Mark Erikson and Lenz Weber-Tronic are long-time Reactiflux members and maintainers of Redux. Event MC'd by Carl Vitullo, and hosted on Reactiflux. Mark (@acemarke) has been primary maintainer of Redux for 6 years and led development of Redux Toolkit, which was a major step forward in usability for the ecosystem. He's approaching the end of his first year in a new role at Replay.io, a time-traveling browser debugger. Before that, he spent the majority of his career — over 13 years — at 1 company!  Lenz (@phryneas) has been a software developer for 20 years, and has worked with Mark as a maintainer of Redux and Redux Toolkit since 2019. He contributed much of the TypeScript expertise that made RTK possible, and is the brains behind RTK Query. He's in the middle of changing jobs right now, from a consultancy in Berlin to Apollo, a well-known open source company. We talk about maintaining an open source library (and the challenges of providing correct TypeScript types!), what a job search is like later in your career, and more. Some links referenced through the discussion: Hyrum's Law Learning and Using TypeScript as an App Dev and a Library Maintainer Why React Context is Not a "State Management" Tool (and Why It Doesn't Replace Redux) If you found this valuable, one way you can help support Reactiflux is through buying one of the books we recommend!
