Exploring Redux Toolkit 2.0 and the Redux second generation

State management in web applications continues to be a crucial consideration, with Redux maintaining its prominent position despite alternatives like React’s Context API and MobX. Redux Toolkit, introduced in 2019, has streamlined Redux’s previously complex boilerplate, becoming the standard for creating Redux apps by simplifying state management processes. The release of Redux Toolkit 2.0 in November 2023 marks a significant update, offering modernization, deprecations, and improved workflows with new features like the combineSlices method for lazy loading and code-splitting, dynamic middleware addition, and enhanced TypeScript compatibility. The toolkit now requires TypeScript 4.7 and React Redux 9.0 for optimal performance, ensuring minimal impact on end users despite some breaking changes. RTK Query 2.0, part of the update, focuses on refining data fetching capabilities by addressing specific bugs and improving tag invalidation. The updates further simplify Redux usage by reducing boilerplate and integrating modern software practices, encouraging developers to transition from traditional Redux approaches.
