The most popular way to download a file without any dependencies is to use the standard library
open-uri .
Kernel#open is a method that you can use to open files, streams, or processes to read to or write from. For example, you can open a file and read its contents with the following code:

To do so, we first require
open-uri then use the open method to access an image URL. We can then open up a file and write the contents of the image to the file. Open up IRB and try the following:

open-uri like this is not ideal. First up, the above code is not very memory efficient, it loads the entire image into memory and then writes to disk. It also turns out that open-uri has some other quirks. Janko Marohnić discovered a bunch of these issues while working on Shrine. Notably, open-uri :
To solve all of this, Janko created the
Down gem. It allows you to avoid these issues to safely and efficiently download files.
