This project contains a simple vanilla Node.js application that responds with "Hello World!" and OK 200
Either Node.js (latest LTS recommended) or Docker, depending on the chosen setup.
The application can be run in two environments.
- Node.js - on the Node.js runtime on your machine
- Docker - inside docker container
Install the dependencies.
npm install
Start the server either directly with Node or the predefined npm script.
PORT=3000 node server.js
or
npm start
NOTE: that I use port 3000 here because it is most likely not used by any other application. Feel free to change it
build the Docker image where helloworldnode could be any name.
docker build -t helloworldnode .
Start the server by running a container with build image.
docker run -p 3000:8080 helloworldnode
NOTE: that I am mapping container port 8080 to port 3000 here, because it is most likely not used by another application. You can change it at any time.
The application can be accessed at http://localhost:3000/.
