About:
Watchexec is a command-line tool that monitors file paths for changes and executes commands in response. It provides robust filtering capabilities, including glob patterns and .gitignore support, to avoid unnecessary triggers. The tool is designed for performance and reliability, making it ideal for development workflows.
|
Key Features:
- Cross-platform file system monitoring
- Advanced filtering with glob patterns and .gitignore support
- Debouncing to prevent rapid, repeated executions
- Signal handling and process management
- Shell command execution
|
Use Cases:
- Automatically recompiling code or restarting a server during development
- Running tests or linters when source files are saved
- Triggering build scripts for documentation or assets
|
Alternatives:
-
fswatch
– fswatch is a cross-platform file change monitor, but watchexec offers more integrated command execution and filtering.
-
inotify-tools
– inotify-tools is Linux-specific and lower-level; watchexec provides a more user-friendly interface and cross-platform support.
