Node and docker

I don’t tend to install node on my laptop as I don’t want to clutter my machine with a lot of different software. I like to try stuff out save it to github and forget about it for a few months. Docker lets me do this.

for example to run a quick node script

docker run -p8080:8080 -v "$PWD":/app node:9-alpine node app/console.js

console.js

console.log("Hello World!");

Another example – running a webserver.

docker run -p8080:8080 -v "$PWD":/app node:9-alpine node app/webserver.js

webserver.js

http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/html'});
res.end('Hello World!');
}).listen(8080);
