ES modules for the modern web

An ES module packaging would allow my app to load the Dropbox SDK dynamically, using now-standard dynamic module imports, which is beneficial since I only need it for certain situations.  I could even use it in a web worker, again loaded dynamically.

I attempted to use the Dropbox SDK and bundle my app using esbuild.  It failed to resolve "crypto" and "utils".  Perhaps this is an issue with your package.json, or perhaps your "module" is just an IIFE that assumes other libraries have been defined globally.  Since the introduction of ES modules, it is a bad practice to pollute the global namespace, or to rely on global definitions from other libraries.

Even Node.js supports ES modules, so older types of modules are not necessary.  For more info, see:
