Install Webpack-CLI in Node.js - Quick Guide

Webpack-CLI is a powerful tool for managing Webpack configurations. It helps automate tasks like bundling and optimizing assets. This guide will walk you through installing it in Node.js.

Prerequisites

Before installing webpack-cli, ensure you have Node.js and npm installed. You can check by running:

node -v
npm -v

If not installed, download Node.js from the official website. For more details, check our guide on Install Webpack in Node.js.

Install Webpack-CLI Globally

To use webpack-cli across projects, install it globally. Run:

npm install -g webpack-cli

This installs the latest version. Verify the installation with:

webpack-cli --version

Install Webpack-CLI Locally

For project-specific use, install it locally. Navigate to your project folder and run:

npm install --save-dev webpack-cli

This adds webpack-cli to your devDependencies in package.json.

Verify the Installation

After installation, verify it works. Create a simple configuration file named webpack.config.js:

module.exports = {
  entry: './src/index.js',
  output: {
    filename: 'bundle.js',
  },
};

Run Webpack using:

npx webpack

This bundles your files. For more complex setups, refer to our Install Next.js in Node.js guide.

Troubleshooting Common Issues

If you encounter errors, ensure Node.js and npm are up-to-date. Update them using:

npm install -g npm@latest

For permission issues, use sudo (Mac/Linux) or run the terminal as admin (Windows).
