What are webpack-visualizer-plugin's main functionalities?

Generate Bundle Visualization

This feature allows you to generate an HTML file that visualizes the size of your webpack output files. By including the Visualizer plugin in your webpack configuration, you can produce a statistics.html file that provides a treemap visualization of your bundle.

const Visualizer = require('webpack-visualizer-plugin');

module.exports = {
  plugins: [
    new Visualizer({
      filename: './statistics.html'
    })
  ]
};

Other packages similar to webpack-visualizer-plugin

webpack-bundle-analyzer

webpack-bundle-analyzer is a similar tool that provides a visual representation of your webpack bundles. It offers an interactive zoomable treemap visualization of the contents of your bundle, similar to webpack-visualizer-plugin. However, webpack-bundle-analyzer provides more detailed insights and options, such as the ability to view the bundle content in a sunburst or network graph format, and it can be run as a standalone server.

source-map-explorer

source-map-explorer analyzes JavaScript bundles using source maps to determine which file each byte in your minified code came from. It provides a visualization similar to webpack-visualizer-plugin but focuses more on the source map data to help identify large dependencies and optimize bundle size. Unlike webpack-visualizer-plugin, it is not limited to webpack and can be used with any JavaScript bundle that has a source map.
