Creating a living design system is essential to developing a cohesive experience for users over the lifetime of a product. Ember tooling and conventions make this easier than you might expect. By organizing your application functionality into Ember components, you can easily build a living style guide to showcase key features, design patterns, and user interactions. This fashion of style guide driven development enables a rapid implementation and feedback cycle, a comprehensive overview of key features, and the blissful feeling of providing order in a chaotic world.
