@rollup/plugin-babel changelog

5.0.0

2020-04-27

Features

  • Added getBabelOutputPlugin and createBabelOutputPluginFactory exports which can be used to transform generated code
  • Added skipPreflightCheck option. The plugin performs some extra checks to see if the passed configuration is correct and matching its expectations. This comes with some runtime overhead and can slow down builds. If you know what you are doing and you are confident that you have configured things correctly you can disable those checks with this option.
  • Published as @rollup/plugin-babel

Updates

  • Default export exported as getBabelInputPlugin for symmetry with getBabelOutputPlugin

Breaking Changes

  • Minimum compatible Rollup version is 1.2.0
  • Minimum supported Node version is 10.0.0
  • .custom factory is now available as separate createBabelInputPluginFactory export
  • Removed externalHelpers & runtimeHelpers options. There is now a single babelHelpers option which can take one of 'bundled', 'inline', 'runtime' and 'external' as a value. The default is 'bundled' which matches 4.x behavior, but it is recommended to configure this option explicitly.

4.3.2

  • Fixed usage with externalHelpers: true option

4.3.1

  • Add .js extension to the virtual babel helpers file (only matters when using preserveModules option in rollup)

4.3.0

  • Added .custom builder.
  • Fail build when a plugin tries to add non existent babel helper

4.2.0

Allow rollup@1 as peer dependency.

4.1.0

  • Fixed "preflight check" for ignored files.
  • Return null when no transformation has been done (fixing source maps for this case)

4.0.3

Fixed fallback class transform in "preflight check".

4.0.2

Fixed rollup peer dependency.

4.0.0

Babel 7 compatible! (dropped Babel 6 compatibility though).

Additionally:

  • Internal preflight checks are created now per plugin instance, so using 2 instances of rollup-plugin-babel (i.e. targeting 2 different set of files with include/exclude options) shouldn't conflict with each other
  • Transpiling by default only what Babel transpiles - files with those extensions: .js, .jsx, .es6, .es, .mjs. You can customize this with new extensions option. This also fixes long standing issue with rollup-plugin-babel trying to transform JSON files.

3.0.3

  • Drop babel7 support. Use 4.0.0-beta if you use babel 7
  • Use "module" in addition to "jsnext:main" (#150)
  • Remove unused babel helpers namespace declaration & expression (#164)

3.0.2

  • Fix regression with Babel 6 (#158)

3.0.1

  • Wasn't working, fix bug with transform (not using es2015-classes for preflight check)

3.0.0

  • Drop Node 0.10/0.12 (Use native Object.assign)
  • Change babel-core to be a peerDependency
  • Support babel-core v7 as well as a peerDep (no changes necessary)

2.7.1

  • Prevent erroneous warnings about duplicated runtime helpers (#105)
  • Ignore ignore option in preflight check (#102)
  • Allow custom moduleName with runtime-helpers (#95)

2.7.0

  • Add externalHelpersWhitelist option (#92)
  • Ignore only option during preflight checks (#98)
  • Use options.onwarn if available (#84)
  • Update documentation and dependencies

2.6.1

  • Return a name

2.6.0

  • Use \0 convention for helper module ID (#64)

2.5.1

  • Don't mutate options.plugins (#47)

2.5.0

  • Import babelHelpers rather than injecting them – allows transform function to be pure (#rollup/658)

2.4.0

  • Add externalHelpers option (#41)

2.3.9

  • Do not rename Babel helpers (#34)

2.3.8

  • Create new version to (hopefully) solve bizarre CI issue

2.3.7

  • Be less clever about renaming Babel helpers (#19)

2.3.6

  • Fix cache misses in preflight check (#29)

2.3.5

  • Use class transformer local to plugin, not project being built

2.3.4

  • Ensure class transformer is present for preflight check, and only run check once per directory (#23)

2.3.3

  • Fix helper renaming (#22)

2.3.1-2

  • Include correct files in npm package

2.3.0

  • Allow transform-runtime Babel plugin, if combined with runtimeHelpers: true option (#17)
  • More permissive handling of helpers – only warn if inline helpers are duplicated
  • Handle plugins that change export patterns (#18)

2.2.0

  • Preflight checks are run per-file, to avoid configuration snafus (#16)
