Node.js TCP client and server example
View nodejs-tcp-example.js
In the node.js intro tutorial (, they show a basic tcp
server, but for some reason omit a client connecting to it. I added an
example at the bottom.
Save the following server in example.js:
var net = require('net');
DOCKER_PIDS=$(docker ps -a -q)
if [ -n "$DOCKER_PIDS" ]; then
docker stop $DOCKER_PIDS && docker rm $DOCKER_PIDS
You can’t perform that action at this time.
