Error using Miso.Dataset with URL on node.js

[Deleted user]

Miso.Dataset works great within the browser, using on Node.js for first time and getting an error. Presumably a newbie error, but looks like the one reported in #193.

Specifically it appears global is undefined. Was able to create the issue in a new project:

• express --sessions miso_test
• npm install miso.dataset --save
• npm install
• then add following lines at end of app.js:

var Miso = require("miso.dataset");


// this works fine
//var ds = new Miso.Dataset({
//  data:  [
//  { color : "red",   r : 255, g : 0,   b : 0   },
//  { color : "blue",  r : 0,   g : 0,   b : 255 },
//  { color : "green", r : 0,   g : 255, b : 0   }
//]
//});

// this fails on fetch
var ds = new Miso.Dataset({
      url: 'data/MST.csv',
      delimiter: ','
    }
);

ds.fetch({
  success : function() {
    console.log("Available Columns:" + this.columnNames());
    console.log("There are " + this.length + " rows");
  }
});

Reading files and parsing CSV files is a specialty in itself, so delegated that part to node-csv, and all works well.

var Miso = require("miso.dataset");
var csv = require('csv');

csv()
    .from.options({columns: true})
    .from.path(__dirname+'/../public/data/MST.csv', { delimiter: ',', escape: '"' })
    .to.array( function(data){
      var ds = new Miso.Dataset({
        data: data
      });
      ds.fetch({
        success : function() {
          console.log("Dataset Ready. Columns: " + this.columnNames());
          console.log("There are " + this.length + " rows");
        }
      });
    });
