Simplifying Global State in React: Using useContext and useReducer Together

React is incredibly powerful for building UI components, but managing global state across deeply nested components can get tricky. While libraries like Redux exist for complex scenarios, React provides two built-in hooks — useContext and useReducer—that together can give you a clean, scalable solution for state management without external dependencies.

In this post, you’ll learn:

• What useContext and useReducer are
• Why you might want to use them together
• How to set them up with a real-world example

What is useContext

What is useReducer?

The useReducer hook is a more powerful alternative to useState for managing complex state logic.

It’s similar to how Redux works:
You define a reducer function to describe how state changes in response to actions.

const reducer = (state, action) => {
  switch (action.type) {
    case 'increment':
      return { count: state.count + 1 }
    default:
      return state
  }
}

const [state, dispatch] = useReducer(reducer, { count: 0 })

Why Combine useContext + useReducer?
