supervisor
A supervisor script for Node.js that restarts programs when they crash or when JavaScript files change.
What is supervisor?
node-supervisor is a command-line tool for Node.js that supervises and automatically restarts your application when it crashes or when source code files change. It solves the problem of manually restarting Node.js servers during development and ensures applications remain running in production despite unexpected failures.
Node.js developers who need a simple, reliable way to keep their applications running continuously, especially during development with frequent code changes or in production environments where uptime is critical.
Developers choose node-supervisor for its minimal setup, no required code changes, and flexibility in monitoring files and managing restarts, making it a lightweight alternative to more complex process managers.
Overview
node-supervisor is a lightweight process supervisor for Node.js applications. It monitors your program and automatically restarts it if it crashes, and can also restart it when changes to JavaScript files are detected, enabling hot-code reloading behavior without requiring a complex module system overhaul.
Key Features
- Automatic Restart on Crash — Restarts the supervised program if it exits unexpectedly, ensuring continuous operation.
- File Change Detection — Watches specified directories and files for changes, triggering restarts to apply code updates.
- Configurable Watch/Ignore — Allows customizing which folders and file extensions to monitor or ignore.
- Flexible Execution — Supports running programs with different executables (e.g., Node, CoffeeScript) and debugging flags.
- Interactive Control — Provides commands like
rsto manually restart the process without file changes.
Philosophy
node-supervisor focuses on simplicity and reliability, offering a straightforward way to manage Node.js processes without introducing complex dependencies or requiring changes to your application's architecture.
