Moreover, the ongoing debate about which framework is better Next.js or React has been around for a while. In short, to understand Next.js vs. React, Next.js is a simplified development environment built on top of React.
Which one is perfect for your next web development project, Next.js or React? Let’s explore…
Next.js has built-in support for server-side rendering (SSR) and static site generation (SSG), which help to generate the HTML code for the pages on the server before sending it to the browser. That contributes to both performance optimization and search engine visibility (SEO).
It also offers smooth routing through a file-based system, allowing us to create routes simply by adding files to specific directories.
In Summary, Next.js has many powerful features that help in enhancing the development process like server-side rendering, routing, and performance optimizations. It's an ideal choice for projects that need performance, SEO, and seamless user experiences.
React allows developers to break down the user interface into smaller, reusable components. That makes it easier to manage, and maintain complex projects and build responsive user interfaces for the products.
It uses Virtual DOM behind the scenes to speed up the updates to the webpage. Instead of updating the whole page, React only changes the necessary parts, making the user experience faster and smoother. It uses frameworks like Redux to extend its functionality like routing and state management patterns.
Before we get into the detailed comparison between React and Next.js, let's begin with a descriptive introduction. To assist this exploration, we'll start by presenting a graphical overview of the Next.js vs. React comparison through an informative infographic.

In today's world, Authentication is an important part of web applications as it ensures that only authorized people can access specific resources or perform specific actions. It helps us to protect our sensitive data and maintain user privacy.Just like how your password makes sure your online accounts are only yours.In this guide, we'll discover a simple and safe process for managing authentication in Next.js applications. we’ll set up client-side authentication that doesn’t require a password by using a robust and secure library Auth.js.It will allow users to log in using their social media accounts like Facebook, GitHub, Google, Twitter(X) and so on. Once they've successfully signed up, we'll display their profile picture and email, information we'll pull from their social media accounts.So, let's dive into a step-by-step guide to adding authentication to your Next.js project using Auth.js (NextAuth.js is becoming Auth.js !).Hello, learners! Before we start our authentication journey, let's ensure you're all set:Curiosity: Check!Next.js Basics: If you've worked around with Next.js a bit, you're good.React: A basic understanding of React.js Node.js and npm/yarn: Install Node.js and pick npm or yarn.Code Editor: Any editor you like.Command Line: Basic command-line skills.Feeling confident? Let's start! 🚀Auth.js is an open-source package that is built for authentication in the Next.js application. It is being gradually developed to provide authentication solutions in any framework or library on the web. You can read more about it in detail on the Authjs website.It is a completely secured and flexible authentication library designed to integrate with any OAuth service( like Google, GitHub, Facebook, and more), with full support for passwordless sign-in.With Auth.js, you can implement authentication without dealing with complex authentication protocols and API providers. It's a great tool that makes authentication easier and boosts the security of Next.js projects.Easy: Built-in support for popular services like Google and Facebook, provides email/passwordless/magic link authentication, allows usage with various username/password stores, and is compatible with OAuth services.Flexible: Designed for serverless architecture, adaptability to different environments, compatibility with multiple database options, and offering the choice between database sessions or JWT for authentication.Secure: Features like utilizing signed, prefixed, server-only cookies, incorporating HTTP POST + CSRF Token validation, and supporting JWT with JWS/JWE/JWK for advanced security.To get started, you can either create a new Next.js project or use an existing one. Here's a step-by-step guide to help you get started:Installation: Create a folder named next-auth-app or any other name you want.Open your command line and navigate to your Next.js project's directory. Then, run the below command:You will get a series of questions prompted on your terminal, Select the same options as shown in the screenshot below:In the project named question, we have put . (dot) as we are already in the project directory.Now, launch the development server by using the command below:By default, the project will run on port 3000. Open your browser and visit to http://localhost:3000. You should see the page displayed as:Now that we've successfully set up the Next.js starter application, it's time to get into the process of adding authentication for our Next.js project using Auth.js.This section on