Dynamic imports for all

Using dynamic import in legacy compiled-to-JS environments can be problematic. It's often transpiled to require by Babel, TypeScript etc. Configurations can be changed to not do this, but that can have other unintended side effects on resulting compiled code.

inclusion wraps import so that it can be used in these scenarios. It's also fine to use it for other scenarios.

API

inclusion(modulePath) => Promise => exports

Given an ESM module (someEsmModule) like the following:

export default function () { return 'hi' }
export const ABC = 123 

We can import and interact with it in a CJS environment (which is what most compile-to-JS libraries still currently do, as used in the wild), like so:

'use strict'
async function doSomething () {
  const { default: someEsmModule, ABC } = await inclusion('some-esm-module')
  console.log(someEsmModule(), ABC) // hi 123
}
