2# or
3yarn add @tanstack/router

​

Once installed, you can integrate TanStack Router into your React application. The setup is straightforward. For example, here is a simple configuration in TypeScript:

1import React from 'react';
2import {
3  RouterProvider,
4  createReactRouter,
5  createRouteConfig
6} from '@tanstack/router';
7
8const routeConfig = createRouteConfig([
9  {
10    path: '/',
11    element: <HomePage />,
12    errorElement: <ErrorPage />,
13  },
14  {
15    path: '/about',
16    element: <AboutPage />,
17  },
18]);
19
20const router = createReactRouter({ routeConfig });
21
22const App = () => (
23  <RouterProvider router={router}>
24    <YourAppLayout />
25  </RouterProvider>
26);
27
28export default App;

​

This basic setup demonstrates how TanStack Router offers instant navigations with built features, making route transitions seamless and efficient.

Core Concepts and Built in Data Fetching

At its core, TanStack Router excels through its intuitive route configurations and built in data fetching. One of its most appealing features is the integration of data fetching with caching, enabling fetching stale while revalidate patterns out of the box. This means you get stale while revalidate caching that minimizes wait times by serving cached content and then updating in the background.

The router’s built in data fetching mechanism allows you to define loaders directly within your route configurations, supporting caching and automatic preloading. This approach not only improves performance but also ensures that data fetching is typesafe and consistent across your application.

Defining Routes and URL State Management

Defining routes in TanStack Router is a declarative process. You specify routes with associated components, and the router handles URL state management seamlessly. The library makes it easy to create complex nested routes and dynamic segments. For instance:

1import { createRouteConfig } from '@tanstack/router';
2
3const routeConfig = createRouteConfig([
4  {
5    path: '/',
6    element: <HomePage />,
7  },
8  {
9    path: '/products',
10    element: <ProductsPage />,
11    children: [
12      {
13        path: '/:productId',
14        element: <ProductDetailsPage />,
15      },
16    ],
17  },
18]);

​

In this example, the router not only manages the component rendering but also supports a first class search param mechanism. With param apis to make custom search param pre post processing, you can create a route pop that handles even the most complex query strings. This attention to detail in URL state management is a behold the obligatory feature for modern web applications.

Navigation and Dynamic Routing

Navigation within TanStack Router is both flexible and powerful. The library provides hooks such as useNavigate to programmatically manage route changes. Consider this example:

1import { useNavigate } from '@tanstack/router';
2
3const SomeComponent = () => {
4  const navigate = useNavigate();
5
6  const handleClick = () => {
7    navigate('/about');
8  };
9
10  return <button onClick={handleClick}>Go to About Page</button>;
11};

​

Dynamic routes are supported natively, allowing you to leverage class search param apis to make search param pre post adjustments automatically. This design allows for param pre post processing which ensures that the URL is always in sync with the state of your application. Such robust support for dynamic routing and search param parsing serialization makes TanStack Router a react router with built features that adapt to your needs.

Advanced Features: Caching and Automatic Preloading

TanStack Router doesn't stop at basic routing; it introduces advanced features like caching and automatic preloading to enhance user experience. These include:

• Caching and first class: Direct integration of caching strategies that enable fetching stale while revalidate, ensuring users always see up-to-date content.

• Automatic preloading: Preloads components and data ahead of time, reducing wait times during navigation.

• Data fetching with caching: Combines efficient data retrieval with the benefits of stale while revalidate caching to optimize performance.

These features are ideal if you want to build a state manager jealous of your application's efficiency. Additionally, they enable revalidate caching and first class search param operations, ensuring that even complex data fetching patterns are handled gracefully.

Integration with React and TypeScript

One of the key advantages of TanStack Router is its smooth integration with React and TypeScript. This integration ensures that your routing logic is both typesafe and powerful yet familiarly straightforward. Here’s a snippet that illustrates a TypeScript-based route configuration with asynchronous data loaders:

1import React from 'react';
2import {
3  createReactRouter,
4  RouterProvider,
5  createRouteConfig
6} from '@tanstack/router';
7
8interface ProductData {
9  id: string;
10  name: string;
11}
12
13const routeConfig = createRouteConfig([
14  {
15    path: '/',
16    element: <HomePage />,
17    loader: async (): Promise<ProductData[]> => {
18      const response = await fetch('/api/products');
19      return response.json();
20    },
21  },
22  {
23    path: '/product/:id',
24    element: <ProductDetailPage />,
25    loader: async ({ params }): Promise<ProductData> => {
26      const response = await fetch(`/api/products/${params.id}`);
27      return response.json();
28    },
29  },
30]);
31
32const router = createReactRouter({ routeConfig });
33
34const App: React.FC = () => (
35  <RouterProvider router={router}>
36    <YourAppLayout />
37  </RouterProvider>
38);
39
40export default App;

​

This configuration is a prime example of routing for React applications that leverages built in data fetching, allowing for caching and automatic preloading while maintaining URL state management with safety and pre post measures.

Understanding Search Param APIs

TanStack Router excels with its support for first class search param capabilities. The library offers class search param apis that allow you to perform search param pre post processing with ease. These apis facilitate search param parsing serialization, making it effortless to maintain URL query strings. This is particularly useful for dynamic filtering and state management.

The search param pre post feature allows developers to inject custom logic before and after search parameters are processed, ensuring safety and pre post validations are applied. These robust capabilities mean you can make your state manager jealous by having a full-fledged system that handles even the most intricate URL manipulations automatically.

Best Practices and Performance Enhancements

To get the best performance out of TanStack Router, consider these best practices:

• Modular Route Definitions: Organize routes into separate modules to maintain clarity and scalability.

• Lazy Loading: Implement caching and automatic preloading to speed up initial page loads.

• Error Handling: Incorporate error boundaries and loaders to gracefully manage failed data fetches.

• Optimization with Caching: Utilize stale while revalidate caching strategies to minimize downtime and ensure your application remains responsive.

Remember, building on modern routing means that you not only create a route pop that is efficient but also maintain instant navigations with built smooth transitions. These practices, combined with advanced features such as fetching stale while revalidate, ensure that your application remains modern and scalable.
