Create React App, provided by Facebook, is a reliable workhorse known for its simplicity, making it ideal for beginners and straightforward projects. On the other hand, NextJs is a fresh-faced newcomer packed with exciting features like built-in server-side rendering (SSR) and static site generation (SSG), offering a performance boost and SEO-friendly capabilities right off the bat.

Taking&#8217; a peek at your current setup \u2013 files, folders, and dependencies<\/h3>\n\n\n\n<p>Let&#8217;s get a good look at your current website setup. Round up the files, folders, and dependencies \u2013 it&#8217;s time for a thorough inspection. Take stock of your project&#8217;s directory structure, check for any custom configurations, and all the dependencies you&#8217;ve been using. Knowing what you&#8217;ve got will help us plan the best route for the migration.<\/p>\n\n\n\n<p>Here is an example of what this may look like&#8230;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-style-default\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"631\" src=\"https:\/\/www.vocso.com\/blog\/wp-content\/uploads\/2023\/07\/directory-structure-1024x631.png\" alt=\"directory structure\" class=\"wp-image-30836\" srcset=\"https:\/\/www.vocso.com\/blog\/wp-content\/uploads\/2023\/07\/directory-structure-1024x631.png 1024w, https:\/\/www.vocso.com\/blog\/wp-content\/uploads\/2023\/07\/directory-structure-300x185.png 300w, https:\/\/www.vocso.com\/blog\/wp-content\/uploads\/2023\/07\/directory-structure-768x474.png 768w, https:\/\/www.vocso.com\/blog\/wp-content\/uploads\/2023\/07\/directory-structure-624x385.png 624w, https:\/\/www.vocso.com\/blog\/wp-content\/uploads\/2023\/07\/directory-structure.png 1197w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">B. Spotting any hurdles ahead for the migration<\/h3>\n\n\n\n<p>Every trail has got its rough patches, and the migration trail isn\u2019t any different. Let&#8217;s put on our cowboy hats and keep an eye out for any hurdles that might be waiting up ahead. Look for any React-specific features or third-party libraries that might need special attention during the migration. We&#8217;ll rope &#8217;em in one by one and find the best way to handle them.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code lang=\"jsx\" class=\"language-jsx line-numbers\">import React from 'react';\nimport { BrowserRouter as Router, Switch, Route, Link } from 'react-router-dom';\n\nfunction App() {\n  return (\n    &lt;Router&gt;\n      &lt;nav&gt;\n        &lt;ul&gt;\n          &lt;li&gt;\n            &lt;Link to=\"\/\"&gt;Home&lt;\/Link&gt;\n          &lt;\/li&gt;\n          &lt;li&gt;\n            &lt;Link to=\"\/about\"&gt;About&lt;\/Link&gt;\n          &lt;\/li&gt;\n        &lt;\/ul&gt;\n      &lt;\/nav&gt;\n\n      &lt;Switch&gt;\n        &lt;Route exact path=\"\/\"&gt;\n          &lt;Home \/&gt;\n        &lt;\/Route&gt;\n        &lt;Route path=\"\/about\"&gt;\n          &lt;About \/&gt;\n        &lt;\/Route&gt;\n      &lt;\/Switch&gt;\n    &lt;\/Router&gt;\n  );\n}\n<\/code><\/pre>\n\n\n\n<p>Now, let&#8217;s be on the lookout for any pesky hurdles on the trail. Say you&#8217;ve been using a third-party library like react-router-dom for navigation:<\/p>\n\n\n\n<p>No need to fret! NextJs has got its own built-in routing system, so we&#8217;ll guide you on how to adjust your navigation for the smoothest ride.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">C. Getting your website ready to ride into the NextJs frontier<\/h3>\n\n\n\n<p>Now that we&#8217;ve assessed the situation, it&#8217;s time to get your website ready for the NextJs adventure. Let&#8217;s say you&#8217;ve got a simple React component like this:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code lang=\"jsx\" class=\"language-jsx line-numbers\">import React from 'react';\n\nfunction Greeting({ name }) {\n  return &lt;h1&gt;Hello, {name}!&lt;\/h1&gt;;\n}\n\nexport default Greeting;<\/code><\/pre>\n\n\n\n<p><strong><em>We&#8217;ll help you convert it into a NextJs-friendly page like this:<\/em><\/strong><\/p>\n\n\n\n<pre class=\"wp-block-code\"><code lang=\"jsx\" class=\"language-jsx line-numbers\">import React from 'react';\n\nfunction Greeting({ name }) {\n  return &lt;h1&gt;Hello, {name}!