configuring authentication with Auth.js will go through the following steps:Installing NextAuth.jsSetting up a GitHub OAuth appCreating a Google OAuth appLet's begin by installing Auth.js. Since it's available as an npm package, the installation process is straightforward.Installing Auth.jsOpen your command line and navigate to your Next.js project's directory. Then, run the command below:Once the installation is complete, you're ready to dive in and configure Auth.js for your project.In our demonstration, we'll provide users with the option to sign in to our application either using their GitHub or Google accounts.Next, our next step involves adding a GitHub Authentication Provider, allowing users to access our application through their GitHub accounts. However, before we proceed, we must create a GitHub OAuth app.Creating a GitHub OAuth app involves several steps. Here's a step to proceed:Navigate to Developer SettingsLog in to your GitHub account.Click on your profile picture in the top right corner.From the dropdown, select "Settings."On the left sidebar, scroll down and select "Developer settings."Or You can directly visit the GitHub OAuth Apps page. Now you will get a webpage as shown below:or Now, Click the "Register New Application" if you are first time here or you will get the "New OAuth App" button if you already have another GitHub OAuth app.OAuth App ConfigurationFill out the following details for your GitHub OAuth app: Application name: Give your app a name.Homepage URL: The URL to your app's homepage. Since we're currently in development mode, we'll need to input the complete URL of our development server. In this case, the URL is http://localhost:3000.Application description: A brief description of your app and its purpose.Authorization callback URL: The URL where GitHub should redirect users after they authorize your app. Click the "Register application" button to generate your OAuth app.After registration, GitHub generates a unique Client ID and Client Secret specifically for our newly created application. Please copy both the Client ID and Client Secret key to your clipboard. If needed, you can click on "Generate new client secret" to obtain a new Client Secret.Now, we have successfully created a Github OAuth application and got the Github Client ID and secrets for our further process.In order to proceed with setting up Auth.js authentication within the Next.js application, you'll need to configure environment variables.Here's how you can create a .env file in a Next.js project and include the GitHub OAuth app credentials, NextAuth SecretsIn your Next.js project's root directory, create a new file and name it .env.Add GitHub OAuth Credentials to .envOpen the .env file in a text editor.Add your GitHub OAuth app credentials as environment variables like this:GITHUB_CLIENT_ID=your_client_id GITHUB_CLIENT_SECRET=your_client_secretReplace your_client_id and your_client_secret with the actual values you obtained when you created the GitHub OAuth app.Now, Generate the NEXTAUTH_SECRET variable, using the command :It will generate a random key for your Next.js applicationNote: In case, you don’t provide a NEXTAUTH_SECRET variable, NextAuth.js will automatically generate a new key on every server start. That will make all your signed tokens and sessions invalid every time your server restarts. It is strongly recommended to provide your own NEXTAUTH_SECRET variable for consistent sessions.Our .env contains these lines of code, copy and paste them:Replace <GITHUB_CLIENT_ID>, <GITHUB_CLIENT_SECRET>, and <NEXTAUTH_SECRET_KEY> with your GitHub client, secret key, and your NextAuth secret.Remember, keep your .env file safe and never commit it to a public repository since it contains sensitive information like your GitHub OAuth app credentials.Now, get back to our App and Create an api/auth/[…nextauth]/route.js file in the app directory and add the following code in the route.js file:In the above code snippet, we import the GitHubProvider from "next-auth/providers/github" It creates a handler responsible for handling authentication requests.The GitHub client ID and secret are fetched from the environment variables GITHUB_CLIENT_ID and GITHUB_CLIENT_SECRET. Finally, we export this handler with the GET and POST, signifying that it will handle both types of HTTP requests for authentication routes.Then, navigate to http://localhost:3000/api/auth/signin and you should see this:Similarly, we can add Google Outh after generating CLIENT_ID and CLIENT_SECERT_ID and adding it to the .env file. Follow the docs to generate Google OAuth credentials.The routes file code will look like this: We have successfully, added authentication to the Next.js project using Auth.js with Github provider and Google provider.In this guide, we successfully added user authentication in the Next.js project using the Auth.js library. NextAuth.js is a secured library to identify our users, get user profile information, and render them in our front end.Implementing authentication can be difficult but Auth.js made it easy. This tutorial was aimed to guide how to implement authentication using NextAuth in the Next.js application. And we covered most of the use cases and implemented the Authentication using OAuth providers like Github and Google but there is a lot more you can do with Auth.js. Such as adding a database using JSON Web Token, securing pages, and more.Please check out this documentation to enhance your learning.Read More
