What is a difference between npm command and npm script?
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- outdated - a command that displays a list of outdated modules that your package is using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:
If you wanted to run the commands above, you would run
A npm script is a set of user-defined command-line commands that can be executed using a shortcut that is called an alias.
Imagine you want to do a backup of your project directory from time to time.
How would you do it?
You could always execute a command-line command similar to "copy c:\yourproject v:\backup". But typing this repeatedly would take too much time.
To become more efficient you could create a npm script with alias called my-backup and value "copy c:\yourproject v:\backup". After you define the script, you can the execute it by running the following npm command:
npm run my-backup
