CLI

This plugin provides cli util rollup-plugin-visualizer. Add --help to check actual options. It can be used like:

rollup-plugin-visualizer [OPTIONS] stat1.json stat2.json ../stat3.json

This can be usefull in case you have different config files in the same project and you want to display all of them in the same chart.

Build plugin

For development if you need to build plugin, just exec:

yarn run build

Disclaimer about generated files

Generated html files do not and never will contain your source code (contents of files). They can contain only js/html/css code required to build chart (plugin code) and statistical information about your source code.

This statistical information can contain:

• size of files included in bundle
• size of files included in source map
• file's path
• files hierarchy (fs tree for your files)

Upgrades

See CHANGELOG.md.

Acknowledgements

Initially this plugin was based on webpack-visualizer, but in the end used only styles and layout. Thanks to the tons of people around internet for great examples of d3 usage. Also i would like to thank you Mike Bostock for awesome D3, and tons of examples.
