How to Reference JavsScript and CSS Files for Entire Application

Kim Mertens recently posted the following question today on Twitter: Where to put JS-file that has to be loaded on every page in #orclapex 5.0? Tried “Global Page - Static region” but jQuery isn’t loaded yet

The answer isn’t as straight forward as you think. Most people are used to referencing web files (JavaScript and CSS files) on Page 0 from legacy APEX 4. As Kim hinted at in his question this isn’t always the best thing to do.

In APEX 5 there’s a specific area dedicated to reference custom web files. It’s not the easiest thing to find at first (it takes me a few tries to find it sometimes if I haven’t used it in a while).
