package.json related expansion:

Each Under the root directory of the project, there is generally a package.json file that defines the various modules required by the project, as well as the project configuration information (such as name, version, license and other metadata). The npm install command automatically downloads the required modules based on this configuration file, which is to configure the running and development environment required for the project.

The following is the simplest package.json file, which only defines two metadata: project name and project version.

{ "name" : "xxx", version" : "0.0.0", }

The above code illustrates that the package.json file contains a JSON object, and each member of the object is a setting of the current project. For example, name is the project name, and version is the version (following the format of "major version.minor version.minor version").
