v1.0.0

2018-12-28

• Several (mostly deprecated) options have been removed or renamed (#2293, #2409):
  • banner -> output.banner
  • dest -> output.file
  • entry -> input
  • experimentalCodeSplitting -> now always active
  • experimentalDynamicImport -> now always active
  • experimentalPreserveModules -> preserveModules
  • exports -> output.exports
  • extend -> output.extend
  • footer -> output.footer
  • format -> output.format
  • freeze -> output.freeze
  • globals -> output.globals
  • indent -> output.indent
  • interop -> output.interop
  • intro -> output.intro
  • load -> use plugin API
  • moduleName -> output.name
  • name -> output.name
  • noConflict -> output.noConflict
  • output.moduleId -> output.amd.id
  • outro -> output.outro
  • paths -> output.paths
  • preferConst -> output.preferConst
  • pureExternalModules -> treeshake.pureExternalModules
  • resolveExternal -> use plugin API
  • resolveId -> use plugin API
  • sourcemap -> output.sourcemap
  • sourceMap -> output.sourcemap
  • sourceMapFile -> output.sourcemapFile
  • strict -> output.strict
  • targets -> use output as an array
  • transform -> use plugin API
  • useStrict -> output.strict
• In general, output options can no longer be used as input options (#2409)
• bundle.generate and bundle.write now return a new format (#2293)
• Several plugin hooks have become deprecated and will display warnings when used (#2409):
  • transformBundle
  • transformChunk
  • ongenerate
  • onwrite
• Plugin transform dependencies are deprecated in favour of using the this.addWatchFile plugin context function (#2409)
• Accessing this.watcher in plugin hooks is deprecated in favour of the watchChange plugin hook and the this.addWatchFile plugin context function (#2409)
• Using dynamic import statements will by default create a new chunk unless inlineDynamicImports is used (#2293)
• Rollup now uses acorn@6 which means that acorn plugins must be compatible with this version; acorn is now external for non-browser builds to make plugins work (#2293)

Features

• The --dir ClI option can now be aliased as -d (#2293)
• The --input option now supports named entry points via = (#2293)

Bug Fixes

• Both the --input option as well as the default CLI option now support named inputs (#2293)

v0.68.0

2018-12-16

Breaking Changes

• optimizeChunks is renamed to experimentalOptimizeChunks to reflect this feature is not production-ready yet (#2575)

Features

• Plugins can iterate all module ids via this.moduleIds (#2565)
• Plugins can get graph information about a module via this.getModuleInfo(id) (#2565)
• Plugins and JS API users get more information about the generated chunks: dynamicImports, facadeModuleId, isDynamicEntry, name (#2575)
• Tree-shaken dynamic imports will no longer create chunks or influence chunking in any way (#2575)
• Dynamic imports will no longer follow the entryFileNames but the chunkFileNames property reflecting those are solely internally used (#2575)
• If there are chunk naming conflicts, entry chunks will always take precedence (#2575)
• If an entry facade is created, only the facade chunk is marked as isEntry (#2575)
• Dynamic chunks will only be marked as isEntry if they are actually entry chunks as well; thus there is now a 1-to-1 correspondence between modules listed in input and chunks marked as isEntry (#2575)
• Chunks no longer contain imports for variables that are tree-shaken in the chunk but used in other chunks (#2584)
• Chunks will always import re-exported variables directly from the chunk where they are originally exported from (#2584)
• Null characters will be pruned from chunk ids to allow for virtually created chunks and make rollup-plugin-multi-entry compatible with code-splitting and thus the upcoming 1.0 version (#2590)
• Simplify the UMD wrapper code as much as possible, especially if there are no exports (#2594)
• The UMD wrapper will now work in strict mode by checking for self before this when determining the global variable (#2594)

Bug Fixes

• If a facade is created for a dynamic entry point, this facade will be imported instead of the facaded chunk (#2575)
• Manual chunks that include multiple entry points will have proper facades created for all entry points if necessary (#2575)
• If missing exports are shimmed, the shim variable will not be global but created on a per-module basis and is deconflicted with variables having the same name (#2584)
• Missing export shims work properly in SystemJS (#2584)
• preserveModules now handles dynamic namespace imports (#2584)
• Fix chunk execution order in certain scenarios (#2584)
• Exports and assignments using destructuring syntax will properly update the exported variables when generating SystemJS output (#2587)
• Hashes in chunk names will now also take dynamic imports into account (#2596)

Pull Requests

• #2565: Provide module graph information on the plugin context (@samccone)