Welcome to the world of Next.js routing! Routing is the backbone of any web application. It's the invisible structure that allows users to navigate seamlessly through different pages and content. It plays a crucial in building user-friendly and dynamic web experiences.Next.js, a popular React framework has always provided developers with a promising solution for achieving both performance and user-friendliness.In 2023, Next.js introduced a new App Router, which takes routing to the next level. It simplifies and enhances the way you handle navigation in your web applications. It comes with features like shared layouts, nested routing, loading states, error handling, and more.In this tutorial, we'll get into the fundamental concepts of routing for the web and how to handle routing, explaining what it is, how it works, and why you should care.Let’s get started…Routing is all about deciding how an application should react when a user asks for a specific URL. When someone clicks a link or enters a URL in their browser, routing figures out which code, usually in the form of a component or handler, should run to create the right response.It is a fundamental concept in web development that enables users to navigate through different pages or views of a web application.In a website, different URLs often correspond to different content or functionality.For example, a URL such as https://example.com/products generally show a page with a list of products, while https://example.com/about lead to an "About Us" page.Routing ensures that accurate content is displayed for each URL.In this section, let's get familiar with some fundamental terminology:Route: It is a defined path or URL pattern that corresponds to a specific page within a web application. Usually, each route has its own unique URL.Route Handler: It is a piece of code responsible for generating the content or response for a specific route. It allows us to create custom request handlers for a given route using the Web Request and Response APIs.Client-Side Routing: In client-side routing, the client (i.e., a web browser) manages the routing completely, avoiding the need to request the entire web page.Server-Side Routing: In server-side routing, the server generates the HTML code for the requested page and then sends it to the Web Browser.Route Parameters: Route parameters allow dynamic values to be part of the URL. For example, in the URL /products/123, "123" could be a route parameter representing a specific product ID.In Next.js, Pages Router and App Router are two essential components that play a crucial role in the user's navigation. In the next section, we will go through a step-by-step guide on using the Page router and App router.The generation and organization of routes a fundamental differences between the Pages Directory and the App Router. Let’s explore this difference:Pages Router: The Next.js project's Pages directory, which is found at the project's root, automatically generates routes based on the folder and file structures included therein. A separate route is associated with each file in the pages directory. For example, the pages directory has a file named about.js that generates a route that is accessible at /about.App Router: On the other hand, App Router arranges routes inside the app folder. It was included in Next.js version 13 and got stable and recommended from the latest release of version 13.4. It provides for more precise control over route organization and introduces concepts like shared layouts, nested routing, and error handling.The decision between these two highly effective routing techniques will depend on the needs of your project and your understanding of the routing concept. However, the App router is recommended.If you decide to use the Pages Router for routing in your Next.js project, follow these steps to set it up:Create a Next.js Application: Use your terminal or code editor to run the following command to start a new Next.js application:Configuration Options: You'll be given a list of configuration options during the application setup process as shown below image. Select "No" when prompted “Would you like to use App Router?”. This ensures that the Pages Directory is configured for your project.Folder Structure: Once your application is created, a pages folder will appear at the project's root. This directory will be the starting point for creating your routes.It is simple to create routes using the Pages Directory (i.e. Pages Router). Follow these steps:Create a Folder: Inside the pages directory, create a new folder with the name you want for your route. For example, you can create a folder named `About` to represent an About Us page.Add an index.js File: Create an index.js file inside the newly created folder. This file will contain the content for the route.Content Creation: In the index.js file, build your page's content using React components and JSX. This content will be displayed when users navigate to the /about route.Linking Pages: You may use