The first moment I started developing on the platform I was excited about the ease with which I got into things, the order and organization of the code. It is evident that amazing architectural work has been done here from developer to developer. There is full use of React's with Typescript and full of best practices, including a storybook of an efficient and useful collection of components. highly recommend!

I was so inspired when I found Common Ninja. It fills a gap that’s missing when building cross-platform plugins and solves many complexities. Overall, it just makes plugins development fun and fast, so you can build more!
