How to automatically reload Node.js project when using pm2

Question

I am currently programming Node.js with Express.js, and every time I change a line of code in the file router or app, I need to type the command:

pm2 reload id_         


        

Answer 1

You need to start your pm2 project with the --watch option:

pm2 start  --watch

Where refers to:

• script the path to the script you want to let pm2 handle
• name the name of the configuration in the "ecosystem" file
• id refers to an already running application using pm2, which can be obtained using pm2 list (note that this would actually require a restart instead of start, so it's probably the least desirable of the options)

You could also specify which files/directories to ignore:

pm2 start
