Why Set Up a Private NPM Registry?
Public npm registries serve as a rich source of open-source packages, but there are several reasons organizations opt for a private registry:
- Control and Security: Maintain control over the packages used within your organization, ensuring compliance with security policies and minimizing the risk of using vulnerable dependencies.
- Privacy: Keep proprietary or sensitive code within the confines of your organization’s network, preventing exposure to the public.
- Performance: Reduce reliance on external networks by hosting packages locally, leading to faster installation and fewer network-related issues.
- Customization: Customizing the registry to meet your organization’s specific needs, including custom packages, access controls, and integration with existing infrastructure.
