PM2

PM2 or Node Process Manager 2 is a framework for managing long-running processes. We use it to manage the Ving web and jobs servers in production.

Setup

Install

Install PM2 globally on your server like so:

npm i -g pm2

Make a Process File

There is a file called process.json in the root of your project. Copy that file to match the name of whatever processes you need it to run for the specific environment you're targeting. For example, it could be prod.json or qa-process.json. It's up to you.

Edit the Process File

The process file has rules for what processes should be run, and how they should be managed. process.json has sane defaults, but you can change them to your liking.

By default it will run 1 nuxt process per CPU core of your server, plus 2 job workers. Click here for more information on how to configure PM2.

Using PM2

Note: To use PM2 you need to be in the root folder of your project.

pm2 start process.json

Stop the Processes
