create-react-app is a great example of a project that abstracts away all the complexities of a JavaScript build process and dev environment, but customization inevitably requires you to 'eject' and reintroduce that complexity to your project.
This tool goes one step further and supports customization without this eject step.
This is finally where web builds need to be to provide a simple foundation for modern web development so devs can focus more on making apps and less on tooling.
I look forward to trying it out.
