Description: Peer dependency is a type of dependency in the npm (Node Package Manager) ecosystem that refers to a package required by another package but expected to be provided by the consuming project. This means that, unlike regular dependencies that are automatically installed, peer dependencies are not automatically installed when the package that requires them is installed. Instead, the project developer must ensure that the peer dependency is present in their own project. This approach allows for greater flexibility and control over dependency versions, as the consumer can choose which version of the peer dependency to use. Peer dependencies are particularly useful in situations where version conflicts need to be avoided or when working with libraries that must interact with a specific environment. In summary, peer dependencies are a key tool in npm package management, allowing developers to have greater control over the libraries they use and how they integrate into their projects.
