This is a buildpack for Node.js / io.js apps, powered by npm.

The buildpack will use npm to install your dependencies, vendoring a copy of the Node.js / io.js into your web container.

This is our default buildpack for Node.js / io.js applications. In case you want to introduce custom changes, fork the buildpack, apply changes and test them via the custom buildpack feature.

You can specify the versions of Node.js / io.js and npm your application requires using package.json.
