node-hello-world

node-hello-world

This is an example Express server, which serves an API.

Express is the "fast, unopinionated, minimalist web framework for Node.js".

To run:

npm install
npm start

The app will now start on http://localhost:3000

If you hit http://localhost:3000/greeting you'll get a greeting:

$ curl localhost:3000/greeting
{"greeting":"Hello, world!"}

Put it in a container

Build a Docker image:

docker build -t node-hello-world .

Now start a container from the image:

docker run --network=host node-hello-world

You'll be able to access the API at http://localhost:3000/greeting.
