The Lean Startup advocates an iterative approach to finding the right product and market, with a constant cycle of building, measuring and learning. Lean Analytics is a new approach which dives deeper into the measurement component of this process. With Lean Analytics we can measure the state of the application and make informed decisions about the product and its vision based on end user interactions. Redux allows us to maintain our application state in a single store, and provides a single location for state changes. By hooking analytics into this event loop we can infer a lot about end user behaviour. Our Redux Segment middleware allows you to draw deep and rich analytics from your Redux application with minimal configuration. In this talk, we will walk through the process of adding analytics to your existing Redux application and share our implementation which works with segment.io.
