How does tree shaking work in Vue with Webpack?

How does tree shaking work in Vue with Webpack?

Tree shaking is a feature in Webpack that eliminates unused code from your final bundle. In Vue, it helps reduce the size of your application by only including the components and libraries that are actually used.

Can you explain how to set it up in a Vue project?

To set up tree shaking in a Vue project, ensure you're using ES6 module syntax. Webpack will automatically tree shake your code during the build process if you import only the components you need.

Are there any specific configurations I need to add to my Webpack config?

Generally, no specific configurations are needed for tree shaking to work, but you should ensure that the mode is set to 'production' in your Webpack config, as this enables optimizations like tree shaking.

What about third-party libraries? Do they support tree shaking?

Many modern libraries support tree shaking, especially those that are built with ES modules. However, it's always good to check the library's documentation to confirm.