&lt;\/h1&gt;;\n}\n\nexport default Greeting;\n\nexport async function getServerSideProps() {\n  \/\/ Fetch data or perform actions before rendering the page\n  return {\n    props: {\n      name: 'John', \/\/ Set a default name for now\n    },\n  };\n}<\/code><\/pre>\n\n\n\n<p><em>We&#8217;ll walk you through every step, so you&#8217;re all set for the ride into the NextJs frontier!<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"getting-started-with-nextjs\"><\/span>Getting Started with NextJs<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">A. Using NextJs and the tools you need<\/h3>\n\n\n\n<p>First off, make sure you&#8217;ve got <a href=\"https:\/\/www.vocso.com\/blog\/migrating-to-next-js-from-reactjs\/\" target=\"_blank\" rel=\"noreferrer noopener\">Node JS<\/a> installed on your system \u2013 we&#8217;ll need it to run NextJs. Once you&#8217;ve got Node JS, you can easily use Next.js by using the following command in your terminal or command prompt:<\/p>\n\n\n\n<p><em>npx create-next-app my-next-project<\/em><\/p>\n\n\n\n<p>This will create a brand new NextJs project named &#8220;my-next-project&#8221; in your current directory. Yes sir, it&#8217;s as easy as that!<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">B. Starting fresh with a brand new NextJs project<\/h3>\n\n\n\n<p>Now that you&#8217;ve got your NextJs project all setup, it&#8217;s time to climb on that horse and start fresh! Head on over to your project directory and start the development server with this command:<\/p>\n\n\n\n<p><em>cd my-next-project<\/em><\/p>\n\n\n\n<p><em>npm run dev<\/em><\/p>\n\n\n\n<p>This will fire up the development server, and you can preview your brand-spankin&#8217;-new NextJs application by visiting&#8217; http:\/\/localhost:3000 in your browser.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">C. Getting&#8217; to know the lay of the land \u2013 the NextJs project structure<\/h3>\n\n\n\n<p>Let&#8217;s take a look at your new NextJs project. Here&#8217;s a look at the project structure:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-style-default\"><img loading=\"lazy\" decoding=\"async\" width=\"957\" height=\"716\" src=\"https:\/\/www.vocso.com\/blog\/wp-content\/uploads\/2023\/07\/new-nextjs-projec-structure.png\" alt=\"new nextjs projec structure\" class=\"wp-image-30841\" srcset=\"https:\/\/www.vocso.com\/blog\/wp-content\/uploads\/2023\/07\/new-nextjs-projec-structure.png 957w, https:\/\/www.vocso.com\/blog\/wp-content\/uploads\/2023\/07\/new-nextjs-projec-structure-300x224.png 300w, https:\/\/www.vocso.com\/blog\/wp-content\/uploads\/2023\/07\/new-nextjs-projec-structure-768x575.png 768w, https:\/\/www.vocso.com\/blog\/wp-content\/uploads\/2023\/07\/new-nextjs-projec-structure-624x467.png 624w\" sizes=\"auto, (max-width: 957px) 100vw, 957px\" \/><\/figure>\n\n\n\n<p>In NextJs, the pages directory is where the magic happens! Each file in the pages directory represents a route in your application. For example, index.js represents the home page, and you can create other files like about.js for the about page. Don&#8217;t forget about the public directory, where you can store your static assets like images or favicons.<\/p>\n\n\n\n<p>There you have it, buckaroo! You&#8217;ve saddled up your NextJs project, and now you&#8217;re ready to ride into the wild west of web development. Happy trailblazing!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"rounding-up-components-and-assets-%e2%80%93-migrating-your-website\"><\/span>Rounding Up Components and Assets &#8211; Migrating Your Website<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">A. Mapping out your current React components to NextJs pages<\/h3>\n\n\n\n<p><strong>Say you&#8217;ve got a React component like this in your previous project:<\/strong><\/p>\n\n\n\n<pre class=\"wp-block-code\"><code lang=\"jsx\" class=\"language-jsx line-numbers\">\/\/ Previous Project: components\/Header.js\nimport React from 'react';\n\nfunction Header() {\n  return &lt;header&gt;Howdy, partner! Welcome to the website!&lt;\/header&gt;;\n}\n\nexport default Header;<\/code><\/pre>\n\n\n\n<p><strong>To migrate it to NextJs, create a new file named Header.js inside the pages directory, like so:<\/strong><\/p>\n\n\n\n<pre class=\"wp-block-code\"><code lang=\"jsx\" class=\"language-jsx line-numbers\">\/\/ Next.js Project: pages\/Header.js\nimport React from 'react';\n\nfunction Header() {\n  return &lt;header&gt;Howdy, partner! Welcome to the website!