You can just use underscore.js, which comes with Meteor – should be fine for the suggested use case. You might run into performance problems if you try this on a vast data set or run it repeatedly, but it should be adequate for common-or-garden usage:
var distinctEntries = _.uniq(Collection.find({}, {
sort: {myField: 1}, fields: {myField: true}
}).fetch().map(function(x) {
return x.myField;
}), true);
That will return the distinct entries in myField
for all documents in Collection
. Apologies if the one-liner looks a bit unwieldy; the sort
and fields
options and the true
flag are just to make it more efficient.
