vue-cli-plugin-webpack-bundle-analyzer v4.0.0
vue-cli-plugin-webpack-bundle-analyzer
vue-cli plugin to visualize size of webpack output files
Uses webpack-bundle-analyzer to create an interactive treemap visualization of the contents of all your bundles.

Configuration
Add a webpackBundleAnalyzer object to your pluginOptions in vue.config.js:
module.exports = {
pluginOptions: {
webpackBundleAnalyzer: {
openAnalyzer: false
}
}
};You can use any of these settings.
Production
When building your Vue project for production, the analyzerMode will be set to static. By default, the generated web page will be opened in your browser. This can be changed by setting openAnalyzer to false as shown above.
Modern Mode
When using the --modern flag to build your app, this plugin will create 2 different reports: one for your legacy build and one for your modern build. Your report filename will be prefixed with legacy- and modern- respectively.
Known Caveats
In development, you'll only be able to use the stat size due to webpack-bundle-analyzer requiring physical files to calculate parsed and gzipped sizes.
