 **It seems unwieldy to import URLs everywhere. What if one of the URLs links to
 a subtly different version of a library? Isn't it error prone to maintain URLs
 everywhere in a large project?** The solution is to import and re-export your
-external libraries in a central `package.ts` file (which serves the same purpose
