There are multiple ways to download and save a file to the local filesystem in Node. You can either use the built-in modules like fs and https or 3rd party open-source libraries.
The file could be anything: a PDF file, an image, or a simple text file. The fs module grants you access to the filesystem to read and write files in Node. The source code at the end of this post will cover all of APIs including upload files. You can find the complete source code for this tutorial on Github.

I'd like to add one using yet another native NodeJS module that supports either the http or https protocol: Solution I've referenced the official NodeJS API, as well as some of the other answers on this question for something I'm doing.

Because http2 improves framing; adding binary compression, the ability to push from server to client, and simultaneous connections - it is absolutely required that both server and client know the implementation this allows abstraction of implementation from the application too.
Good news is that all major browsers have supported http2 since about - and Node as a client does too. Node, Nginx, and Apache offer it server side - so most use cases are covered.
Its a vast improvement. Thanks for the reply Rik — Neil. Without library it could be buggy just to point out. Here my suggestion: Call system tool like wget or curl use some tool like node-wget-promise which also very simple to use.