&lt;\/header&gt;;\n}\n\nexport default Header;\n\n<\/code><\/pre>\n\n\n\n<p>This is exactly the same, except NextJs will automatically treat this as a new page with the route \/header. Just like that, we&#8217;ve mapped our React component to a Next.js page!<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">B. Sorting out the styles \u2013 global and modular \u2013 in NextJs<\/h3>\n\n\n\n<p>For global styles, create a globals.css file inside the styles directory. NextJs will handle it automatically without any extra effort.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code lang=\"css\" class=\"language-css line-numbers\">\/* Next.js Project: styles\/globals.css *\/\nbody {\n  font-family: 'Roboto', sans-serif;\n  margin: 0;\n  padding: 0;\n}<\/code><\/pre>\n\n\n\n<p><strong>Now, for modular styles, let&#8217;s say you have a component with its CSS like this:<\/strong><\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Previous Project: components\/Button.js\nimport React from 'react';\nimport '.\/Button.css';\n\nfunction Button({ label }) {\n  return &lt;button className=\"custom-button\"&gt;{label}&lt;\/button&gt;;\n}\n\nexport default Button;<\/code><\/pre>\n\n\n\n<p><strong>Move the Button.css file into the same directory as the component, and NextJs will handle the import for you:<\/strong><\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Next.js Project: components\/Button.js\nimport React from 'react';\n\nfunction Button({ label }) {\n  return &lt;button className=\"custom-button\"&gt;{label}&lt;\/button&gt;;\n}\n\nexport default Button;\n<\/code><\/pre>\n\n\n\n<p>Next.js will ensure that your styles are applied correctly to the components, just like you&#8217;re used to.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">C. Keepin&#8217; your static assets and resources safe during the move<\/h3>\n\n\n\n<p>Your static assets, like images, can find a new home in the public directory. For example, move your logo.png into the public directory like this:<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/lh5.googleusercontent.com\/aKgq1Jser2psmlcIcqq971ztdhZX6vZrFfGQFtB2YDkJjjnuPW_yYgevWDsOgwMGgqSBAgJbhblj17V1ZI0fpeEnWj5uM-jzWvNoDNCUOODkTKvLT3QjdGir_DUJ5jvWkKKMvMGZVUalxg4VmNXcz7o\" alt=\"\"\/><\/figure>\n\n\n\n<p><strong>Now, you can reference your image like this in your components:<\/strong><\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Next.js Project: components\/Logo.js\nimport React from 'react';\n\nfunction Logo() {\n  return &lt;img src=\"\/logo.png\" alt=\"Logo\" \/&gt;;\n}\n\nexport default Logo;<\/code><\/pre>\n\n\n\n<p>NextJs will take care of serving the image from the public directory.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"managing-routing-and-navigation\"><\/span>Managing Routing and Navigation<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">A. Navigating&#8217; the differences between ReactJS and NextJS routing<\/h3>\n\n\n\n<p>In ReactJS, you might have used react-router-dom like this for client-side routing:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Previous Project: routes\/AppRouter.js\nimport React from 'react';\nimport { BrowserRouter as Router, Switch, Route } from 'react-router-dom';\nimport Home from '..\/components\/Home';\nimport About from '..\/components\/About';\nimport NotFound from '..\/components\/NotFound';\n\nfunction AppRouter() {\n  return (\n    &lt;Router&gt;\n      &lt;Switch&gt;\n        &lt;Route exact path=\"\/\"&gt;\n          &lt;Home \/&gt;\n        &lt;\/Route&gt;\n        &lt;Route path=\"\/about\"&gt;\n          &lt;About \/&gt;\n        &lt;\/Route&gt;\n        &lt;Route path=\"*\"&gt;\n          &lt;NotFound \/&gt;\n        &lt;\/Route&gt;\n      &lt;\/Switch&gt;\n    &lt;\/Router&gt;\n  );\n}\n\nexport default AppRouter;\n<\/code><\/pre>\n\n\n\n<p><strong>In NextJs, you won&#8217;t need the react-router-dom library. Instead, you&#8217;ll use NextJs&#8217;s file-based routing. Create individual files for each page inside the pages directory, like this:<\/strong><\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Next.js Project: pages\/index.js\nimport React from 'react';\n\nfunction Home() {\n  return &lt;div&gt;Howdy, this is the home page!&lt;\/div&gt;;\n}\n\nexport default Home;<\/code><\/pre>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Next.js Project: pages\/about.js\nimport React from 'react';\n\nfunction About() {\n  return &lt;div&gt;This is the about page!&lt;\/div&gt;;\n}\n\nexport default About;<\/code><\/pre>\n\n\n\n<p>NextJs will automatically handle the routing based on these files.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">B. Giving your website some smooth client-side navigation in NextJs<\/h3>\n\n\n\n<p>To create smooth client-side navigation in NextJs, use the Link component from NextJs:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Next.js Project: pages\/index.js\nimport React from 'react';\nimport Link from 'next\/link';\n\nfunction Home() {\n  return (\n    &lt;div&gt;\n      &lt;div&gt;Howdy, this is the home page!&lt;\/div&gt;\n      &lt;Link href=\"\/about\"&gt;\n        &lt;a&gt;About&lt;\/a&gt;\n      &lt;\/Link&gt;\n    &lt;\/div&gt;\n  );\n}\n\nexport default Home;<\/code><\/pre>\n\n\n\n<p>NextJs takes care of the client-side navigation, so you&#8217;ll get that smooth transition between pages.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">C. Handling dynamic routes and the query parameters<\/h3>\n\n\n\n<p>NextJs makes handlin&#8217; dynamic routes and query parameters a breeze. Let&#8217;s say you have a dynamic route like this:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Next.js Project: pages\/posts\/[postId].js\nimport React from 'react';\nimport { useRouter } from 'next\/router';\n\nfunction Post() {\n  const router = useRouter();\n  const { postId } = router.query;\n\n  return &lt;div&gt;This is the post with ID: {postId}&lt;\/div&gt;;\n}\n\nexport default Post;<\/code><\/pre>\n\n\n\n<p>When you visit \/posts\/123, NextJs will automatically fetch the data and render the page with the ID 123.<\/p>\n\n\n\n<p><strong>For query parameters, you can lasso &#8217;em up using the useRouter hook:<\/strong><\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Next.js Project: pages\/search.js\nimport React from 'react';\nimport { useRouter } from 'next\/router';\n\nfunction Search() {\n  const router = useRouter();\n  const { query } = router.query;\n\n  return &lt;div&gt;Search results for: {query}&lt;\/div&gt;;\n}\n\nexport default Search;<\/code><\/pre>\n\n\n\n<p>When you visit \/search?query=cowboys, NextJs will fetch the query parameter and display &#8220;Search results for cowboys.&#8221;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"use-data-like-a-pro-%e2%80%93-data-fetching-and-api-integration\"><\/span>Use Data Like a Pro &#8211; Data Fetching and API Integration<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">A. Fetching data in ReactJS \u2013 what you&#8217;ve been doing so far<\/h3>\n\n\n\n<p>In ReactJS, you might have been fetching data using libraries like axios or the built-in fetch API. You&#8217;d typically do this inside a use effect hook to fetch the data when the component mounts. Here&#8217;s an example of how you might have done it:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Previous Project: components\/PostList.js\nimport React, { useState, useEffect } from 'react';\nimport axios from 'axios';\n\nfunction PostList() {\n  const [posts, setPosts] = useState([]);\n\n  useEffect(() =&gt; {\n    axios.get('https:\/\/api.example.com\/posts')\n      .then(response =&gt; setPosts(response.data))\n      .catch(error =&gt; console.error(error));\n  }, []);\n\n  return (\n    &lt;div&gt;\n      {posts.map(post =&gt; (\n        &lt;div key={post.id}&gt;{post.title}&lt;\/div&gt;\n      ))}\n    &lt;\/div&gt;\n  );\n}\n\nexport default PostList;\n<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">B. Embracing NextJs data fetching methods \u2013 getStaticProps, getServerSideProps, and more<\/h3>\n\n\n\n<p>NextJs offers some powerful data fetching methods, depending on your needs. You got getStaticProps for static site generation (SSG) and getServerSideProps for server-side rendering (SSR). These methods allow you to fetch data at build time or request time, and NextJs takes care of the rest. Here&#8217;s an example of how you might use getStaticProps:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Next.js