Can pm2 run an 'npm start' script

Question

Is there a way for pm2 to run an npm start script or do you just have to run pm2 start app.js

So in development

npm start

Answer 1

It's working fine on CentOS 7

PM2 version 4.2.1

let's take two scenarios:

1. npm start //server.js

pm2 start "npm -- start" --name myMainFile

2. npm run main //main.js

pm2 start "npm -- run main" --name myMainFile

Answer 2

you need to provide app name here like myapp

pm2 start npm --name {appName} -- run {script name}

you can check it by

pm2 list

you can also add time

pm2 restart "id" --log-date-format 'DD-MM HH:mm:ss.SSS' or pm2 restart "id" --time

you can check logs by

pm2 log "id" or pm2 log "appName"

to get logs for all app

pm2 logs

Answer 3

To run PM2 with npm start method and to give it a name, run this,
pm2 start npm --name "your_app_name" -- start

To run it by passing date-format for logs,
pm2 start npm --name "your_name" --log-date-format 'DD-MM HH:mm:ss.SSS' -- start

Answer 4

If you use PM2 via node modules instead of globally, you'll need to set interpreter: 'none' in order for the above solutions to work. Related docs here.

In ecosystem.config.js:

  apps: [
    {
      name: 'myApp',
      script: 'yarn',
      args: 'start',
      interpreter: 'none',
    },
  ],

Answer 5

Don't forget the space before start

pm2 start npm --[space]start

so the correct command is:

pm2 start npm -- start

Answer 6

PM2 now supports npm start:

pm2 start npm -- start

To assign a name to the PM2 process, use the --name option:

pm2 start npm --name "app name" -- start
