lab-babel

A transform for the lab test framework that enables testing of ES6/JSX modules transpiled with Babel, including code coverage and proper source maps. Current version: 1.1.1 (stable, low activity). This package integrates with lab's -T option to automatically transpile .js, .jsx, .es, and .es6 files (excluding node_modules) using Babel, preserving source maps for accurate error line numbers. Key differentiator: legacy dependency on babel-core (>=4.x.x); not intended for Babel 6+ without manual preset configuration (babel-preset-es2015). Not actively maintained; consider modern alternatives like @babel/register or ts-node.
