Summary
docs/builtin-plugins/bundle-analyzer.md, documenting the experimentalbundleAnalyzerPluginexported fromrolldown/experimental.fileNameandformatoptions, the JSON output schema, and the LLM-friendly markdown report (sections, optimization-suggestion severity levels, and an example of piping the report into a coding agent) introduced in feat: add LLM-friendly markdown output format to bundle analyzer plugin #8242.docs/.vitepress/config.ts.Context
The bundle analyzer plugin already shipped with an example in
examples/bundle-analyzer-demo, but had no entry underdocs/builtin-plugins/. With the markdown output format added in #8242 and shipped inv1.0.0-rc.7, the plugin now has enough surface area to deserve its own documentation page alongsidebuiltin:replaceandbuiltin:esm-external-require.The new page follows the same structure as the existing built-in plugin docs:
:::tip EXPERIMENTALcallout noting the import path.## Usagewith a minimal config example.## Optionslisting each option with type, default, and example.## JSON Formatshowing the default output schema.## Markdown Formatdescribing each section of the markdown report, the[HIGH]/[MEDIUM]/[LOW]severity levels in optimization suggestions, and how to pipe the report into an LLM.examples/bundle-analyzer-demoexample.
