Breaking Changes

• Rollup now requires at least Node 10 to run, or a sufficiently modern browser (#​3346)

• The file structure of Rollup's ESM builds has changed:

  • The main ESM entry point is now at rollup/dist/es/rollup.js instead of rollup/dist/rollup.es.js
  • The ESM browser build is at rollup/dist/es/rollup.browser.js instead of rollup/dist/rollup.browser.es.js

  In general, the ESM builds now follow the same naming scheme as the CJS builds but are located in the rollup/dist/es subfolder instead of rollup/dist (#​3391)

• The "watch.chokidar" option no longer accepts a boolean value but only an object of parameters that is passed to the bundled Chokidar instance. Chokidar installations by the user will be ignored in favour of the bundled instance (#​3331)

• Modules that are completely tree-shaken will no longer be listed as part of any chunks in generateBundle

• The experimentalOptimizeChunks and chunkGroupingSize options have been removed

• acorn plugins can only be used if they accept a passed-in acorn instance instead of importing it themselves. See acornjs/acorn#​870 (comment) for what needs to be done to make plugins compatible that do not support this yet (#​3391)

• Emitted chunks now have the TypeScript type UInt8Array instead of Buffer. A Buffer can still be used, though (#​3395)

• The TypeScript types no longer use ESTree types for AST nodes but a very generic type that does not contain information specific to certain node types (#​3395)

• The signature of the writeBundle plugin hook has been changed to match generateBundle: The bundle object is now passed as second parameter instead of first and the first parameter is the output options (#​3361)

• The following plugin hooks have been removed:

  • ongenerate: use generateBundle instead
  • onwrite: use writeBundle instead
  • transformBundle: use renderChunk instead
  • transformChunk: use renderChunk instead

• You can no longer access this.watcher on the plugin context.

• The transform hook can no longer return dependencies.

• The treeshake.pureExternalModules option will now show a deprecation warning when used: use treeshake.moduleSideEffects: 'no-external' instead

• Using import.meta.ROLLUP_ASSET_URL_<..> and import.meta.ROLLUP_CHUNK_URL_<..> in code will now show warnings: use import.meta.ROLLUP_FILE_URL_<..> instead

• The resolveAssetUrl hook will now show a deprecation warning when used: use resolveFileUrl instead

• The following plugin context functions will show warnings when used:

  • this.emitAsset: use this.emitFile
  • this.emitChunk: use this.emitFile
  • this.getAssetFileName: use this.getFileName
  • this.getChunkFileName: use this.getFileName
  • this.isExternal: use this.resolve
  • this.resolveId: use this.resolve

• Directly adding properties to the bundle object in the generateBundle is deprecated will show a warning (removing properties is allowed, though): Use this.emitFile

• Accessing chunk.isAsset on the bundle is deprecated: Use chunk.type === 'asset' instead

• The error code for a missing name property when targeting UMD has been changed to MISSING_NAME_OPTION_FOR_IIFE_EXPORT to emphasize this is needed for the IIFE part of UMD (#​3393)

Features

• Rollup now bundles Chokidar for a better watch experience (#​3331)
• Rollup now bundles acorn again, removing its only external dependency (#​3391)
• Do not consider empty imports from side-effect-free modules for chunking and hoist side-effect imports if necessary (#​3369)
• Rollup can now be imported as an ES module in Node via import {rollup} from 'rollup'. Note that this relies on Node's experimental conditional package exports feature and is therefore itself experimental (#​3391)
• systemjs can be used as format alias for system (#​3381)

Bug Fixes

• Unknown output options now trigger a warning when using the JavaScript API (#​3352)
• Rollup will no longer introduce Node types into TypeScript projects that do not use them (#​3395)
• Generate correct sourcemaps when tree-shaking occurs in a multi-file bundle (#​3423)
