Reflex is a small Go CLI tool that watches a directory and reruns a command when matching files change. It supports regex/glob file matching, sequential or parallel execution, and restarting long-running services on change.
Use cases
- rerun tests whenever source files change
- automatically rebuild and restart a server when code changes
- run a linter on files as they are edited
- trigger make when any .c file changes
- reload an application during development on save
When to choose
- you want a simple, fast file-watcher CLI on Linux or macOS
- you need to restart a long-running dev server when code changes
- you prefer regex or glob-based file matching from the command line
When to avoid
- you need Windows support (only tested on Linux and macOS)
- you need a GUI or IDE-integrated file watcher
- you need complex multi-step build pipelines better handled by a task runner
