If your Internet Protocol (IP) address is something like 192.168.1.x, chances are you are in a private network. RFC 1918 specifies a range of IP addresses for networks that are not directly exposed to the Internet. Typically these types of addresses employ Network Address Translation or NAT to route to the external Internet.

gkhays / Download File with Node.md
Created February 27, 2020 17:26
Download a file from a URL using Node.js

Download File from URL

Proof-of-concept to download a file from a URL and save it locally. For example, I may wish to retrieve a JAR file from Nexus.

Uses the http package, which does the basics with raw HTTP protocol support.

Possible update: use request, it is like the Python's requests library. There is a companion package called node-request-progress that tracks download progress. See request-progress on GitHub.

Note: The request package has been deprecated.

Get the path of a running JAR file

The .toURI() method allows you to sidestep issues with special characters.

return new File(MyClass.class.getProtectionDomain().getCodeSource().getLocation()
    .toURI()).getPath();
