/**
|
|
* Creates new custom importers that use the given `resourcePath` if libsass calls the custom importer with `prev`
|
|
* being 'stdin'.
|
|
*
|
|
* Why do we need this? We have to use the `data` option of node-sass in order to compile our sass because
|
|
* the `resourcePath` might not be an actual file on disk. When using the `data` option, libsass uses the string
|
|
* 'stdin' instead of a filename.
|
|
*
|
|
* We have to fix this behavior in order to provide a consistent experience to the webpack user.

* @param {function|Array<function>} importer
|
|
* @param {string} resourcePath
|
|
* @returns {Array<function>}
