webpack-bundle-analyzer gives us useful information about what is in a bundle.
Often, I find myself wonder why a module is bundled.
Other tools are web based application which doesn't do well when stats file is large (300MB+).
That's why I decided to solve this problem.
I hope you find it useful.
npm install -g why-bundle
Usage: why-bundle [options]
Options:
-V, --version output the version number
-s, --stats <path_to_stats_file> Specify stats file to read from
-c, --chunk <chunk_name> Name of the chunk
-m, --module <module_name> Name of module to see why it is bundled (Support regular expression)
-h, --help output usage information
To find why module user/selectors.js is bundled in main chunk,
$ why-bundle -s ~/Desktop/stats.json -c main -m 'user/selectors.js'
