Does React.lazy() require webpack?

Question

I was reading the docs on React.lazy() and it wasn't clear to me whether using that API requires me to use a module bundler that supports that syntax.

What if I am not using any bundler and just using <script type="module" src="example.mjs"></script> to provide modules, will React.lazy() still work and does it even make sense to do so?

Answer 1

Without bundler React.lazy will not work because it depends on dynamic imports.
Dynamic imports it is not a feature that browsers support for now(it is ecmascript proposal), but bundlers do.
So answer is yes. Read more about dynamic imports in webpack.
