React apps are great for building dynamic user interfaces, but when it’s time to scale up performance, it’s Next.js to the rescue. If you’re looking to move React app to NextJS, this guide will walk you through the process step-by-step. From handling React components to configuring server-side rendering, let’s dive into the transition and unlock faster page loads, better SEO, and a smoother development flow.
Overview: What is Next.js?
Next.js is like the superhero of React frameworks. It takes everything we love about React—like building interactive UIs—Next.js enhances everything we love about React—like building dynamic UIs (to clarify how ReactJS works, it efficiently updates the UI using a virtual DOM)—and adds some powerful extras, such as server-side rendering (SSR) and static site generation (SSG), which help boost performance and SEO. Essentially, it makes web apps faster and more scalable right out of the gate.
One of the standout features of Next.js is its ability to combine client-side and server-side rendering, allowing you to choose the best approach for each page. That means faster load times and a smoother user experience. In React, similar responsiveness and speed are often achieved through React WebSocket API, which enables real-time updates and seamless interactions. Plus, Next’s file-based routing system makes navigation a breeze.
In short, if you’re already familiar with React app architecture, Next.js is the natural upgrade, and moving from React to Next JS solves common headaches while keeping the development process smooth and efficient.

Why One Should Migrate from React to NextJS?
Improved Performance
Next.js enhances load times with server-side rendering (SSR) and static site generation (SSG), delivering pre-rendered HTML to users and boosting performance compared to traditional React apps.
Enhanced SEO Capabilities
By converting your React application to a Next app, you gain significant SEO advantages. Pre-rendered pages are easily indexed by search engines, improving visibility and driving organic traffic. This transition is essential for understanding how to make React SEO-friendly.
Simplified Routing
With file-based routing system, creating new pages is as easy as adding a file. Dynamic routes are also straightforward, allowing you to focus on development without complex configurations.
Seamless Data Fetching
With Next.js, fetching data happens at both build and request times, allowing for a flexible approach to dynamic content and enhancing user interactivity.
Easy Setup and Configuration
The migration process is simple, with sensible defaults that reduce setup time. You can quickly launch your application using the npm run dev command. For more tips on optimizing your workflow, check out our article on offshore React development.
Community and Ecosystem
Next.js benefits from a robust community and ecosystem, with ample documentation, tutorials, and plugins available. As you convert your React project to Next.js, you’ll stay updated on the latest features and best practices.
Scalability
Next.js supports application growth with automatic code splitting and optimized build times, ensuring speed and user experience are maintained as your project expands.

Pros and Cons of Next.js
Pros:
- Enhanced Performance: Features like server-side rendering (SSR) and static site generation (SSG) significantly boost performance. These optimizations ensure faster load times and a smoother user experience, making it easier to convert React JS to Next JS effectively.
- File-Based Routing: Next.js simplifies navigation, making page creation straightforward. This intuitive structure enables rapid app development without the complexities of manual route configuration. For a comparison of frameworks, check out our article on React vs Angular.
- Dynamic Routes: Create responsive applications that adapt to varying user needs. This flexibility is invaluable for modern React apps looking to scale.
Cons:
- Learning Curve: While Next.js builds on React, there can be a learning curve, especially for those unfamiliar with webpack or the intricacies of SSR and SSG. Understanding these concepts is essential for a smooth transition when you migrate from React to Next JS. If you need additional support during this process, consider hiring JS developers for hire who can guide you through the nuances.
- Limited Flexibility: Next.js enforces a certain structure, which can limit flexibility for projects that require a more customized setup. However, this can also be a pro, as it enforces best practices for building scalable applications.
- Configuring Build Settings: In Next.js, it can be a bit tricky for newcomers. It’s important to get familiar with the configuration options in your Next app to steer clear of any potential hiccups during development.
Challenges of Moving from React to Next.js
Understanding SSR and SSG
Unlike traditional React apps that mainly rely on client-side rendering, Next.js lets you select the best rendering method for each page. While this flexibility boosts performance, it also demands a solid grasp of data fetching and server rendering. Investing time to understand these concepts will enhance your app’s speed and SEO in the long run.
Adapting to the File System Routing
Next.js’s file-based routing system can be a change if you’re accustomed to manually setting routes in React. While this approach simplifies navigation, it may initially feel limiting. However, you’ll later find creating new pages and managing dynamic routes becomes much more intuitive, eliminating the need for complicated routing logic.
Dependency on Next.js Ecosystem
Moving to Next.js often means becoming more reliant on its ecosystem and conventions. This can be challenging for developers accustomed to the flexibility of React. For instance, when you convert React to Next.js, you may find that not all existing third-party libraries or plugins are optimized for the Next.js environment.
Performance Monitoring
While Next.js provides numerous optimizations, tracking how these changes impact your application is the cherry on top. You may need to fine-tune your build settings and adjust your data-fetching strategies for optimal results. Leveraging tools like Vercel Analytics allows you to keep tabs on your app’s performance after migration, ensuring it meets user expectations.
Steps to Migrate from React to Next.js
1. Assess Your Current Setup
Before you migrate from React to Next, take a good look at your existing React application. Identify the core features and functionalities that need to be retained. This will help you understand the scope of the migration and how to best structure your React components in the Next.js framework.
2. Create a New Next.js Project
The first hands-on step is to create a new application. You can do this easily with the command: npx create-next-app your-next-app
This command sets up a new Next.js project with all the necessary files and dependencies.
3. Reorganize Your File Structure
With a file-based routing system, your updated project structure will differ from a standard React setup. Move your existing React components into the pages directory as needed. Each file will correspond to a route in your app.
4. Transfer State Management and API Calls
If your React app uses state management libraries like Redux or Context API, transfer this logic into your new project. Ensure that API calls are appropriately handled, particularly if you’re leveraging Next.js’s data-fetching methods.
5. Optimize Build Settings and Configure the Publish Directory
Now it’s time to configure your build settings. Ensure that your Next.js application is optimized for production by adjusting your publish directory settings. This step ensures that your app runs smoothly and efficiently when deployed.
6. Test Your Application Thoroughly
Use tools like Vercel Analytics to monitor performance and identify any issues that may arise during the transition. This step is key to guarantee that everything flows effortlessly post-migration from React to the new ecosystem.
7. Deploy Your Next.js App
Finally, launch your shiny new app! With platforms like Vercel, you can effortlessly take it online and enjoy perks like automatic scaling and built-in CDN support.
