@parcel/watcher-wasm provides native file system watching capabilities for Node.js, compiled to WebAssembly. It offers significantly improved performance and efficiency compared to pure JavaScript watchers. Designed primarily for use by Parcel, this package allows developers to monitor file system changes with greater reliability and speed, triggering updates and rebuilds more effectively. By leveraging native libraries compiled to WASM, it brings near-native performance to cross-platform file watching solutions.
