Dynamic, Conditional Imports

With ES Modules, you can natively import other JavaScript. Like confetti, duh:

import confetti from 'https://cdn.skypack.dev/canvas-confetti';

That import statement is just gonna run. There is a pattern to do it conditionally though. It’s like this:

(async () => { if (condition) { // await import("stuff.js"); // Like confetti! Which you have to import this special way because the web const { default: confetti } = await import( "https://cdn.skypack.dev/[email protected]" ); confetti(); }

Why? Any sort of condition, I suppose. You could check the URL and only load certain things on certain pages. You could only be loading certain web components in certain conditions. I dunno. I’m sure you can think of a million things.

Responsible, conditional loading is another idea. Here’s only loading a module if saveData isn’t on:
