rollup-plugin-buba

1.0.1 verified Mon Apr 27 auth: no javascript maintenance

A Rollup plugin for buba, a fast ES6-to-ES5 transpiler similar to Bublé. Version 1.0.1 is the latest release. It wraps buba to transform ES6+ modules during Rollup bundling. Simpler than Babel-based plugins but limited to experimental support. Not actively maintained.

Common errors

error Error: Cannot find module 'rollup-plugin-buba' ↓

cause Package not installed or not in node_modules

fix

Run 'npm install rollup-plugin-buba --save-dev'

error TypeError: buba is not a function ↓

cause Incorrect import pattern: using named import instead of default

fix

Use 'import buba from "rollup-plugin-buba"' instead of '{ buba }'

error Error: Invalid plugin object returned from function ↓

cause Plugin returns undefined due to buba not installed

fix

Ensure buba is installed alongside rollup-plugin-buba: 'npm install buba'

Warnings

deprecated buba is in maintenance mode and may not support latest JavaScript features ↓

fix Consider using @rollup/plugin-babel or @rollup/plugin-sucrase for active support.

gotcha Plugin does not accept many options; only 'include', 'exclude', and buba options ↓

fix Check buba documentation for supported options; pass them directly to buba() config object.

gotcha Rollup version compatibility: may not work with Rollup 2+ due to plugin API changes ↓

fix If using Rollup 2+, upgrade to a maintained alternative like @rollup/plugin-babel.

Install

npm install rollup-plugin-buba

Imports

default
wrong
```
const buba = require('rollup-plugin-buba')
```
correct
```
import buba from 'rollup-plugin-buba'
```
Package exports default only; CJS users should use dynamic import or use ESM.

buba

wrong

import { buba } from 'rollup-plugin-buba'

correct

import buba from 'rollup-plugin-buba'

Named import is not supported; use default import.

rollupConfigExport
wrong

module.exports = { plugins: [buba()] }
```
correct
```
export default { plugins: [buba()] }
```
Rollup config uses ESM export; CJS module.exports not directly supported.

Quickstart

Shows basic Rollup config using rollup-plugin-buba to transpile ES6 input, excluding node_modules.

// rollup.config.js
import buba from 'rollup-plugin-buba';

export default {
  input: 'src/index.js',
  output: {
    file: 'dist/bundle.js',
    format: 'iife'
  },
  plugins: [
    buba({
      exclude: 'node_modules/**'
    })
  ]
};
