javascript - node_modules is extremely large, and many dependencies that are not included in package.json are also installed.

Question

I first wrote the dependencies of package.json and then ran cnpm install
After running, node_modules is very large, and many unwritten dependencies are also loaded. Is there any way to press package? Does .json need to be loaded?

Answer 1

The dependencies in

package.json also depend on other packages. Of course, they all need to be installed, otherwise your dependencies will not be used

Answer 2

The package you depend on in package.json also has its own dependencies.

Your package.json:

"a":"^1.0.1"

a’s package.json:

"b":"^2.1.1"

b is not in your package.json, but it must be downloaded, otherwise a will not work properly.

b probably also depends on other packages.
