How to install pnpx

pnpx is actually a command provided by the npm package manager, used to execute executable files from npm packages. pnpx is designed to help developers run packages on a one-off basis without global installation. From npm@5.2.0 onwards, npx is automatically installed with npm, so it is usually unnecessary to install pnpx separately.

Installation Steps:

1. Install Node.js and npm:
   First, ensure that Node.js and npm are installed on your system. Since npx is bundled with npm, confirm Node.js installation first. You can download and install Node.js from the official website nodejs.org, which includes npm automatically.

2. Verify Installation:
   After installation, verify that Node.js and npm are correctly installed by running the following commands in the terminal:

bash
node -v
npm -v

1. Use npx (i.e., pnpx):
   Once npm is confirmed installed, you can directly use the npx command to run any npm package. For example, to run the create-react-app package, use:

bash
npx create-react-app my-app

This command will temporarily download and run create-react-app, creating a new project named my-app.

Example:

Suppose you need to use the TypeScript compiler tsc to compile TypeScript files in a project without globally installing TypeScript. You can use the following command:

bash
npx tsc myfile.ts

This will temporarily install the TypeScript package (if not cached) and then run the tsc command to compile myfile.ts.

Summary:

Overall, pnpx (which is npx) is a very useful tool in npm, as it avoids the need for global package installation and allows quick execution of packages when needed, making it ideal for one-off tasks or switching between multiple package versions.
