Redux vs Zustand: A Comprehensive Comparison

Overview of State Management in React

Redux (Detailed Explanation):

Architecture:

  • Store: Central state holder for entire application
  • Action: Events for state changes
  • Reducer: Pure functions creating new state

Complexity:

  • Significant boilerplate code
  • Steeper learning curve
  • Supports middleware like Redux Thunk, Redux Saga
  • Full state tracking with DevTools

Use Cases:

  • Large enterprise-level applications
  • Complex state logic
  • Real-time applications
  • Multi-layer applications

Zustand (Detailed Explanation):

Architecture:

  • Simple hook-based state management
  • Minimal configuration
  • Supports immediate mutation
  • Native React hooks-like syntax

Advantages:

  • Extremely lightweight (only 1.5kb)
  • Less code to write
  • High performance
  • Easy asynchronous operations

Use Cases:

  • Small to medium applications
  • React projects
  • Rapid prototyping
  • Simple state management

Code Comparison

Redux Example:

// Redux Store
const initialState = { count: 0 }
function counterReducer(state = initialState, action) {
  switch (action.type) {
    case 'INCREMENT':
      return { count: state.count + 1 }
    default:
      return state
  }
}
Enter fullscreen mode Exit fullscreen mode

Zustand Example:

import create from 'zustand'

const useCounterStore = create((set) => ({
  count: 0,
  increment: () => set((state) => ({ count: state.count + 1 }))
}))
Enter fullscreen mode Exit fullscreen mode

Key Differences:

  1. Redux: More control, complex
  2. Zustand: Simple, less code

When to Choose?

Use Redux When:

  • Building large applications
  • Complex state logic required
  • Team project
  • Multiple middleware needed

Use Zustand When:

  • Small to medium applications
  • Simple state management
  • Rapid prototyping
  • Minimal boilerplate desired

Conclusion

As a software architect, choose the technology based on project size and complexity.

Best Practices:

  • Evaluate project requirements
  • Consider team expertise
  • Analyze performance needs
  • Plan for future scalability
