Why are frontend frameworks in NPM?

When I’m looking at some github projects and tutorials I look at the package.json file and see frontend frameworks listed as the dependencies quite a lot. I don’t get it. I thought Node was backend? My understanding is that to install frontend frameworks you dl them directly from their website or github or use a CDN then link them in your pages - all this has nothing to do with Node.

Even if I did install a framework through Node doesn’t it save it to the node_modules folder? There must be a reason for it as I’ve seen a lot of projects list them in their package.json file. Can anyone explain this to me?

NodeJS is not only a "server" in the sense that it is a programmable webserver, it is a JavaScript runtime. You can use it to serve webpages, but you can also use the NodeJS server as a parser / generator for JavaScript (meaning: reading and writing files on the system). If you use one of the frontend frameworks like react and angular, you install the packages just to get their sourcecode and not to actually run the code on the server. Then you use a bundler like webpack to turn the code you've written and the code from the modules into one (or multiple) large chunks of minified frontend code. You can usually find those generated files inside the /dist or /build folder. Now to get these files to clients, you can use NodeJS as a server too, serving the files to the clients. That way, the packages "installed" on your server end up on your client.
