Many of us have products that have been here for a while and are written in older frameworks. Eventually we have to upgrade for various reasons but a full rewrite is a big risk for the company. In this talk we'll learn how to gradually migrate from angularjs to react without hurting the business bottom line. Share data and build hybrid features which are powered both by react and angularjs. Until the final day where we can delete our old code and have a brand new application.
