks.find(done: false, options)
