broccoli-babel-transpiler

A Broccoli plugin for transpiling ES6+ to readable ES5 using Babel, with caching and parallelization. Current stable version 8.0.2 supports Node 16+ and 18+ and requires @babel/core >=7.17.9 as a peer dependency. Key differentiators include persistent caching across rebuilds (via cacheKey/cacheKeyPlugin methods) and async plugin support since v8.0.1. Notable breaking changes in v8 include dropping Node 14 and moving @babel/core to peer deps. Commonly used in Ember.js and other Broccoli-based build pipelines.