the Next.js Link component to make it easier to navigate across pages. You can build links using this component. It will help users switch between pages without requiring a page refresh.Users can seamlessly explore your site, and developers will appreciate how easily routes are organized using folders.Here's the result:While the Pages Directory offers an efficient way to structure routes in a Next.js application, it's important to be aware of its limitations:Static Exports: One of the primary limitations of the Pages Directory is static exports. The Pages Directory relies on dynamic routes generated using getStaticProps and getStaticPaths. Not all pages within the directory can be statically exported, depending on their data requirements.Serverless Functions: Next.js allows to creation of API routes within the Pages Directory, It can handle common API functionality, but more complex serverless functions might require additional configuration and alternative file placement.Statically Generated Pages Distribution: Statically generated pages may require additional CDN configuration or "vendoring" to optimize their performance and distribution to visitors.Edge Runtime Configuration: If you're using the Edge Runtime, you may need to configure routes beyond what's possible within the Pages Directory.Internationalization Routing: To implement internationalization routing effectively, you need to configure locales, default locales, and domain-specific locales. These configurations typically reside in the next.config.js file rather than being solely managed within the Pages Directory.Understanding these limitations will help you make informed decisions when choosing between routing in your Next.js projects. Each mechanism has its own strengths and uses cases.A new App Router was introduced in Next.js version 13.0, built on React Server Components. Which supports shared layouts, nested routing, loading states, error handling, and more. The recent release of Next.js 13.4 marked a significant accomplishment: the new App Router is now production-ready.It allows you to organize your project more flexibly and efficiently. Instead of being restricted to just a "pages" folder, you can group your pages and related files within a single "app" folder.In this section, you will learn how to create the Next.js project using the App Router and lots more about App Router.Here's how to set it up if you choose to use the App router for routing in your Next.js project:Create a Next.js Application: Use your terminal or code editor to run the following command to start a new Next.js application:Configuration Options: You'll be given a list of configuration options during the application setup process as shown below image. Select "Yes" when prompted “Would you like to use App Router?”. This ensures that the App Router is configured for your project.App Router: Once your application is created, an app folder will appear at the project's root. This directory will be the starting point for creating your routes.Before we move further into this tutorial, let’s get a quick overview of the App directory…Next.js uses a file and folder structure to create web page routes:Folders Define Routes: Each folder represents a different page or part of your website. The folders can be nested inside each other to create a hierarchy, just like organizing your files on your computer.Files Create Content: Inside these folders, files contain the actual content or user interface (UI) for each page or section.Next.js provides a set of special files to create UI with specific behaviour in nested routes. See special files:Layout: Shared UI for multiple pagesPage: The content and UI for a specific webpageLoading: UI displayed during data loadingNot-Found: UI is shown when a page or route doesn't existError: UI for handling errors and issuesGlobal Error: UI for handling errors across the whole appRoute: A server-side API endpoint for data and actionsTemplate: Specialized layout for certain types of pagesDefault: Fallback UI when multiple routes match a URLSpecial files of a route segment are rendered in a specific hierarchy, Here it is:Component HierarchyTo create a route for the root URL (localhost:3000), you can follow these simple steps:Inside the app folder, create a page.jsx file if doesn't exist. This file will serve as the home route.In the page.jsx file, create or modify it with a basic React component to represent the "Home" page:By following the above steps, we have successfully created our first route. Now, open your web browser and visit localhost:3000 to see the "This is Home Page!" message.Now, Let's proceed to create two more additional routes: one for the About page and another for the Dashboard page.Create an app/about folder.Inside the about folder, create a page.jsx file. This file represents the route.On the page.jsx file, define a basic component to represent the "About Us" page:Similarly, create an app/dashboard folder.Inside the dashboard folder, create a page.jsx file. This file represents the route.On the page.jsx file, define a basic component to represent the "Dashboard" page:If you visit the root URL, localhost:3000, the home page will be displayed. However, if you visit localhost:3000/about, the "About Us" page will be displayed. Similarly, /dashboard URL will show the "Dashboard" page.This shows how routes are linked to files based on the name of the contained folder inside the app folder. The page.jsx file within the about folder represents /about, while the page.jsx file within the dashboard folder represents /dashboard.To set up nested routes in Next.js, follow these steps:Create an app/blog folder or whatever name you want.Inside the blog folder, create a page.jsx file for the main page of the blog:Visit localhost:3000/blog in the browser to see the "Main Blog" page.To implement /blog/firstPage and /blog/secondPage routes, create page.jsx files in the app/blog/firstPage and app/blog/secondPage folders with the following code:The folder structure will look like this:Now, when you navigate to localhost:3000/blog/firstPage, you'll see the first page of the blog post, and localhost:3000/blog/secondPage will display the second page of the blog post.By organizing the files in a nested folder structure, Next.js automatically handles the routing. This simplifies the process of creating nested routes and improves the overall organization and structure of the application.To set up dynamic routes in Next.js for a product listing and detail page, follow these steps:Create an app/products folder.Inside the products folder, create a page.jsx file to display a list of the products:Visit localhost:3000/products in the browser, The Products list will be displayed on the screen.For the product detail page, create a new folder within the products folder and name it [productId]. The square brackets indicate a dynamic route.Inside the [productId] folder, create a page.jsx file:Now, when you navigate to localhost:3000/products/1, you'll see the product details page. Similarly, accessing /products/2, /products/3, or even /products/100 will display the same details page. [productId] is the dynamic route segment that can adapt values like 1, 2, 3, and so on.To display the specific product ID, use the params object to display on each page. Modify the code as below:Now, when you navigate to localhost:3000/products/1, you'll see "Details about product 1" displayed. Similarly, /products/100 will show details about “Product 100."Dynamic routes help create list-detail patterns in UI apps. By learning how to create dynamic routes in Next.js, you can create flexible and scalable applications that adapt to varying user interactions.In the previous section, we covered dynamic routes, and now, we'll learn about nested dynamic routes.Nested dynamic routes in Next.js allow us to create complex and dynamic URL structures by combining multiple dynamic route segments.For example, when visiting to /products/1, users expect to view details for product 1. Likewise, visiting /products/1/reviews/1 should show the first review of that product.We'll explore how to achieve this using the App Router.To create nested dynamic routes in Next.js, follow these steps:Create an app/products/[productId]/reviews folder. This structure leads to the route "/products/productId/reviews." We also need a dynamic reviewId to show specific reviews.Within the reviews folder, create a new folder named [reviewId]. Once again, the square brackets indicate a dynamic route.Inside the [reviewId] folder, create a page.jsx file, here we'll create a component to display both the productId and the reviewId of the product:Now, by navigating to localhost:3000/products/1/reviews/1 in the browser, you'll see the expected content is displayed. Similarly, exploring other product IDs and review IDs will dynamically show the relevant values in the user interface.Next.js will automatically respond with an Error: 404 Not Found response when you provide a URL that is not available within the app folder, such as /profile. Since Next.js takes care of this for you, you don't need to manually handle non-matching routes.The App Router in Next.js offers advanced features that go beyond what we've discussed so far. It includes features such as File colocation, Private folders, Route groups, server actions, data revalidation, parallel routes, and route interception, which add more functionality to your application.For a better understanding and mastery of these features, you can refer to the official Next.js documentation, which provides comprehensive information on these features in Next.js.In summary, routing is an essential part of web development. It enables users to navigate seamlessly across websites, providing the structure and pathways needed to access different pages and content.In this tutorial, we explored the basics of routing in Next.js 13 and learned how to structure routes using both the Pages Router and the App Router. We specifically focused on the stable App router introduced in the latest version Next.js 13.4.We discussed routing terminology, learned about specific files, created routes for different aspects, and also discussed about key differences between the App router and the Page Router.By exploring these concepts, you've not only understood what these tools can do but also got an idea about when to use the App Router and when to stick with the old way of using the Pages Directory.Stay tuned for more exciting tutorials!Read More
