Sometimes, you only want to download RPM packages without installing them. This is now super easy with DNF.
If you remember Yum, you had to resolve to installing a
yum-plugin-downloadonly plugin or a separate tool to be able to download them for inspection.
With DNF on the latest Fedora and CentOS 8, you can just run
$ sudo dnf download ruby (1/2): ruby-2.7.2-135.fc32.i686.rpm 133 kB/s | 41 kB 00:00 (2/2): ruby-2.7.2-135.fc32.x86_64.rpm 133 kB/s | 40 kB 00:00
As you can see, I am not specifying the architecture, so I got both. They were downloaded to the current working directory, which is also convenient.
There is also
dnf download --resolve which pulls dependent packages as well:
$ sudo dnf download --resolve ruby (1/6): gdbm-libs-1.18.1-3.fc32.i686.rpm 171 kB/s | 57 kB 00:00 (2/6): ruby-2.7.2-135.fc32.x86_64.rpm 73 kB/s | 40 kB 00:00 (3/6): ruby-2.7.2-135.fc32.i686.rpm 72 kB/s | 41 kB 00:00 (4/6): readline-8.0-4.fc32.i686.rpm 449 kB/s | 210 kB 00:00 (5/6): ruby-libs-2.7.2-135.fc32.x86_64.rpm 300 kB/s | 3.2 MB 00:10 (6/6): ruby-libs-2.7.2-135.fc32.i686.rpm 267 kB/s | 3.3 MB 00:12
