Package Registry

A package registry is a centralized repository or service that stores, manages, and distributes software packages, libraries, or dependencies for developers. It enables version control, dependency resolution, and secure distribution of code artifacts across teams and projects. Common examples include npm for JavaScript, PyPI for Python, and Docker Hub for container images.

Also known as: Package Repository, Package Manager Registry, Artifact Repository, Dependency Registry, Pkg Registry

Why learn Package Registry?

Developers should use a package registry to streamline dependency management, ensure consistent builds, and facilitate code reuse across projects. It is essential in modern software development for automating package installation, managing version conflicts, and enabling secure, auditable distribution of internal or public packages in CI/CD pipelines.
