How to stop app that node.js express 'npm start'

Question

You build node.js app with express v4.x then start your app by npm start. My question is how to stop the app? Is there npm stop?

Answer 1

You can use pm2

after installation just type in terminal

pm2 start app.js and then

pm2 stop 0 to stop your server

Answer 2

Check with netstat -nptl all processes

Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN      1736/mongod     
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      1594/sshd       
tcp6       0      0 :::3977                 :::*                    LISTEN      6231/nodejs     
tcp6       0      0 :::22                   :::*                    LISTEN      1594/sshd       
tcp6       0      0 :::3200                 :::*                    LISTEN      5535/nodejs 

And it simply kills the process by the PID reference.... In my case I want to stop the 6231/nodejs so I execute the following command:

kill -9 6231

Answer 3

If is very simple, just kill the process..

localmacpro$ ps
  PID TTY           TIME CMD
 5014 ttys000    0:00.05 -bash
 6906 ttys000    0:00.29 npm   
 6907 ttys000    0:06.39 node /Users/roger_macpro/my-project/node_modules/.bin/webpack-dev-server --inline --progress --config build/webpack.dev.conf.js
 6706 ttys001    0:00.05 -bash
 7157 ttys002    0:00.29 -bash

localmacpro$ kill -9 6907 6906

All (3) solotion is :

1- ctlr + C

2- in json file wreite a script that stop

"scripts": { "stop": "killall -SIGINT this-name-can-be-as-long-as-it-needs-to-be" },

*than in command write // npm stop //

3- Restart the pc

Answer 6

Yes, npm provides for a stop script too:

npm help npm-scripts

prestop, stop, poststop: Run by the npm stop command.

Set one of the above in your package.json, and then use npm stop

npm help npm-stop

You can make this really simple if you set in app.js,

process.title = myApp;

And, then in scripts.json,

"scripts": {
    "start": "app.js"
    , "stop": "pkill --signal SIGINT myApp"
}

That said, if this was me, I'd be using pm2 or something the automatically handled this on the basis of a git push.
