Run many nodejs servers in one command

Question

I have few Nodejs servers, they are small servers and each one of them is stored in a separate folder. And all the folders are stored in one root folder. Every time i want to run the servers i have to go through each one of them and type

nodemon *name*.

This is becoming tiresome, especially that the number of servers is growing. is there any tool or a script i could use to run all the servers in one command?? Basically, how can i run all the servers in one command or a script?

You can write a shell script to run the commands you run manually. — Mike Tung, Feb 07 '19 at 13:39

With NPM. Write this in package.json :

{
  "name": "project-name",
  "version": "1.0.0",
  "scripts": {
    "start": "nodemon server1.js | nodemon server2.js | nodemon server3.js"
  }
}

Then you only need to execute npm start.

Is this Windows portable? – zero298 Feb 07 '19 at 17:01

PM2 is a great answer for this.

pm2 start app.js -i 4 (or max will take up all available cores)

You also get great benefits such as automatic restarts, log aggregation and load balancing.

ah, good idea, I use PM2 in prod, but I didn't think about this solution in a dev environment. – Jeremy Thille Feb 18 '19 at 11:32

Use pm2

If you use Linux

#!/bin/bash 

pm2 start << Path to User Server>> 
pm2 start << Path to User Server>> 

pm2 logs

You can save

pm2 save 

pm2 list 

pm2 stop
