- Developing complex, data-driven interfaces
- Creating reusable component libraries
- When you need maximum flexibility in your tech stack
- For projects that don't require server-side rendering
When to Choose Next.js
- Building e-commerce platforms
- Developing content-heavy websites or blogs
- Creating applications that require excellent SEO
- Building full-stack JavaScript applications
- When you need server-side rendering or static site generation
- For projects that benefit from a more opinionated framework
Code Examples
Let's dive into some code examples to illustrate the capabilities of both React and Next.js.
React Example: Dynamic To-Do List
import React, { useState } from 'react';
const TodoList = () => {
const [todos, setTodos] = useState([]);
const [input, setInput] = useState('');
const addTodo = () => {
if (input) {
setTodos([...todos, input]);
setInput('');
}
};
return (
<div>
<h1>My Todo List</h1>
<input
value={input}
onChange={(e) => setInput(e.target.value)}
placeholder="Add a new todo"
/>
<button onClick={addTodo}>Add</button>
<ul>
{todos.map((todo, index) => (
<li key={index}>{todo}</li>
))}
</ul>
</div>
);
};
export default TodoList;
React Example: Custom Hook for API Fetching
import { useState, useEffect } from 'react';
function useFetch(url) {
const [data, setData] = useState(null);
const [loading, setLoading] = useState(true);
const [error, setError] = useState(null);
useEffect(() => {
async function fetchData() {
try {
const response = await fetch(url);
const json = await response.json();
setData(json);
setLoading(false);
} catch (error) {
setError(error);
setLoading(false);
}
}
fetchData();
}, [url]);
return { data, loading, error };
}
// Usage
function UserProfile({ userId }) {
const { data, loading, error } = useFetch(https://api.example.com/users/</span><span class="p">${</span><span class="nx">userId</span><span class="p">}</span><span class="s2">);
if (loading) return <div>Loading...</div>;
if (error) return <div>Error: {error.message}</div>;
if (!data) return null;
return (
<div>
<h1>{data.name}</h1>
<p>Email: {data.email}</p>
</div>
);
}
Next.js Example: Dynamic Routes with App Router
// app/posts/[id]/page.js
import React from 'react';
async function getPost(id) {
const res = await fetch(https://api.example.com/posts/</span><span class="p">${</span><span class="nx">id</span><span class="p">}</span><span class="s2">);
if (!res.ok) return undefined;
return res.json();
}
export async function generateStaticParams() {
const posts = await fetch('https://api.example.com/posts').then(res => res.json());
return posts.map(post => ({
id: post.id.toString(),
}));
}
export default async function BlogPost({ params }) {
const post = await getPost(params.id);
if (!post) {
return <div>Post not found</div>;
}
return (
<div>
<h1>{post.title}</h1>
<p>{post.content}</p>
</div>
);
}
Next.js Example: API Routes with App Router
// app/api/posts/[id]/route.js
import { NextResponse } from 'next/server';
export async function GET(request, { params }) {
const post = await fetchPostById(params.id);
return NextResponse.json(post);
}
export async function PUT(request, { params }) {
const body = await request.json();
const updatedPost = await updatePost(params.id, body);
return NextResponse.json(updatedPost);
}
export async function DELETE(request, { params }) {
await deletePost(params.id);
return new NextResponse(null, { status: 204 });
}
The Future of React and Next.js
As we look ahead in 2024, both React and Next.js continue to evolve:
- React Server Components: Introduced in React 18, they allow components to run on the server, reducing bundle size and improving performance.

somehow they go to take some likes lol
Most articles on Medium and even here are not make much sense anymore.
Thought I was reading ChatGPT not Dev.to
Next.js is a good option than others
Yes*ok*

App router in Next.js changed everything (something usually does, annually) - been delightful ditching all the state management and pulling straight from server context.
I built a simple 4 page static site (HTML, TailWind, and JS (I have a couple of lists I made from arrays instead of hard coding for easier manageability and a thank you page after the form is submitted that redirects you to the homepage after a certain time lapse.). I was thinking of redoing it in REact so I can have a nav and footer made from a component. Any thoughts?
go straight to next.js safe your time.
ok. still nextjs,
What about when you bring in Sveltekit and compare that too?
I like remix for me it was way easier than learning nextjs
And what is your personal choice?
Thanks! Very useful. A simple compare table is great for comparison.
