How do you do both?

Usually you setup a transpiler to target both. For example, my packages are bundled with rollup towards both cjs & esm:

It's very easy to re-export ESM (import) as CJS (require) and vice-versa. The main issue is that ESM by default

For example to use `require` inside ESModules you would do:

```mjs import { createRequire } from 'module'; const require = createRequire(import.meta.url); require('./whatever-in-cjs'); ```

There is a reason this isn't "by default" though since ESM doesn't "silently" interop with CJS to not make writing universal code harder.
