npm and npx
Both npm and npx are tools that come with Node.js, but they serve different purposes.
npm

npm Commands
- remove packages, as well as manage project dependencies.:
- npm install
: Installs a package. - npm uninstall
: Removes a package. - npm update: Updates all packages to the latest versions.
- npm list: Lists installed packages and their versions.
npx
Full Form: Node Package Executor
Purpose: npx is used to execute binaries from Node modules or packages without needing to install them globally. It's especially handy for running CLI tools that are part of your project or that you don't want to install globally.
npx Commands
- npx
: Runs a command from a package. For example, npx create-react-app my-app will run the create-react-app command without needing to install it globally.
Example Scenario

This command runs create-react-app without having it installed globally.
npx create-react-app my-appIf you wanted to install create-react-app globally for repeated use, you would use:
Bellow code uses npm to install create-react-app globally
npm install -g create-react-app
Summary
To run Node.js packages without having to install them globally, npx is very helpful. We can use it to run command-line interface (CLI) tools, run scripts, and carry out other operations.
