Understanding these fields can help developers better understand and control the behavior of the project. package.json for most front-end developers, knowing dependencies and devDependencies is enough. However, for library developers or developers with more advanced needs, it is necessary to understand the other fields of package.json. the fields introduced in this article are divided into official fields and unofficial fields.
