Dynamically inspects Spotify's webpack module cache to build a mapping of modules despite obfuscation, enabling stable access to internal APIs. This pattern is reusable for any webpack-based application to extract and expose functions/components without relying on brittle class names or hardcoded paths.

Loads extensions and custom apps from manifest.json files, manages their lifecycle, and facilitates communication via a centralized event bus. Demonstrates a reusable plugin architecture with declarative configuration, loose coupling, and runtime isolation that can be adapted to any host application.

Implements a recursive and non-recursive file watcher with debouncing to efficiently monitor file changes while minimizing event noise. Self-contained, dependency-light, and easily integrable into any Go project requiring filesystem monitoring with configurable callbacks and error handling.

Provides a robust backup and restore mechanism for application directories, featuring versioned backups, file extension filtering (.spa files), and safe restoration. This pattern is reusable for any tool that modifies files in a target application's directory and requires a reliable safety net with rollback capabilities.
