Sorry, something went wrong.

Uh oh!

There was an error while loading. Please reload this page.

Follows @giltayar's proposed API:

> `register` can pass any data it wants to the loader, which will be
passed to the exported `initialize` function of the loader.
Additionally, if the user of `register` wants to communicate with the
loader, it can just create a `MessageChannel` and pass the port to the
loader as data.

The `register` API is now:

```ts
interface Options {
  parentUrl?: string;
  data?: any;
  transferList?: any[];
}

function register(loader: string, parentUrl?: string): any;
function register(loader: string, options?: Options): any;
```

This API is backwards compatible with the old one (new arguments are
optional and at the end) and allows for passing data into the new
`initialize` hook. If this hook returns data it is passed back to
`register`:

```ts
function initialize(data: any): Promise<any>;
```

**NOTE**: Currently there is no mechanism for a loader to exchange
ownership of something back to the caller.

**What's the problem this PR addresses?**

nodejs/node#48842 changed it so that our fs
patch is loaded after the internal translators so ESM importing named
CJS exports in loaders doesn't work.

Fixes #5951

**How did you fix it?**

Updated our ESM loader patching to target the `fs` bindings used
internally.
