Dynamic, Conditional Imports

ES Modules allow native JavaScript imports. For example, importing a confetti library:

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

This import executes immediately. However, conditional loading is possible using this pattern:

(async () => {
  if (condition) {
    // await import("stuff.js");

    // Conditional import of confetti (requires this specific syntax due to its nature)
    const { default: confetti } = await import(
      "https://cdn.skypack.dev/canvas-confetti@latest"
    );
    confetti();
  }
})();

The conditional approach is useful for various scenarios. For instance, loading modules based on the URL, or conditionally rendering web components. The possibilities are numerous.

Another key benefit is responsible, conditional loading. Consider this example, where a module only loads if saveData is false:

// ... (rest of the code)
