Package management via NPM

Truffle comes with npm integration by default and is aware of the node_modules directory in your project, if it exists. This means that you can use and distribute contracts or libraries via npm, making your code available to others and other's code available to you. You can also have a package.json file in your project. You can simply install any npm package in your project and import it in any of the JavaScript files, but it would be called a truffle package only if it contains the two directories mentioned earlier. Installing an npm package in a truffle project is the same as installing an npm package in any Node.js app.
