How can I use Docker with my NPM scripts?

You can create a Dockerfile that sets up your environment and runs your NPM scripts inside a container.

Can you show me a basic Dockerfile example for a Node.js project?

Sure! Here's a simple Dockerfile:

FROM node:14
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
CMD ["npm", "start"]

This sets up a Node.js environment and installs your dependencies.

How do I build and run the Docker container?

You can build the container with docker build -t my-app . and run it using docker run -p 3000:3000 my-app.

What if I want to run tests using Docker?

You can modify the CMD in your Dockerfile to run tests instead, like this: CMD ["npm", "test"].
