| State Type | Solution | Example | |------------|----------|---------| | | TanStack Query (React Query) + fetch | List of users, product details | | URL state | React Router | Query params, route params | | Client global state | Zustand / Redux Toolkit | User session, theme preference | | Local UI state | useState / useReducer | Form input, modal open/close |
apiClient.interceptors.response.use( (res) => res, async (error) => if (error.response?.status === 401) // redirect to login
Scaling a React application from a simple prototype to a production-ready environment requires a strategic shift in how you organize code, manage state, and handle data. A robust architecture ensures that the application remains maintainable, performant, and easy to debug as it grows. 1. Modular and Feature-Based Folder Structure react application architecture for production pdf
Catch JavaScript errors in components without crashing the whole app:
The transition from developing a React application in a local development environment to deploying it to a production environment represents a significant shift in engineering priorities. While initial development focuses on feature velocity and functionality, production architecture demands a focus on stability, scalability, security, and performance. This essay outlines the fundamental pillars of a robust React production architecture, exploring project structure, state management, performance optimization, and operational concerns necessary for enterprise-grade applications. | State Type | Solution | Example |
// app/router/index.tsx import createBrowserRouter from 'react-router-dom'; import lazy, Suspense from 'react';
componentDidCatch(error: Error, info: React.ErrorInfo) console.error('Uncaught error:', error, info); // Send to monitoring service (Sentry, LogRocket) // app/router/index
);
