NodeJS package manager
The NodeJS package manager is npm. npm can install modules globally and locally. Supporting tools like ‘mocha’ for testing and ‘typings’ for TypeScript support are good candidates to install globally. Do keep track though of your globally installed modules since if you want to reproduce your environment somewhere else, these modules could be dependencies (especially in your build process). You can configure local dependencies in a package.json file. When you do a ‘npm install’, modules mentioned in that file are installed locally in the node_modules folder of your project. If you want to also update the package.json, you can do ‘npm install –save’. This allows you to easily update versions of modules. When your node_modules directory is corrupt because you for example interrupted a module download, you can just remove the node_modules directory and rebuild it from the package.json file.
