eustia-babel

0.0.1 verified Fri May 01 auth: no javascript deprecated

Babel transpiler plugin for the Eustia utility library generator. Version 0.0.1 provides a handler that transpiles ES6+ files via Babel presets within Eustia's build pipeline. It requires manual installation of presets (e.g., babel-preset-es2015) and is tightly coupled to Eustia's configuration format. No active development or updates observed; the package is essentially a thin wrapper around Babel, with no versions beyond 0.0.1. Alternative: use Babel directly.

Common errors

error Error: Cannot find module 'babel-preset-es2015' ↓

cause Missing required Babel preset.

fix

Run: npm install babel-preset-es2015

error TypeError: handler is not a function ↓

cause Using .default import syntax on a CommonJS factory export.

fix

Change to: handler: require('eustia-babel')({presets: ['es2015']})

error Module build failed: TypeError: config.presets[0] is not a function or plugin ↓

cause Using newer Babel version or preset format incompatible with this plugin's expectations.

fix

Ensure Babel core and preset versions match; consider switching to @babel/preset-env.

Warnings

deprecated Package is unmaintained and relies on deprecated Babel presets (babel-preset-es2015). ↓

fix Migrate to @babel/preset-env directly or use a maintained Eustia plugin.

breaking Requires explicit installation of Babel presets; missing preset will cause runtime error. ↓

fix Install required presets: npm install babel-preset-es2015

gotcha The package exports a factory function, not an object with a default export. Common mistake: using import or .default. ↓

fix Use require('eustia-babel') directly, not require('eustia-babel').default

Install

npm install eustia-babel

yarn add eustia-babel

pnpm add eustia-babel

Imports

default

wrong

import eustiaBabel from 'eustia-babel';

correct

const eustiaBabel = require('eustia-babel');

CommonJS module; no default ESM export available.

transpiler handler

wrong

handler: require('eustia-babel').default({presets: ['es2015']})

correct

handler: require('eustia-babel')({presets: ['es2015']})

The package exports a factory function directly, not an object with a default property.

options

const options = {presets: ['es2015']}; const handler = require('eustia-babel')(options);

Options are passed as a plain object; see Babel documentation for available options.

Quickstart

Example Eustia configuration using eustia-babel to transpile .es6 files with the es2015 preset.

// In your Eustia config file (e.g., eustia.config.js)
module.exports = {
  util: {
    files: 'index.html',
    extension: ['js', 'es6'],
    transpiler: [
      {
        test: /\.es6$/,
        handler: require('eustia-babel')({
          presets: ['es2015']
        })
      }
    ]
  }
};
