Stop node.js program from command line

Question

I have a simple TCP server that listens on a port.

var net = require(\"net\");

var server = net.createServer(function(socket) {
    socket.end(\"Hello!\\n\"         


        

Answer 1

To end the program, you should be using Ctrl + C. If you do that, it sends SIGINT, which allows the program to end gracefully, unbinding from any ports it is listening on.

Answer 2

If you are running Node.js interactively (the REPL):

Ctrl + C will take back you to > prompt then type:

process.exit()

or just use Ctrl + D.

Answer 3

Though this is a late answer, I found this from NodeJS docs:

The 'exit' event is emitted when the REPL is exited either by receiving the .exit command as input, the user pressing <ctrl>-C twice to signal SIGINT, or by pressing <ctrl>-D to signal 'end' on the input stream. The listener callback is invoked without any arguments.

So to summarize you can exit by:

1. Typing .exit in nodejs REPL.
2. Pressing <ctrl>-C twice.
3. pressing <ctrl>-D.
4. process.exit(0) meaning a natural exit from REPL. If you want to return any other status you can return a non zero number.
5. process.kill(process.pid) is the way to kill using nodejs api from within your code or from REPL.

Answer 4

I ran into an issue where I have multiple node servers running, and I want to just kill one of them and redeploy it from a script.

Note: This example is in a bash shell on Mac.

To do so I make sure to make my node call as specific as possible. For example rather than calling node server.js from the apps directory, I call node app_name_1/app/server.js

Then I can kill it using:

kill -9 $(ps aux | grep 'node\ app_name_1/app/server.js' | awk '{print $2}')

This will only kill the node process running app_name_1/app/server.js.

If you ran node app_name_2/app/server.js this node process will continue to run.

If you decide you want to kill them all you can use killall node as others have mentioned.

Answer 5

if you are using VS Code and terminal select node from the right side dropdown first and then do Ctrl + C. Then It will work

Press y when you are prompted.

Thanks

Answer 6

Resume and kill the process:

Ctrl+Z suspends it, which means it is still running as a suspended background process.

You are likely now at a terminal prompt...

1. Give the command fg to resume the process in the foreground.

2. type Ctrl+C to properly kill it.

Alternatively, you can kill it manually like this:

(NOTE: the following commands may require root, so sudo ... is your friend)

pkill -9 node

or, if you don't have pkill, this may work:

killall node

or perhaps this:

kill $(ps -e | grep node | awk '{print $1}')

sometimes the process will list its own grep, in which case you'll need:

kill $(ps -e | grep dmn | awk '{print $2}')

.
