Next.js — Setting up a Redux store with combineReducers()

Redux is one of the most common libraries for state management in React projects. Here is a short guide about setting up a Redux store with combineReducers() in your Next.js project. This is a guide for beginners. If you have been playing with Next.js for a while, you probably don’t need this guide. Yet, I don’t find many people talking about this from Google. Hence, I would like to provide some sample codes. In case you just start to use Next.js, I hope this can be a starter for you to quickly begin with and save you some hours from studying it.
