All the source javascript is in src/*.js. We're using ES6 code with modules, transpiled via Babel and Rollup, to create our library. ESLint is used to keep things nice and clean along the way.
Make sure you've run npm install to get all the node_modules
that we need. You'll also need to install Rollup
globally (npm install -g rollup).
Then run npm run dev to kick off a watch process and local web
server. As you edit source files, they'll be transpiled
automatically and you can reload/run things in the browser.
