import { Router, DefaultDependencies } from './types/router';
/**
 * Creates a deep clone of an existing router instance with optional new dependencies.
 *
 * The cloned router will have:
 * - Same route tree structure
 * - Same configuration options
 * - Same middleware and plugins
 * - Same lifecycle handlers (canActivate/canDeactivate)
 * - Same configuration object
 * - Optionally different dependencies
 *
 * This is useful for creating router instances with different dependency contexts
 * while maintaining the same routing configuration.
 *
 * @template Dependencies - Type of dependencies to inject into the cloned router
 * @param router - The router instance to clone
 * @param dependencies - Optional new dependencies for the cloned router
 * @returns A new router instance that is a clone of the original
 *
 * @example
 * ```typescript
 * const originalRouter = createRouter(routes, options, { api: apiV1 })
 *
 * // Clone with different dependencies
 * const clonedRouter = cloneRouter(originalRouter, { api: apiV2 })
 *
 * // Clone with same dependencies
 * const identicalRouter = cloneRouter(originalRouter)
 * ```
