Hello everyone,\n\nI am new to Apache Superset and I want to know more about its code structure since I want to make a contribution sometime in the future.\n<https://github.com/apache/incubator-superset/tree/master/superset-frontend/src>\nI've been looking into this directory in the master branch to investigate its front-end components.\nI know it's built using React. However, I am not familiar with how the project is structured. It has multiple folders that have\u00a0`App.js`. I always thought there would only be one\u00a0`App.js`\u00a0in a React project. How does this work?\nAlso, I would like to know how all these components get together and form the Superset frontend. It would be great to know how these components depend on each other. (e.g. How does\u00a0`explore`\u00a0work with\u00a0`chart`, etc.)\n\nThank you for the great open-source project. I am looking forward to learning more.
