NPM Common commands in Nodejs

npm Install <name> installation Nodejs Dependency Pack

For example, NPM install Express installs the latest version of Express by default, or you can install the specified version by adding the version number later, such as NPM install [email protected]

npm Install <name>-G packages are installed in the global environment

But in the code, the direct way through require () is that there is no way to call a globally installed package. The global installation is for the command line, as if the Vmarket is installed globally, you can run the VM command directly on the command line

npm Install <name>--save to write information to Package.json

If you have a Package.json file in the project path, you can use the NPM install method directly to install all the dependent packages based on the dependencies configuration

When this code is submitted to GitHub, it is not necessary to commit the Node_modules folder.

NPM init will guide you through the creation of a Package.json file, including name, version, author information, etc.

npm Remove <name> Remove

NPM update <name> update

NPM ls lists all the packages that are currently installed

NPM root View the installation path for the current package

NPM root-g View the installation path for a global package

NPM Help helps, if you want to view the help of the install command separately, you can use the NPM helper install
