comparison between npm and npx

You can also check other posts on npm command deprecate option is deprecated In Nodejs, We have two commands to manage and run libraries

  • npm: Node Package Manager
  • npx: Node package executable runner

The above two come with default nodejs installation.

What is npm?

npm is an easy command-line tool to manage(install, uninstall) node javascript packages in Nodejs.

It is not easy to run and execute the installed packages with this.

What is npx?

npx is the command-line tool to run the packages locally without the installation of packages. It is very helpful without the installation of the package, directly run package runner.

Difference between npm and npx

For example, We need to create a brand new react application. For this, we have to use create-react-app cli.

Let’s do create an application with npm.

First, install the create-react-app using the npm command.

We can install locally(without -g) or globally(-g option)

npm install create-react-app -g

It installs create-react-app from the remote repo into the local developer machine. Globally installation process

  • use -g option globally
  • It creates a node_modules folder t global npm directory - /usr/local/ folder in Linux and %AppData%/npm in windows.
  • Also, Creates links for the bin folder of on global npm directory.

Local installation process

  • use without -g option for locally
  • It creates a node_modules folder at the application directory
  • Also, Creates links for the bin folder of on application/node_modules/.bin folder.
  • This path is available and installed packages command are accessible from the application folder

Once, the create-react-app is installed, It creates a link and the create-react-app command works globally.

Run the below command to create a react application

create-react-app app1

It creates a scaffolding react application app1with all required files and scripts and also installs dependencies.

Let’s create a react application with npx.

npx create-react-app my-app

With a single command, It does the following things

  • It installs create-react-app from the npm repository
  • Copy the package executable to a local path
  • Run the command directly with all required parameters

Both approaches(npm, npx) are used to create a react application using create-react-app.

create-react-app is a one-time process to create a react application, It is not required to install globally, So npx avoids downloading locally for command-line execution.

Hence, It is always a good idea to choose npx over the npm tool.
