Creating a single html file (like main.html)
Creating a javascript file for each drawing I do (like drawing1.js)
Installing the package in that directory (npm install artofmo)
Running a local server in the directory those files live in (Webserver for Chrome)
Visiting a url like http://localhost:8887/main.html?file=drawing1

My directory ends up looking like:

mo-v0-0-5
- main.html
- drawing1.js
- artofmo - the node package, versioned according to parent folder
- assets - images and whatnot

You don't need to separate main.html from drawing1.js, but it makes it a lot easier to create many drawings without duplicating the boilerplate html.

`main.html`

      let searchParams = new URLSearchParams(window.location.search);
      let file = searchParams.get('file');

      import(`./${file}.js`).then(module => {
        var {run} = module.default;

        run();
      });
    </script>
  </head>
  <body>
    <div id="mo-container">

`drawing1.js`

var run = () => {
  mo.colors.fetch({samples: [[58, 119, 108]], count: 5}).then(colors => {
    mo.ui.init.basic({
      backgroundColor: '#000',
      containerId: 'mo-container',
      size: mo.lib.canvasSizeFor({dpi: 300, inches: {width: 11 - 6/8, height: 17 - 6/8}, retina: true}),
      overlay: false,
    }).then(({rand, render, canvasView, size}) => {
      var offset = {x: -size.width / 2, y: -size.height / 2};
      var diameter = 12;
      var rows = size.height / diameter;
      var columns = size.width / diameter;
      var radius = diameter / 2;
      var circles = {offset, rows, columns, diameter, size: {width: diameter, height: diameter}};

      _.times(circles.rows, row => {
        _.times(circles.columns, column => {
          var circle = {
            x: _.floor(offset.x + column * diameter + radius),
            y: _.floor(offset.y + row * diameter + radius),
            diameter: diameter + 0.5 - diameter / 8 - rand() * diameter / 2,
            color: _.sample(customColors || colors)
          };

          circle.radius = circle.diameter / 2;

          if (circle.radius % 2 === 0) circle.radius -= 1;

          circle.object = new mo.FabricCanvasObject({
            origin: {x: 'center', y: 'center'},
            shape: 'circle',
            position: circle,
            radius: circle.radius,
            zIndex: 1,
            stroke: circle.color,
            fill: circle.color,
            strokeWidth: 0
          });

          canvasView.add(circle);
        });
      });

      render();
    });
  });
};

export default {run};
