Before we dive into the actual developer experience, it helps to have some background. I personally prefer not to home-roll when there is a viable meta framework available like Next.js, but that choice is based more on developer ergonomics rather than performance. I got 80% improvement on FMP, FCP which also improve the lead conversion by 15%. These diagrams postulate that SSR can deliver HTML to the browser faster than CSR can, so let’s make that our hypothesis: a web application built with SSR is more performant than one built with CSR. November 5, 2020 It also records the HTML and CSS on the page, recreating pixel-perfect videos of even the most complex single-page apps. Whether you decide on Next.js, Create React App, or another framework, monitoring performance is key. The added advantage of pulling in data with Next.js is just that the resulting bundle is prerendered which makes it easier for consumers of your site. Going beyond the simple “hello world” project, it was fairly easy to find help, whether it be in the documentation or community resources. If React is ever to win said dispute, it will need a solid framework to do so. LogRocket is like a DVR for web apps, recording literally everything that happens on your React app. The react folder in the project is the React version, of course, and the next.js folder contains the Next.js version. It mirrors the file paths to your pages and even allows for … The ThemeProvider, PrimaryNav, etc. Software developers are typically spoiled with high-powered computers paired with blazingly fast office networks; we do not always experience our applications the same way our users do. In both React and Next.js, the active community provides for a very positive developer experience. As I mentioned in the intro, Next.js has a “learn-by-doing” set of documentation that walks you through how to do things like routing and building components. This post is not going to be about the differences in how to use React vs. Preact.Quite simply, with Preact's compatibility package, there are nearly zero differences in how to write code. This then can then be deployed with my site, enabling an RSS feed. LogRocket logs all actions and state from your Redux stores. With any software project, good documentation can really help you to easily use tools, understand what libraries to use, etc. Our work with Next.js comes out much faster than if it was built on pure React or frameworks alike. Make performance a priority – Start monitoring for free. In the last episodes, I took a look at JavaScript vs TypeScript and React vs Vue vs Angular vs Svelte. Create React App (CRA) Next.js. At the end of the day, both React and Next.js provide solid developer experiences. Additionally, it was easy to navigate when I wanted to add components to my site for the different pages. There is a small learning curve with Next.js, but even developers new to the world of frontend can get up and running relatively quickly. Likewise, Create React App is one way that you can leverage React to support client-side rendering (CSR). Next.js is written in TypeScript and as such comes with an excellent TypeScript support. There are fantastic documentation options available for both React and Next.js. Look at what that means for data fetching between these two applications. I have experience with CRA but am considering Next.js for a new project. The Header component uses Link to route to the different pages, as you see here: A high-level view of the Next.js project shows how easy it is to follow as well: When you want to build out pages for the React project, you must build the component and then add it to the router. One of the more notable differences for our purposes is the First Meaningful Paint. For the returning user drop in lead is 10%. How can I improve the performance of returning user? It is a great tool to use for static sites and connects easily with the CI/CD pipeline I have set up. The development is an extremely smooth process, the file structure is beautiful and organized, and the speed is no joke. The best way to test our hypothesis is by building two applications with identical functionality and UI. We were previously developing all of our projects in Meteor before making the switch. Below, we compare React with Node js, their pros, cons, and usage so you can compare them for your proposed project. When an app is loaded for the first time, it’s loaded via SSR. Husband, Engineer, OSS Contributor, and Manager at, How to create and send push notifications in React Native, Creating a Google Keep clone with React and Firebase, Using React Native to implement a carousel, https://github.com/vercel/next.js/tree/canary/examples/with-redux. Both React and Next.js have specific things they do well. Will, I did not include Gatsby because I believed it to be a static site generator. With their help, you can start developing your ReactJS project without wasting time on the setup process, providing a basic structure template and minimal functionality. After some googling (and a few failed attempts), I found that because of the way that Next.js pre- and re-renders each page, using a store is very difficult. You set up a Next project differently, of course, but in the end you write React code. One thing that I believe needs to be clarified is that Next.js takes advantage of isomorphic/universal rendering. Again, you can find it in the repo. Next.js is one way that you can leverage React to support server-side rendering (SSR). Tôi đã luôn coi Vue là ngôn ngữ phù hợp cho việc bắt đầu. As I built my personal blog site, there were times when I had to do significant googling to resolve Next.js issues. When it comes to the tooling itself, both React and Next.js were easy to get started. That being said, there is definitely a different experience when building a project with Next.js vs. React. “using a store is very difficult”. React is a great addition to any project, and it can also scale if given the opportunity. The actual libraries that