A service manager for node which makes it easy to install node.js modules as native services (daemons) on Windows, Linux and OS X.
If an installed service fails or the system has been rebooted, the service will be automatically restarted.
npm install -g nsm
A package.json with at least name, description and main is required in the service directory.
Inside the service directory use
nsm to get a short usage description.
To install and start a service use:
nsm --installnsm --start
nsm requires root privileges on all platforms.
nsm --install --name=anothername --script=src/server.js --env.NODE_ENV=productionnsm --start --name=anothername
This example will show you how to install a simple hello world service which crashes after a configurable amount of time.
Following parameters can be configured in config.json:
Create a new directory named services (e.g.: in your home directory).
mkdir servicescd services
Install sample service which can be found here: nsm-sample-service
npm install nsm-sample-service
Move into installed sample service directory.
Install and start the service.
sudo nsm --installsudo nsm --start
Go to http://localhost:8000 to check whether the service runs. It should report the current uptime and fail after 45 seconds in the default configuration.
After a short amount of time it should be automatically restarted.
If you make changes to your config.json you need to restart the service.
sudo nsm --restart
Error: Cannot find module 'npm'
Add NODE_PATH (e.g.: C:\Program Files\nodejs\node_modules) to your environment variables.
