In the “An all new Glitch editor” topic, this was listed as one of the new features added in the update:
Better, faster assets overall: Assets in new projects are now cached by Fastly — automatically. We’ll provide a means of migrating existing projects to Fastly shortly. Uploading assets is zippier than ever, and now you can just reference them by a short name, instead of tracking down a full URL.
Because replies in that topic rarely attract any replies, I am asking in this post specifically about the quote, “you can just reference them by a short name”.
How do I do this?
