A node package has two types of dependencies, one is dependencies and the other is devdependencies. The former depends on the items that are required to run the package normally, the latter is the dependencies required during development, such as some packages for unit testing.

If you download the package and run it in the package root directory

npm install 


By default, two types of dependencies are installed. If you only use this package and do not need to perform some changes, you can use

npm install --production


Only dependencies are installed, but not devdependencies.

Run the following command to install

npm install packagename


Only dependencies will be installed. If you want to install devdependencies, enter

npm install packagename --dev
