Different ways to kill or stop node process in Windows and Linux

When you start running an API nodeJS server, a frontend web server, and a test case, a NodeJS process is created. You may also use the command line or the Visual Studio code terminal to run all of these.

Angular, React, and Vuejs are examples of front-end frameworks.

Sometimes, You may need to stop a single process or all processes for debugging. Another way, You closed Visual Studio code without terminating the node process running in the terminal. For instance, suppose you’re using the ng command to execute an Angular application.

ng serve

It stars the server and listens to 4100 ports.

Each service or operation in an operating system like Windows, Linux, or Unix creates a process, and each node does the same.

Process Id is assigned to each process.

You must first kill the process to stop it.

You will learn how to kill or stop node server - single node process - all node instances in this tutorial.

How to kill node process in Linux

In this example,

You can get a process id with a port number or named process

One way, get process ID for a given 8080 port using the below command.

netstat -lpn |grep :8080

Another way, get process ID for a given node process name using the below command.

ps aux | grep node

This gives an output something like this and it contains Process Id

tcp    0     0 0.0.0.0:80     0.0.0.0:*     LISTEN      8795/node    

you kill nodejs process by process id.

In this case, ProcessId is 8795

kill the process using -f forcefully option

kill -9 8795

This kills or stop a single specific node process.

How to stop all instances of node.js server in Unix

It is simple to kill all node processes using the below command

killall -9 node

How to stop single or instances of node.js server in windows

nodejs process is running an executable file node.exe in windows.

One way is stop single node process in Windows Find all process ids for a given port listening.

netstat -ano | find "LISTENING" | find "4100"

It lists out all process ids for given port 4100

  TCP    0.0.0.0:4100           0.0.0.0:0              LISTENING       17846

you can kill the process using the taskkill command

taskkill /pid 17846

use the /f option for killing a single process forcefully.

taskkill /f /pid 17846

The second way, kill all node process in Windows

You need to kill this file using the below command taskkill is a command to kill in process in Windows

taskkill /im node.exe

use /f option to kill it forcefully

taskkill /im /f node.exe

This stops and kill all node process in windows.

Conclusion

Above all, kill and killall commands are available in Mac and Unix Operating systems. So It works on all ubuntu and UNIX flavors OS.

To Sum up, You learned how to stop and stop all processes in Windows and Unix.
