When setting up a modern JavaScript app, we find ourselves trudging through the land of infinite configuration. Poi offers us an option of zero-configuration by providing sane defaults and hiding them away until you need to tweak a change to suit your needs.

Poi can easily launch an `index.js` file simply by running the `poi` command. This will launch a dev-server and automatically reload whenever you make changes. You can also `npm install` any package you need and `import` it right away.
