Updates the package.json file in your project, if needed.When you install (or uninstall, or update) a package, npm does most, if not all, of the following four things: That’s not part of Sass… right? Well, that’s correct, but there’s a very good explanation why those new items were generated in the project folder. What are these!? We asked npm to install Sass, not all this stuff. Oddly, however, we do see a three new items in the project folder: two JSON files named package.json and package-lock.json, plus one entirely new node_modules folder. Once we’ve run the install command, you may notice that you do not see anything named “sass” in the project folder as you might expect. (This is why you see that npm added 16 packages and audited a total of 17 npm packages, instead of the Sass package alone-it, too, has dependencies!) If it finds that package (which it does), npm installs it to the project in an automatically generated node_modules folder (more on this in a bit) located in the project root folder, including everything the package needs to run. What’s happening behind the scenes there is that npm tries to find a package named sass in the npm package registry. That’s all you need! Type that and npm goes straight to work: For example, the Node package for Sass is simply called “sass” which means we can add to a project like this (just be sure you’re in a new folder you created for this little project first): npm install sass We can install our very first package with the npm install command (or npm i for short), followed by the name of the packages we want to add to our project.

How the Heck Do You Install an Existing npm Project?.How the Heck Do You Install npm Packages? (You are here!).Next up in this beginner’s guide to npm is likely why you’re here in the first place: installing npm packages. In the previous chapter, we even installed Node and npm while getting acquainted with Node Version Manager, or nvm. By now, you’re becoming quite knowledgeable with npm! So far, we’ve broken down the three letters in “npm” to gain a better understand of Node and package managers.