Project: pages\/posts.js\nimport React from 'react';\n\nfunction Posts({ posts }) {\n  return (\n    &lt;div&gt;\n      {posts.map(post =&gt; (\n        &lt;div key={post.id}&gt;{post.title}&lt;\/div&gt;\n      ))}\n    &lt;\/div&gt;\n  );\n}\n\nexport default Posts;\n\nexport async function getStaticProps() {\n  const response = await fetch('https:\/\/api.example.com\/posts');\n  const posts = await response.json();\n\n  return {\n    props: {\n      posts,\n    },\n  };\n}\n<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">C. Hooking up with APIs<\/h3>\n\n\n\n<p>NextJs makes hooking up with APIs a breeze! Whether it&#8217;s a REST API or a GraphQL endpoint, you can fetch the data right in your NextJs components. Let&#8217;s say you want to fetch data from a REST API:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Next.js Project: pages\/users.js\nimport React from 'react';\n\nfunction Users({ users }) {\n  return (\n    &lt;div&gt;\n      {users.map(user =&gt; (\n        &lt;div key={user.id}&gt;{user.name}&lt;\/div&gt;\n      ))}\n    &lt;\/div&gt;\n  );\n}\n\nexport default Users;\n\nexport async function getStaticProps() {\n  const response = await fetch('https:\/\/api.example.com\/users');\n  const users = await response.json();\n\n  return {\n    props: {\n      users,\n    },\n  };\n}\n<\/code><\/pre>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"keep-your-website-in-line-%e2%80%93-state-management\"><\/span>Keep Your Website in Line &#8211; State Management<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">A. Understanding state management options in NextJs territory<\/h3>\n\n\n\n<p>In the vast territory of NextJs, you have a few options for managing the state in your application. One popular approach is to use React&#8217;s built-in useState hook, just like you&#8217;ve been doing in ReactJS. It&#8217;s a simple and effective way to handle the local component state. But when your application gets larger and more complex, you might need to rope in some additional tools for more advanced state management.<\/p>\n\n\n\n<p>NextJs plays well with other state management libraries like Redux, Zustand, or Mobx. These libraries allow you to centralize your application&#8217;s state and manage it more efficiently, making it easier to work with the data and keep your website in line.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">B. Getting&#8217; them state variables under control<\/h3>\n\n\n\n<p>When using useState in NextJs, it&#8217;s just as straightforward as you&#8217;ve been doin&#8217; in ReactJS. Here&#8217;s an example of how you might use useState to manage a counter:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Next.js Project: pages\/Counter.js\nimport React, { useState } from 'react';\n\nfunction Counter() {\n  const [count, setCount] = useState(0);\n\n  const handleIncrement = () =&gt; {\n    setCount(count + 1);\n  };\n\n  const handleDecrement = () =&gt; {\n    setCount(count - 1);\n  };\n\n  return (\n    &lt;div&gt;\n      &lt;h2&gt;Count: {count}&lt;\/h2&gt;\n      &lt;button onClick={handleIncrement}&gt;Increment&lt;\/button&gt;\n      &lt;button onClick={handleDecrement}&gt;Decrement&lt;\/button&gt;\n    &lt;\/div&gt;\n  );\n}\n\nexport default Counter;\n<\/code><\/pre>\n\n\n\n<p>That&#8217;s how you keep the state variables under control with useState in NextJs!<\/p>\n\n\n\n<p>And if you ever need to do something complex in state management, just consider working with libraries like Redux or Zustand.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"handling-side-effects-and-lifecycle-methods\"><\/span>Handling Side Effects and Lifecycle Methods<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">A. Differences in lifecycle methods between ReactJS and NextJs<\/h3>\n\n\n\n<p>On the dusty trail between ReactJS and NextJs, there are some differences in the way you handle lifecycle methods. In ReactJS, you might have used componentDidMount, componentDidUpdate, and componentWillUnmount in class-based components for managing side effects.&nbsp;<\/p>\n\n\n\n<p>In the realm of NextJs and functional components, the go-to solution for handling side effects and lifecycle events is the use effect hook. Fear not, as this versatile and powerful hook can handle all sorts of side effects and keep your application running smoothly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">B. Adjusting your code with useEffect, componentDidMount, and the likes<\/h3>\n\n\n\n<p>Let&#8217;s say you&#8217;ve been using componentDidMount in ReactJS to fetch data when the component mounts. Now, with NextJs and functional components, you&#8217;ll be using use effect to achieve the same outcome:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Next.js Project: components\/PostList.js\nimport React, { useState, useEffect } from 'react';\nimport axios from 'axios';\n\nfunction PostList() {\n  const [posts, setPosts] = useState([]);\n\n  useEffect(() =&gt; {\n    \/\/ This code will run when the component mounts\n    axios.get('https:\/\/api.example.com\/posts')\n      .then(response =&gt; setPosts(response.data))\n      .catch(error =&gt; console.error(error));\n\n    \/\/ The cleanup function for componentWillUnmount will be returned here (optional)\n    return () =&gt; {\n      \/\/ Any cleanup code you need goes here\n    };\n  }, []);\n\n  \/\/ Render the list of posts\n}\n\nexport default PostList;\n<\/code><\/pre>\n\n\n\n<p>With effect, you can perform data fetching and other side effects when the component mounts, just like componentDidMount in ReactJS. Additionally, you can include cleanup logic in the returned function from useEffect, similar to component will unmount.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"server-side-rendering-ssr-and-static-site-generation-ssg\"><\/span>Server-side Rendering (SSR) and Static Site Generation (SSG)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">A. Getting ready for some server-side rendering and static site generation in NextJs<\/h3>\n\n\n\n<p>NextJs offers two powerful techniques for rendering your pages: Server-side Rendering (SSR) and Static Site Generation (SSG). SSR fetches data and renders the pages on each request, while SSG generates the pages at build time and serves them as static files.&nbsp;<\/p>\n\n\n\n<p>With SSR, you can fetch data from APIs on the server and deliver a fully populated page to your users. On the other hand, SSG pre-renders the pages, providing blazing-fast loading times and better SEO.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">B. Transforming your pages for SSR or SSG \u2013 better performance and SEO gold<\/h3>\n\n\n\n<p>Let&#8217;s see how you can transform your pages to leverage SSR or SSG. For SSR, you can use the getServerSideProps function inside a page file. It&#8217;ll fetch the data on each request and pre-populate the page before sending it to the user. Here&#8217;s an example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Next.js Project: pages\/posts\/[postId].js\nimport React from 'react';\n\nfunction Post({ post }) {\n  return (\n    &lt;div&gt;\n      &lt;h1&gt;{post.title}&lt;\/h1&gt;\n      &lt;p&gt;{post.content}&lt;\/p&gt;\n    &lt;\/div&gt;\n  );\n}\n\nexport default Post;\n\nexport async function getServerSideProps({ params }) {\n  const { postId } = params;\n  const response = await fetch(`https:\/\/api.example.com\/posts\/${postId}`);\n  const post = await response.json();\n\n  return {\n    props: {\n      post,\n    },\n  };\n}\n<\/code><\/pre>\n\n\n\n<p>For SSG, you can use the getStaticProps function to fetch data at build time and pre-render the pages as static files. Here&#8217;s an example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Next.js Project: pages\/posts.js\nimport React from 'react';\n\nfunction Posts({ posts }) {\n  return (\n    &lt;div&gt;\n      {posts.map(post =&gt; (\n        &lt;div key={post.id}&gt;\n          &lt;h2&gt;{post.title}&lt;\/h2&gt;\n          &lt;p&gt;{post.content}&lt;\/p&gt;\n        &lt;\/div&gt;\n      ))}\n    &lt;\/div&gt;\n  );\n}\n\nexport default Posts;\n\nexport async function getStaticProps() {\n  const response = await fetch('https:\/\/api.example.com\/posts');\n  const posts = await response.json();\n\n  return {\n    props: {\n      posts,\n    },\n  };\n}\n<\/code><\/pre>\n\n\n\n<p>With SSR and SSG, your NextJs application will be blazing fast, performant, and SEO-friendly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"testing-and-debugging\"><\/span>Testing and Debugging<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">A. Checking your website with testing frameworks for NextJs<\/h3>\n\n\n\n<p>Testing is essential to keep your NextJs website running smoothly and error-free. There are several testing frameworks you can use to ensure your code is in tip-top shape. One popular choice is Jest, a powerful and easy-to-use testing framework.