How can I use Docker for managing dependencies in my project?

You can use Docker to create isolated environments for your applications, ensuring that all dependencies are included in the container.

What are the benefits of using Docker for this purpose?

The benefits include consistency across environments, easier collaboration, and simplified deployment processes.

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

Sure! Here's a simple Dockerfile:

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

How do I build and run the Docker container?

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