React Router v7 Practical Guide

React Router v7 brings many exciting new features, let's explore these improvements together.

Main New Features

1. Simplified Route Configuration

The new version provides a more concise way to configure routes:

import { type RouteConfig, index, route } from "@react-router/dev/routes";

export default [
  index("routes/home.tsx"),
  route("about", "routes/about.tsx"),
] satisfies RouteConfig;

2. Improved Type Support

v7 provides better TypeScript support, including auto-generated type definitions.

3. Performance Optimizations

• Better code splitting
• Optimized preloading mechanism
• Reduced bundle size

Best Practices

1. Use File System Routing: Leverage convention over configuration principles
2. Proper Use of Loaders: Preload data at the route level
3. Error Boundaries: Add appropriate error handling for each route

React Router v7 is a powerful upgrade, worth learning and using for every React developer.
