broccoli-6to5-transpiler

library3.0.0jsnpmunverified

This package is deprecated. It was the Broccoli plugin for transpiling ES6 to ES5 using 6to5 (the original name of Babel). The project has been renamed and migrated to `broccoli-babel-transpiler`, which is actively maintained with the latest version v8.0.2 (January 2025). The current package (broccoli-6to5-transpiler) is archived and should not be used. Instead, use `broccoli-babel-transpiler` with `@babel/core` as a peer dependency. Key differentiator: it integrates Babel into the Broccoli build system, supporting Babel plugins and presets, but this deprecated version is incompatible with modern Babel (v7+).

Verified usage

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

default

✓ import transpile from 'broccoli-babel-transpiler';

✗ const transpile = require('broccoli-6to5-transpiler');

The package was renamed to 'broccoli-babel-transpiler'. Do not use the old name 'broccoli-6to5-transpiler'. Use default import (or require).

BroccoliBabelTranspiler

✓ import BroccoliBabelTranspiler from 'broccoli-babel-transpiler';

✗ const BroccoliBabelTranspiler = require('broccoli-6to5-transpiler');

The new package name is 'broccoli-babel-transpiler'. This is the default export.

options

✓ import transpile from 'broccoli-babel-transpiler'; const tree = transpile('lib', { presets: [['@babel/preset-env', { targets: { node: 'current' } }]] });

✗ const tree = require('broccoli-6to5-transpiler')('lib', { blacklist: ['es6.classes'] });

The options format changed from 6to5 style (e.g., 'blacklist') to Babel 7+ style (e.g., 'presets', 'plugins'). The old 'blacklist' option is deprecated; use 'exclude' in preset-env.

Demonstrates how to transpile ES6+ JavaScript with Babel in a Broccoli build pipeline using the current 'broccoli-babel-transpiler' package, not the deprecated 'broccoli-6to5-transpiler'.

// Correct usage with broccoli-babel-transpiler (NOT the deprecated broccoli-6to5-transpiler) // Brocfile.js import { createBuilder, createWatcher } from 'broccoli'; import transpile from 'broccoli-babel-transpiler'; import funnel from 'broccoli-funnel'; const app = 'src'; const scripts = funnel(app, { include: ['**/*.js'] }); const transpiled = transpile(scripts, { presets: [ ['@babel/preset-env', { targets: { browsers: ['last 2 versions'] }, modules: false }] ] }); const builder = createBuilder(transpiled); // Export or use the builder as needed export default transpiled;

affects: >=0

breaking6to5 options (e.g., 'blacklist', 'optional') are not supported in Babel 7+. Using them will cause errors.

fix

Use Babel 7+ configuration: 'presets', 'plugins', 'targets' instead of 6to5-specific options.

affects: >=8.0.0

breakingSince v8.0.0, @babel/core must be installed as a peer dependency. Missing it leads to 'Cannot find module @babel/core'.

fix

Install @babel/core: npm install --save-dev @babel/core

affects: >=8.0.0

breakingNode.js 14 support is dropped in broccoli-babel-transpiler v8.0.0. The package may fail on Node 14.
