What is Webpack configuration and how do I set it up?

Webpack configuration is a way to customize how Webpack bundles your JavaScript applications. You set it up using a configuration file, typically named webpack.config.js, where you define entry points, output settings, loaders, and plugins.

Can you explain what loaders and plugins are?

Loaders are transformations that are applied to the files before they are bundled. For example, Babel is a loader that transpiles modern JavaScript into a version compatible with older browsers. Plugins, on the other hand, are used to perform a wider range of tasks like optimizing the output or managing the build process.

How do I install Webpack and its dependencies?

You can install Webpack and its CLI by running npm install --save-dev webpack webpack-cli in your project directory. Make sure you also install any loaders or plugins you plan to use.

What are some common mistakes to avoid in Webpack configuration?

Common mistakes include not specifying the correct entry point, forgetting to include necessary loaders, and misconfiguring the output path. Always double-check your configuration file for typos and ensure all dependencies are installed.
