Hullabaloo Config Manager

1.1.1 verified Sat Apr 25 auth: no javascript maintenance

Version 1.1.1 – Utility to manage complex Babel configuration chains, avoiding duplicated work and enabling effective caching. Built specifically for testing Babel transpilation pipelines, it resolves Babel configs at a project level and caches results to speed up subsequent runs. Differentiates from direct Babel usage by handling multi-step config inheritance and caching internally. Release cadence is low; no updates since 2019. Requires Node >=4.
