dependencies、devDependencies、optionalDependencies peerdependencies peerDependenciesMeta、bundleDependencies区别

dependencies: These are the packages that are required for the code to run. They are installed automatically when the package is installed.

devDependencies: These are the packages that are only required for development purposes, such as testing, building, and debugging. They are not installed by default when the package is installed, but they can be installed with a separate command.

optionalDependencies: These are packages that are not required for the code to run, but are recommended or useful in certain scenarios. They are installed automatically if available, but if they are not available, the package will still run without them.

peerDependencies: These are packages that the package relies on to be installed by the user of the package. They are not installed automatically, but the user is prompted to install them when they install the package.

peerDependenciesMeta: This is a new feature in npm 7, which allows developers to specify additional metadata for peerDependencies, such as the minimum version required.

bundleDependencies: These are packages that are included in the package when it is bundled for distribution. They are installed automatically when the package is installed, but they are not included in the package's dependencies
