How to use pm2 start npm in a specific directory?

Is there a CLI tag for running pm2 start npm -- start in a specific directory? I looked around but could not find an answer.

On the other hand, when I run pm2 without npm, I can specify which directory I want to run pm2 in. For example:

pm2 start /opt/www/myapp/index.js

Is there any way to add a path tag to the pm2 start npm -- start command?

Solution

  • You can use something like this:

    cd /directory/of/my/app ; pm2 start npm -- start

    You can also write an ecosystem file to parameter you app:

    {
    "apps": [
        {
            "name": "my-app",
            "cwd": "/path/to/app",
            "script": "npm",
            "args": "start"
        }
    ]
}

    To generate an empty ecosystem file:

    pm2 init simple

    this will generate a file named ecosystem.config.js that you can rename.

    Then to start application:

    pm2 start ecosystem.config.js
