Turbowatch is a file change detector and task orchestrator for Node.js that provides a more capable alternative to tools like Nodemon. It watches specified directories for file changes and executes user-defined tasks in response, featuring debouncing to batch rapid changes, retry logic for failed tasks, interruptible tasks to cancel ongoing operations, and graceful shutdown handling. The architecture uses a pluggable backend system for file watching (supporting native FSWatcher on macOS, falling back to Chokidar elsewhere), with an event processing pipeline that deduplicates and distributes changes to relevant subscribers. Key entry points include the CLI (bin/turbowatch.ts) and programmatic API (src/watch.ts). The system relies on dependencies like chokidar, zx for process spawning, micromatch for pattern matching, and roarr for structured logging.
