- The author discusses the challenges of managing multiple Node.js projects with different version requirements on a single machine.
- Initially, NVM (Node Version Manager) was used to manage different Node/npm versions, but security concerns led to adopting Docker for isolation.
- Recent vulnerabilities in npm packages, including compromised packages and malicious ones stealing crypto keys, highlight the need for secure setups.
- The author shares their initial struggles with Docker, including issues with node_modules and package-lock.json not syncing between host and container.
- A detailed Docker setup is provided, including a Dockerfile and docker-compose.yml configuration, emphasizing volume mounts for package.json, package-lock.json, and node_modules.
- The setup includes environment variables for npm cache location to ensure logs and cache data persist and are accessible.
- Usage instructions are provided for installing packages and running the app within Docker, including commands and script examples from package.json.
- Benefits of using Docker for Node/npm projects are listed, such as environment consistency, isolation, ease of deployment, simplified onboarding, and enhanced security.
- Security caveats are mentioned, advising minimal permissions in CI/CD, multi-stage builds, and avoiding unnecessary exposure of secrets.
- The author concludes by noting the setup's effectiveness for their workflow and invites feedback on alternative Docker usage with Node.js.
