rollup-plugin-simple-babel

library1.0.6jsnpmunverified

A simple Rollup plugin that wraps Babel to allow seamless transpilation during bundling. Version 1.0.6 (latest as of early 2019) is stable but low maintenance. It passes all Babel options through via the plugin invocation. Unlike @rollup/plugin-babel, it does not automatically select files or require Babel configuration; it transforms all JavaScript files. Recommended only for trivial setups; most projects should use @rollup/plugin-babel for better integration, performance, and automatic detection of Babel configs.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

babel

✓ import babel from 'rollup-plugin-simple-babel'

✗ import { babel } from 'rollup-plugin-simple-babel'

Default export only; named import will break. CJS: const babel = require('rollup-plugin-simple-babel').default

babel()

✓ plugins: [babel()]

✗ plugins: [babel({...})] without calling as function

Must invoke as a function; passing options object directly will be ignored.

babel({presets: [...]})

✓ plugins: [babel({ presets: ['@babel/preset-env'] })]

✗ plugins: [babel({presets: ['env']})]

Preset names must be full package names (e.g., '@babel/preset-env'), not short names. Babel 7+ requires @babel/ scoped packages.

Minimal Rollup config using rollup-plugin-simple-babel with Babel presets and plugins.

// rollup.config.js import babel from 'rollup-plugin-simple-babel'; import resolve from '@rollup/plugin-node-resolve'; export default { input: 'src/main.js', output: { file: 'dist/bundle.js', format: 'cjs' }, plugins: [ resolve(), babel({ presets: ['@babel/preset-env'], plugins: ['@babel/plugin-transform-runtime'] }) ] };

Debug

Known issues

gotchaBy default, this plugin transforms all files; no 'include' or 'exclude' filtering.

fix

Use @rollup/plugin-babel which supports filtering and is actively maintained.

affects: >=1.0.0

deprecatedPackage is no longer actively maintained; use @rollup/plugin-babel instead.

fix

Migrate to @rollup/plugin-babel: npm install @rollup/plugin-babel --save-dev

affects: >=1.0.0

breakingRequires Babel 7+; does not work with Babel 6.

fix

Ensure @babel/core and Babel presets/plugins are installed as devDependencies.

affects: >=1.0.0

gotchaDoes not read Babel configuration from .babelrc or babel.config.js automatically; you must pass options via plugin.

fix

Duplicate Babel options in rollup.config.js or use @rollup/plugin-babel which respects babel config files.

affects: >=1.0.0

gotchaPackage exports a single default function; named import (import { babel }) is undefined.

fix

Use default import: import babel from 'rollup-plugin-simple-babel'

affects: >=1.0.0