we’re using are not important; the point is to get a little closer to the weight of a normal application without taking the time to build all of that in its entirety. Next.js is a React framework built by Zeit, and according to nextjs.org: With Next.js, server rendering React applications has never been easier, no matter where your data is coming from. Additionally, the overall structure of your application is already guided by Next.js by having the pages directory to hold your containers etc. Next.js also supports static exporting, but for the purposes of this post, we are focused on that “server rendering” capability mentioned above. Whether it’s a static site or a site that leverages multiple APIs, data is an important component. The initial scaffold looks like this: The files in the pages directory correlate to the routes in your application. Next.js is very similar to the React.js we know. We just happen to be using two of the more popular frameworks out there to make that comparison. LogRocket instruments your app to record requests/responses with headers + bodies along with contextual information about the user to get a full picture of an issue. But you can’t deploy it (static exported) to Apache. With React, you can get up and running by installing Node.js on your machine and running npx create-react-app my-app. Công bằng mà nói, React cũng không khó để bắt đầu. Modernize how you debug your React apps — start monitoring for free. Now we can begin to discuss real examples of React vs. Next.js with the sample application I mentioned at the beginning. I did leverage SSR with CRA though, so I’d be interested to know how CRA with SSR compares to Next.js. Redux is great because it scales a common method for working with your application’s state. If you’re interested in understanding performance issues in your production app, try LogRocket. Let’s unpack that question with some data, but first, we need to understand what exactly we are comparing here. Next.js was created on top of React in an effort to build an easy-to-use development framework. Next.js vs Gatsby vs create-react-app. The client’s browser will be accessing the applications from Boulder, CO, USA. Next.js, Gatsby, and create-react-app are amazing tools we can use to power our applications. Mobile devices generally have less processing power, so heavy JavaScript file parsing and expensive rendering can degrade performance. Both projects work and should only … Interesting, thank you for sharing! It was developed by Vercel (formerly Zeit) and makes use of many of the popular features of React. This is a major reason why we have the leading libraries and frameworks today. The linked Walmart Labs article is excellent but it’s important to remember it’s from 2017, and they call out synchronous SSR as a bottleneck with renderToString. With React, this is a matter of defining a store and then building flows throughout your application. Afterwards, CSR kicks in, giving you the best of both worlds. This makes your life easier because you’re writing less code, and the project is easy to follow. The Benefits of Server Side Rendering Over Client Side Rendering, https://googlechrome.github.io/lighthouse/viewer/, Design patterns in Node.js: A practical guide, Creating a Google Keep clone with React and Firebase, Using React Native to implement a carousel, Drag the downloaded files into the Lighthouse Viewer in Chrome. The developer experience is what makes engineers love what they do. With React, you can also rely upon a great community of developers that have created content in blog posts, YouTube videos, Stack Overflow, and even the React docs themselves. React also has a similar setup, with multiple tutorials that explain the basics. We built two nearly identical applications, one that uses client-side rendering with Create React App and one that uses server-side rendering with Next.js. The process of creating actions, reducers, selectors, and side effects scales well no matter what your application might be doing. In my sample project, if you go to the nextjs folder and the episodes.js page, you’ll see that information on The Mandalorian episodes is actually constructed by the call to getStaticProps, so the actual retrieval of the data only happens when the site is first built: Beyond the basic functions we’ve covered here, you also eventually will need to do something more complex. Let’s start our experiment with a question: Does SSR improve application performance? @thegoldenshun. Next.js provides all features that just pure React is lacking of, making it feature-ready setup to face Angular in the "React vs Angular" debate. https://logrocket.com/signup/. Based on these results, it can! Observations: The display of non-image content and the application becoming interactive is the same with both examples (< 1 second) The display of image content is delayed with Next.js (1.3 seconds) as compared to CRA (< 1 … 2789. LogRocket is like a DVR for web apps, recording literally everything that happens on your site. This is awesome. Good call out! There are a few folks that have made implementations of Redux with Next.js, but it’s not as straightforward as what you’d see with a vanilla React app. You can learn more about fetching data with Next.js in their docs. However, the team members of Next.js are themselves very accessible in the open-source world. I work professionally as an engineer, but the professional environment doesn’t always lend itself to the best developer experience. Are you a fan of the NEXT.js framework by the Vercel team?. Interesting that Gatsby is not included in this. Static sites will be more performant, but this post was intended to cover applications that require dynamic data. With it’s client side re-hydration it’s pretty solid for building web apps as well as static sites. I realize that would be a more extensive benchmark to build out though. But this is all for new user. When it comes to more advanced features like Redux or pre-rendering, both React and Next.js