webpack-bundle-size-analyzer | A tool for finding out what contributes to the size | Plugin library

webpack-bundle-size-analyzer is a TypeScript library typically used in Plugin, Webpack applications. webpack-bundle-size-analyzer has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

If you minify/compress your code using the [approach recommended in the Webpack documentation] which is to use the UglifyJS plugin, be aware that this tool will report the sizes of modules before they are minified. This is because the statistics generated by webpack --json do not take account of plugins that operate on the bundle as a whole. Knowing the sizes of dependencies before they are minified can still be useful to get an idea of how much different dependencies are responsible for size of your minified bundle, but be aware that it can be misleading. This is because some libraries compress better than others. If instead you minify modules in your bundle individually using a loader (eg. [the UglifyJS loader] the stats output by webpack --json will show minified sizes. If you want to get a better idea of the sizes of different dependencies after they are minified, you can temporarily remove the UglifyJS plugin and replace it with [the UglifyJS loader] instead before running webpack --json | webpack-bundle-size-analyzer. The reason that using a plugin, rather than a loader, is the recommended approach in Webpack is that compression is better if applied to the whole bundle rather than to individual source files one at a time.
