ResolveHook
typealias ResolveHook = (specifier: String, context: ResolveHookContext, nextResolve: (specifier: String, context: ResolveHookContext?) -> <Error class: unknown class><ResolveFnOutput>) -> <Error class: unknown class><ResolveFnOutput>(source)
The resolve hook chain is responsible for telling Node.js where to find and how to cache a given import statement or expression, or require call. It can optionally return a format (such as 'module') as a hint to the load hook. If a format is specified, the load hook is ultimately responsible for providing the final format value (and it is free to ignore the hint provided by resolve); if resolve provides a format, a custom load hook is required even if only to pass the value to the Node.js default load hook.
