* rendered as namespace imports.
*
* You can also supply an array of ids to be treated as ES modules, or a

/**
* Controls what is returned when requiring an ES module from a CommonJS file.
* When using the `esmExternals` option, this will also apply to external
* modules. By default, this plugin will render those imports as namespace
* imports i.e.
*
* ```js
* // input
* const foo = require('foo');
*
* // output
* import * as foo from 'foo';
* ```
*
* However, there are some situations where this may not be desired.
* For these situations, you can change Rollup's behaviour either globally or
* per module. To change it globally, set the `requireReturnsDefault` option
* to one of the following values:
*
* - `false`: This is the default, requiring an ES module returns its
* namespace. This is the only option that will also add a marker
* `__esModule: true` to the namespace to support interop patterns in
* CommonJS modules that are transpiled ES modules.
* - `"namespace"`: Like `false`, requiring an ES module returns its
* namespace, but the plugin does not add the `__esModule` marker and thus
* creates more efficient code. For external dependencies when using
* `esmExternals: true`, no additional interop code is generated.
* - `"auto"`: This is complementary to how `output.exports: "auto"` works in
* Rollup: If a module has a default export and no named exports, requiring
* that module returns the default export. In all other cases, the namespace
* is returned. For external dependencies when using `esmExternals: true`, a
* corresponding interop helper is added.
* - `"preferred"`: If a module has a default export, requiring that module
* always returns the default export, no matter whether additional named
* exports exist. This is similar to how previous versions of this plugin
* worked. Again for external dependencies when using `esmExternals: true`,
* an interop helper is added.
* - `true`: This will always try to return the default export on require
* without checking if it actually exists. This can throw at build time if
* there is no default export. This is how external dependencies are handled
* when `esmExternals` is not used. The advantage over the other options is
* that, like `false`, this does not add an interop helper for external
* dependencies, keeping the code lean.
*
* To change this for individual modules, you can supply a function for
* `requireReturnsDefault` instead. This function will then be called once for
* each required ES module or external dependency with the corresponding id
* and allows you to return different values for different modules.
* @default false
