broccoli-sabel

0.3.6 verified Fri May 01 auth: no javascript deprecated

Broccoli plugin for simple Babel transpilation (sabel is a lightweight Babel wrapper). Version 0.3.6 is the latest, but the package appears unmaintained (last release years ago). It provides a thin layer for running Babel transforms within Broccoli builds, but alternatives like broccoli-babel-transpiler or direct use of Babel are recommended for active support.

Quickstart

Creates a Broccoli tree that transpiles files in 'src' using Babel with @babel/preset-env and source maps.

import sabel from 'broccoli-sabel';
import { writeFileSync } from 'fs';

const tree = sabel('src', {
  presets: ['@babel/preset-env'],
  sourceMaps: true
});

// In Brocfile.js or similar, return tree
export default tree;