have tradeoffs. The Lighthouse results from our simulations showed better metrics in the Next.js application in all significant categories, especially First Meaningful Paint (87.69 percent decrease), First Contentful Paint (87.69 percent decrease) and Time to Interactive (27.69 percent decrease). They should because they mimic the diagrams included in the Hypothesis section, where we postulated that SSR can deliver HTML to the browser faster than CSR. This post compares the developer experience of Next.js vs. React. I liked it so much, that I even rewrote my personal blog using Next.js (check out my post on it). The LogRocket Redux middleware package adds an extra layer of visibility into your user sessions. When you want to build pages for the Next.js project, you just add the page to the pages folder and the necessary Link to the Header component. The distance between Boulder and Sydney is 8,318 mi (13,386 km). Your root page should thusly be called index.js. The code for the two apps is available in my GitHub. all come from a UI component library called Mineral UI. This will scaffold out a project that already has a pages folder for the pages or routes and a public directory that hosts your assets. LogRocket is like a DVR for web apps, recording literally everything that happens on your React app. With Next.js, there is less in the way of formal tutorials and more in the way of GitHub issues and conversations. This time, let’s take a look at Create React App (CRA) vs Next.js. Next just does the rest for us. Let’s unpack that question with some data, but first, we need to understand what exactly we are comparing here. For more about React on a high level, check out the official React documentation. Again, for the purposes of this post, we are paying attention to the term “single-page.”. React and Next.js both provide great developer experiences in their own way. Lighthouse also helps us visualize these differences: Do the visuals above look familiar? They all have React under the hood, powering the entire development experience. CRA is a tool that gives you a massive head start when building React apps. With that in mind, when optimizing for performance, it is important to consider both network and CPU limitations. Whatever, how do you justify that excessive DOM size? Right out of the box, Next.js provides things like pre-rendering, routing, code splitting, and webpack support. Senior Web Architect intensely focused on fast teams and fast apps I migrated my website(https://m.truebil.com) from CRA to Nextjs. React has already established itself in the industry but Angular is relatively new to the game. For more on Next.js, check out the official Next.js documentation. If you look in the react folder in my sample project, you’ll see the EpisodesPage component uses a Redux action to retrieve the episodes data, as you see here: The Redux action retrieves the values from a local file: With Next.js, you can leverage its built-in data fetching APIs to format your data and pre-render your site. Next.js is probably the most enjoyable React framework our team could have picked. When I say “developer experience” here, I mean to say what it’s like for developers to actually do the task. Let's first say what they have in common. In a perfect world, you’d find yourself on a great team of engineers with a great product, a strong user community, and powerful tools. Building pages with React requires you to create a component and then pull in React Router to orchestrate transitions in your site. Walmart Labs published a great post titled, “The Benefits of Server Side Rendering Over Client Side Rendering.” They also provide some excellent diagrams that demonstrate the fundamental difference between SSR vs. CSR performance. React is easily extendable and can include features like routing as well as state management patterns with libraries like Redux. Recently built http://www.growable.io with Gatsby and the performance wins out of the box are crazy . In the real world, you find some of that, but usually one (or more) of those is lacking. Modernize how you debug your React apps — start monitoring for free. What are the performance differences between Next.js and Create React App? 1436. Within the pages directory, you’ll see an index.js file, which is the entry point of your application. One of the first things I did was see if I could do this in my project with Next.js. According to Google’s First Meaningful Paint docs: This audit identifies the time at which the user feels that the primary content of the page is visible. Additionally, you can be more crafty with some of these APIs and generated assets at build time like RSS feeds. The LogRocket Redux middleware package adds an extra layer of visibility into your user sessions. We opened our experiment with a question: Does SSR improve application performance? Fortunately, Chrome provides a dev tool called Lighthouse, which makes it easy for us to step into the shoes of our users and understand their experience. I’m already aware with the benefits of Nextjs on CRA. While plain React either renders as a true Single Page Application—much like an phone app on the web—or renders routes with the help of a router component, Next.js ships with an internal routing mechanism. Our work with Next.js comes out much faster than if it was built on pure React or frameworks alike. Vue. Both React.js and Node.js are different technologies used to develop different parts of a web app. We will get to what the ThemeProvider and other components are in a moment. The performance of React vs … React is minimal in its footprint but can be customized for almost any project. Routing: React vs Next.js. You can find this under the Audits tab in Chrome DevTools. One of the more common patterns you see with React applications at scale is to use Redux. The code differs in how the data is fetched from the API, however: getInitialProps is a special function that Next.js uses to populate the initial data for a page in Next.js.
