An Introduction to Redux Saga: Side Effects Made Easier
Sophie Koonin at ReactFest 2018
Not to be confused with insurance policies for the over 50s, redux-saga is a super handy library for managing side effects (such as API calls) in your React app. When used in conjunction with Redux it's a powerful way to fetch data into the state while your main application is executing. Whether or not you've used the saga pattern or related libraries before, this talk will explain what sagas are, how they work, what they're useful for and - the icing on the cake - just how easy they are to test (especially compared to some of the alternatives out there such as redux-thunk). The talk is pitched at developers who are comfortable with React and have at least a baseline knowledge of what Redux does.
