Hi there, we encourage authors to share their entire posts here on DEV, rather than mostly pointing to an external link. Doing so helps ensure that readers don’t have to jump around to too many different pages, and it helps focus the conversation right here in the comments section.

If you choose to do so, you also have the option to add a canonical URL directly to your post.