&nbsp;<\/p>\n\n\n\n<p>Jest allows you to write unit tests, integration tests, and even snapshot tests for your components. With NextJs&#8217;s built-in support for Jest, you can saddle up and start testing&#8217; your website with confidence.<\/p>\n\n\n\n<p>Here&#8217;s an example of a simple unit test using Jest for a NextJs component:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\">\/\/ Next.js Project: components\/Button.js\nimport React from 'react';\n\nfunction Button({ label }) {\n  return &lt;button&gt;{label}&lt;\/button&gt;;\n}\n\nexport default Button;\n\n\/\/ Next.js Project: components\/__tests__\/Button.test.js\nimport React from 'react';\nimport { render, screen } from '@testing-library\/react';\nimport Button from '..\/Button';\n\ntest('renders button with correct label', () =&gt; {\n  render(&lt;Button label=\"Click Me\" \/&gt;);\n  const buttonElement = screen.getByText(\/click me\/i);\n  expect(buttonElement).toBeInTheDocument();\n});\n<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">B. Tracking down and solving bugs<\/h3>\n\n\n\n<p>Bugs can be as tricky as a slippery snake in the desert, but NextJs provides some handy tools to track &#8217;em down and solve &#8217;em. One of the most powerful tools is the browser&#8217;s built-in developer tools. Use the console and inspect elements to spot any errors or unexpected behavior.&nbsp;<\/p>\n\n\n\n<p>Additionally, NextJs comes with a development mode that provides detailed error messages and stack traces to help you fix these bugs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"deployment-considerations\"><\/span>Deployment Considerations<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">A. Getting your website ready \u2013 production build in NextJs<\/h3>\n\n\n\n<p>Use <strong>npm run build <\/strong>or <strong>yarn build<\/strong> to create an optimized production build of your NextJs website.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">B. Choosing the best places to host your site and go live<\/h3>\n\n\n\n<p>Consider hosting providers like Vercel, Netlify, or AWS Amplify for seamless integration with NextJs. Deploy your website with ease and enjoy automatic deployments, scalability, and excellent performance.<\/p>\n\n\n\n<p>For example, if you choose Vercel, deploying your NextJs website is as easy as a quick ride:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Install Vercel CLI with `<strong>npm install -g vercel`<\/strong><\/li><li>Use `<strong>vercel login`<\/strong> to log in to your Vercel account<\/li><li>Navigate to your NextJs project directory and run `vercel`<\/li><li>Follow the prompts to deploy your website to Vercel<\/li><\/ul>\n\n\n\n<p>Once deployed, your website will be live for the world to see at the provided URL. Time to celebrate, partner \u2013 your NextJs website is officially on the world wide web!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"wrapping-up-%e2%80%93-after-the-move-tasks-and-clean-up\"><\/span>Wrapping Up &#8211; After the Move Tasks and Clean-up<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">A. Reviewing your migrated website for any fixes<\/h3>\n\n\n\n<p>After migrating to NextJs, take a look at your website and ensure everything is working smoothly. Check for any broken links, missing content, or layout issues.&nbsp;<\/p>\n\n\n\n<p>For example, verify that all pages load correctly and that forms and buttons function as expected.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">B. Clearing out unused code and dependencies like dust in the wind<\/h3>\n\n\n\n<p>Clean up your codebase by removing any unused code or dependencies. It&#8217;s like sweeping away dust in the wind to keep your project tidy and efficient.&nbsp;<\/p>\n\n\n\n<p>For instance, if you previously used a library that is no longer needed in NextJs, remove it from your project to reduce unnecessary bloat.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">C.
