What is a npm command?

npm has inbuilt actions that do something. Each action has an identifier using which it can be executed.The identifier is called a command.

An example of npm command is:

• list - a command that displys all installed modules
• install - a command that installs all modules mentioned in a file package.json in a property dependencies and devDependencies
• update - a command that updates all modules that have more recent version than the one youhave installed before
• outdated - a command that displays a list of outdated modules that your package is using

A command is executed from the command-line by typing:

npm <yourcommand>

If you wanted to run the commands above, you would run

npm list

npm install
