This is a demo project showing how to leverage the changes in [email protected] that allows an application (or addon) to use a babel.config.js instead of relying on "magical" configuration by ember-cli-babel itself.

The main changes are:

• Update to [email protected]
• Add babel.config.js file (with very basic config)
• Install @babel/preset-env
• Install @babel/eslint-parser
• Update ember-cli-build.js
  • Opt in to useBabelConfig: true API
  • Temporarily work around ef4/ember-auto-import#342 by adding qunit to skipBabel configuration in ember-cli-build.js
• Update .eslintrc.js
  • Add babel.config.js to list of "node" files
  • Change parser to @babel/eslint-parser
