Understanding when and why to use npm peerDependencies

In this article I hope to clarify what npm Peer Dependencies are and especially when you should use them. Peer Dependencies are listed in the package.json file in the peerDependencies object.

To get the most out of this article you should have at least an introductory understanding of npm.

In this article:

1. We will compare exactly how Dependencies work versus Peer Dependencies.
2. We will look at some examples of both Dependencies and Peer Dependencies.
3. Then, we will examine how npm handles version conflicts.
4. Finally, having the fundamentals solidly in our grasp, we will lay out an approach to deciding when Peer Dependencies are appropriate.
