I have a Meteor app and would like to upload data (from csv) to a meteor collection.

I have found:

I've solved this problem in the past using this gist of mine, together with this code (using the jquery-csv plugin to parse the csv data). This is done on the client side and is independent of using iron-router or not. It would be fairly straightforward to move the insertion code into a Meteor method, uploading the csv file first and then parsing and inserting the data on the server. I've tried that, too, but didn't see any performance improvement.

$(document).ready(function() {
    var dd = new dragAndDrop({
        onComplete: function(files) {
            for (var i = 0; i < files.length; i++) {
                // Only process csv files.
                if (!f.type.match('text/csv')) {
                    continue;
                }
                var reader = new FileReader();
                reader.onloadend = function(event) {
                    var all = $.csv.toObjects(event.target.result);
                    // do something with file content
                    _.each(all, function(entry) { 
                         Items.insert(entry);
                    });
                }
             }
        }
     });

     dd.add('upload-div'); // add to an existing div, turning it into a drop container
});

Beware though that if you are inserting a lot of entries, then you are better off turning all reactive rerendering off for a while, until all of them are inserted. Otherwise, both node on the server and the browser tab will get really slow. See my suggested solution here: Meteor's subscription and sync are slow
