package.json |
The package manifestEach package has a manifest, which provides information about the package to the Package Manager. The manifest contains information such as the name of the package, its version, a description for users, dependencies on other packages (if any), and other details. More info See in Glossary, which defines the package dependencies and other metadata. |
README.md |
Developer package documentation. This is generally documentation to help developers who want to modify the package or push a new change on the package master source repository. |
CHANGELOG.md |
