Running the Server

With NodeJS installed, you can started the server by running,

node app.js


npm run start


This simple server can be easily extended. After cloning this repository you can start developing locally.

Locally (without Docker)

  1. Install Nodemon, Nodemon will watch for file changes and restart the NodeJS process. This allows for faster development and testing.
npm install -g nodemon
  1. With Nodemon installed, start the server using Nodemon
nodemon app.js


npm run start:dev

Using Docker

I prefer to use Docker for local development wherever possible. This allows me to have a consistent development environment.

Start Docker Container

With Docker installed, we can start a container using the latest NodeJS Docker image.

docker run -it --rm -p 5000:5000 -v $(pwd):/api -w="/api" node bash

Start the application in development mode using Nodemon inside your Docker Container

npm run start:dev

To stop your running NodeJS API server

ctrl + c

To quit your Docker Container development environment, in your terminal:


This will cleanup any running containers, (note: the Docker image will still exist on your machine)

You can’t perform that action at this time.
