building from source

npm run buildtesting
npm install
npm test [optional seed]The test outputs the seed it's using at the top, which you can
pass back into npm test [seed] to replicate behaviour.
include (browser)
Include dist/drawpoint.js in a script tag and use drawpoint as the global namespace containing all the functions.
<html>
<head>
<meta charset="UTF-8">
<script src="./drawpoint.js"></script>
</head>
<body>
<canvas id="cv" width="600" height="600" style="border:solid black 2px"></canvas>
<script>
// can use just as a global variable in the browser
// use dp as a shorthand
const dp = drawpoint;
</script>
</body>
</html>include (CommonJS)
Only useful is the source is ultimately used in the browser since that's the only
place where canvas and rendering contexts exist. This would be the case if the
code's passed through browserify or webpack, for example.
const dp = require('drawpoint');include (ES2015 module)
import * as dp from 'drawpoint';
