# Battle of the Architectures: Dynamic UI with RTK Query vs. Next.js Simplicity

1\. Introduction

When building a modern web application, developers are spoiled for choice with tools and frameworks. On one side, we have **RTK Query** and **React Router**, providing flexibility and control over data fetching and routing. On the other, **Next.js**, a full-stack framework, offers out-of-the-box solutions for routing, server-side rendering (SSR), and static site generation (SSG). In this article, we’ll compare these two architectures and help you decide which one suits your project best.

TldR Table **Comparison:**

| **Feature** | **RTK Query + React Router** | **Next.js** |
| --- | --- | --- |
| Routing | Manual with React Router | File-based routing |
| Data Fetching | RTK Query for client-side fetching | Integrated SSG, SSR, and CSR |
| Rendering | CSR (Client-Side Rendering) | CSR, SSR, SSG, ISR |
| SEO Optimization | Requires tools like React Helmet or SSR setup | Built-in SEO-friendly rendering |
| Setup Complexity | High (manual integration) | Low (built-in features) |

In the ever-evolving world of web development, developers have a plethora of tools and frameworks to choose from when building modern applications. Two popular approaches stand out when working with **React**:

1. **RTK Query + React Router**: A combination of the Redux Toolkit's RTK Query for efficient data fetching and React Router for client-side routing. This architecture provides flexibility and control, making it ideal for applications where customization is key. However, it requires manual integration for features like SEO optimization or server-side rendering.
    
2. **Next.js**: A React-based full-stack framework that simplifies development with features like file-based routing, server-side rendering (SSR), static site generation (SSG), and incremental static regeneration (ISR). It's a go-to solution for applications requiring high performance, built-in SEO optimizations, and ease of use.
    

In this article, we’ll compare these two architectures, exploring their strengths, weaknesses, and when to use each. To ground the discussion, we'll use a blog application as an example.

### **RTK Query + React Router: A Dynamic Approach**

When using **RTK Query** and **React Router**, you manage routing and data fetching independently. Here's how you might implement a blog post page:

```javascript
// BlogPost.js
import { useParams } from 'react-router-dom';
import { useGetBlogPostQuery } from './services/blogApi';

function BlogPost() {
  const { id } = useParams();
  const { data: post, isLoading, error } = useGetBlogPostQuery(id);

  if (isLoading) return <p>Loading...</p>;
  if (error) return <p>Error loading blog post.</p>;

  return (
    <article>
      <h1>{post.title}</h1>
      <p>{post.content}</p>
    </article>
  );
}

export default BlogPost;
```

To make this work:

* **React Router** handles routing:
    

```javascript
import { BrowserRouter as Router, Route, Routes } from 'react-router-dom';
import BlogPost from './BlogPost';

function App() {
  return (
    <Router>
      <Routes>
        <Route path="/blog/:id" element={<BlogPost />} />
      </Routes>
    </Router>
  );
}

export default App;
```

**RTK Query** fetches data dynamically:

```javascript
import { createApi, fetchBaseQuery } from '@reduxjs/toolkit/query/react';

export const blogApi = createApi({
  reducerPath: 'blogApi',
  baseQuery: fetchBaseQuery({ baseUrl: '/api' }),
  endpoints: (builder) => ({
    getBlogPost: builder.query({
      query: (id) => `/posts/${id}`,
    }),
  }),
});

export const { useGetBlogPostQuery } = blogApi;
```

This approach allows for high flexibility but requires additional configuration to optimize SEO, performance, and server-side rendering.

### **Next.js: A Simplified, Full-Stack Framework**

Next.js streamlines the creation of dynamic pages with its file-based routing and built-in data-fetching methods. Here’s how the same blog post page might look:

```javascript
// pages/blog/[id].js
export async function getStaticPaths() {
  const res = await fetch('https://api.example.com/posts');
  const posts = await res.json();

  const paths = posts.map((post) => ({
    params: { id: post.id.toString() },
  }));

  return { paths, fallback: false };
}

export async function getStaticProps({ params }) {
  const res = await fetch(`https://api.example.com/posts/${params.id}`);
  const post = await res.json();

  return {
    props: { post },
  };
}

export default function BlogPost({ post }) {
  return (
    <article>
      <h1>{post.title}</h1>
      <p>{post.content}</p>
    </article>
  );
}
```

In this case:

* **Routing** is handled automatically based on the file structure (`pages/blog/[id].js`).
    
* **Data fetching** is managed through `getStaticProps` and `getStaticPaths`, enabling static generation and prefetching for better SEO and performance.
    

Extended Comparison Table

| **Feature** | **RTK Query + React Router** | **Next.js** |
| --- | --- | --- |
| **Routing** | Manual setup with **React Router**. Example: `<Route path="/blog/:id" element={<BlogPost />} />`. | File-based routing. Example: `pages/blog/[id].js`. |
| **Data Fetching** | Client-side fetching with **RTK Query**, triggered when the page is loaded. | Built-in options for **SSG** (`getStaticProps`), **SSR** (`getServerSideProps`), or **CSR**. |
| **Rendering** | **Client-Side Rendering (CSR)** by default. Requires additional setup for SSR with tools like Express. | Supports **Static Site Generation (SSG)**, **Server-Side Rendering (SSR)**, and hybrid rendering. |
| **SEO** | Needs tools like **React Helmet** or SSR for better SEO. | Native SEO optimizations with server-side rendering and static generation. |
| **Performance** | Requires manual lazy loading and optimization for images and assets. | Built-in optimizations like automatic image optimization and page prefetching. |
| **API Integration** | Requires a separate backend for API endpoints (e.g., Express, Koa). | API routes built into the framework under `pages/api/`. |
| **Ease of Use** | More configuration and boilerplate code for routing, data fetching, and SSR setup. | Simplified setup with ready-to-use features. |
| **Flexibility** | Highly flexible. You can use only the libraries and features you need. | Opinionated and less flexible, but includes everything needed for a full-stack application. |

### **Comparison in Context**

* With **RTK Query + React Router**, you have full control over the architecture but must manually address concerns like server-side rendering and SEO.
    
* With **Next.js**, these features are built-in, making it easier to create a high-performance, SEO-friendly blog application with less manual effort.
    

### **Real-World Scenarios**

#### **When to Use RTK Query + React Router**

* **Highly Customized Applications**:
    
    * If your application requires unique routing logic or a custom data-fetching strategy, this architecture gives you full control.

* **Full-Stack Projects**:
    
    * Suitable when you want to combine front-end and back-end in a single project, using API routes for backend logic.
        

**Example Scenario**: A multi-author blog platform that needs to pre-render posts for SEO and load quickly with static pages.

```javascript
// pages/blog/[id].js
export async function getStaticProps({ params }) {
  const post = await fetch(`https://api.example.com/posts/${params.id}`).then((res) => res.json());
  return { props: { post } };
}
