How to setup supervisor 3.3.1 with node.js npm scripts

  • 772

I'm running version 3.3.1.

Apart of my /etc/supervisor/supervisord.conf file:

[program:node]
directory=/srv/www
command=npm run demo
autostart=true
autorestart=true

Apart of my package.json file under scripts:

"demo": "npm run prod",
"prod": "NODE_ENV=production NODE_PATH=\"$(pwd)\" node src/index.js"

I attempt to shutdown the node program via supervisorctl, however it persists.

I'm wondering how do I setup supervisor with a node npm script properly. The internet guides have shown nothing but what I've done above. I have no control over stopping/starting it.

supervisord

  1. I solved this by creating a script in my package.json like this:

    ...
"scripts": {
    "start-continuous": "supervisor server/server.js",
},
...

    This will work if you have supervisor installed in your global scope.

    npm install supervisor -g

    Now all I do is: npm run start-continuous

    I hope this helps.
