Deployment using a Node.js process manager (PM2)
Deployment using a Node.js process manager (PM2)#
PM2 is a popular and maintained process manager based in Node.js (https://pm2.keymetrics.io/).
Note
You can use the good old known supervisord as well. However, the supervisord project is stalled and in low maintenance mode for many years. PM2 is a good alternative, and as you'll see you can manage all kind of processes, not only Node.js ones, including the Plone processes.
Create a file mywebsite.com.pm2.config.js
in your repository or on your server.
Important
Make sure your PM2 config file suffix ends in config.js
, otherwise PM2 will ignore it.
