Building large scale apps in the last years, lead me to a development process that provides rapid results and ability to scale. I want to show these technics, building a real world react app, using storybook, with DDD (design-driven development) and atomic design. Building an app is a complicated task. It starts with the flow from the product moving to design and then to the RND. However, it does not stop there, there is a need to go back and forth with the process as specs and design might change. Using DDD, we can leverage the ability to describe the spec visually, for the product and other stakeholders. Using atomic design, we can create our MVP fast and ready for scale. Oppose to design systems, Atomic design gives us the granularity we need, and a way to compose our app parts very fast and stable.
