babel-pundle

1.1.12 verified Sat Apr 25 auth: no javascript deprecated

Babel transformer plugin for Pundle, a JavaScript bundler. Version 1.1.12 is the latest stable release, with v2.0.0-alpha1 introducing breaking architectural changes. This plugin enables Babel transformations within Pundle's build pipeline, supporting custom Babel configuration, file extension filtering, and ignore patterns. Key differentiators: integrates deeply with Pundle's plugin system, but is deprecated in favor of Pundle's built-in Babel support in v2. No active maintenance since 2017.

Warnings

deprecated babel-pundle is deprecated in favor of Pundle's built-in Babel support in v2+ ↓

breaking Breaking change: v2.0.0-alpha1 changes plugin API; v1.x plugins are incompatible ↓

fix Do not upgrade to v2 alpha unless you can adapt to new component/preset architecture

gotcha Common mistake: using plugin name string instead of require.resolve() path ↓

fix Use require.resolve('babel-pundle') to get the absolute path

Imports

default export
wrong
```
const babelPundle = require('babel-pundle')
```
correct
```
import babelPundle from 'babel-pundle'
```

plugin usage

wrong

pundle.loadPlugins([['babel-pundle', { ignore: ... }]])

correct

pundle.loadPlugins([[require.resolve('babel-pundle'), { config: { ... } }]])

Must use require.resolve() and pass options as second array element.

type import
```
import type { PluginOptions } from 'babel-pundle'
```
TypeScript types may not be bundled; declare your own interface.

Quickstart

Loads the babel-pundle plugin, configures Babel with preset-env, ignores node_modules, and bundles an entry file.

const pundle = require('pundle');
pundle.loadPlugins([
  [require.resolve('babel-pundle'), {
    ignored: /node_modules/,
    extensions: ['.js', '.jsx'],
    config: {
      presets: ['@babel/preset-env']
    }
  }]
]).then(() => console.log('Plugin loaded'));
pundle.bundle('./src/index.js').then(result => {
  console.log(result.code);
});
