rollup-plugin-visualizer/dist/plugin/bundler-types.js

Visualize and analyze your bundle to quickly see which modules are taking up space.

// Minimal structural stand-ins for the bundler types this plugin touches.
//
// The plugin supports rollup, rolldown and vite. Importing types from any one of
// them would force that bundler to be installed just to typecheck: vite 8 depends
// on rolldown and no longer ships rollup at all, so an `import ... from "rollup"`
// in the published .d.ts resolves to nothing for most consumers (silently `any`
// under skipLibCheck, a hard TS2307 without it).
//
// These interfaces intentionally describe only what the plugin reads, which makes
// them structural *supertypes* of the real rollup/rolldown/vite types. That is
// what makes a single definition satisfy all of them, across bundler versions.
//
// IMPORTANT: never make a member narrower or more specific than the real thing.
// Widening a field (e.g. `format?: string` where rollup has a `ModuleFormat`
// union) breaks assignability just as surely as adding a required member does.
// test/types/assignability.ts asserts this against every supported bundler.
