问题
I'm starting with Node.js world and I noticed that node process doesn't restart automatically.
Searching around I found that nodemon can do that work but I also found that PM2 is an alternative to nodemon. So should I try PM2 for development or just leave it for production and use nodemon for development (which seems very easy to setup)?
回答1:
A node process should not restart unless told to do so. You can use PM2 for development with the watch feature - similar results to nodemon. I recommend PM2 if you want to pass in a bunch of environment variables from your PM2 ecosystem.config.js file. Otherwise, I’d use nodemon as @AKX said.
回答2:
I will just add that there is pm2-dev utility http://pm2.keymetrics.io/docs/usage/pm2-development/ as well.
