Pm2: Different config watсh for development and production

[cawa-93]

I want to set up PM2 as follows:
For development env:

watch: ['app', 'config', '.env'],

For production env

watch: false

How to implement this approach?

[cawa-93]

I tried to create two separate files with different settings for the environment. But now I'm getting an error when trying to run

pm2 startOrRestart ./config/pm2-development.js --only madpost

I'd also like to know if this is a valid approach. Currently it doesn't work like that or I may have misconfigured something.

[nicotroia]

using startOrRestart command gives me that error as well. (Cannot read property 'deploy' of undefined). Using start/restart separately makes it work as normal

[gabriel-garcia]

I'm also having this issue. Is there any way to make startOrRestart work without having to resort to start/restart ?

Edit: Nevermind, adding a configuration file fixed the issue. I was running a command directly without config.
