Vercel has recently announced the latest version of its React-based web framework- Next.js 10. The latest version comes with automatic image optimization as well as user-analytics support to help businesses scale-up their website performance and SEO game. Automatic Image Optimization Image optimization is necessary to deliver a first-class experience to the end-users interacting with the website. It serves a plethora of benefits and some of them have been highlighted below: Improves the loading speed of the pages Better search ranking of the website pages Allows better conversions and engagement Reduces the stress on the server It’s generally a little complex job for a developer to execute the tasks enabling image-optimization because a lot of factors have to be considered in this process like size, weight, and format. Also, the complicated building tools used for image optimization often do not recognize the user-submitted images that arrive from an external data source. As a result, the possibility of optimizing ‘all of the images’ is reduced down to zero. However, the automatic image optimization in Next.js 10 can relax the burden from the shoulders of developers, help them to easily achieve seamless image optimization, and make their jobs easier at the end of the day. The latest Next.js 10 version makes it possible to optimize mages and serve them in next-generation image formats like WebP, if the browser supports it. This prevents sending large images to the devices having a smaller viewport. Automatic image optimization can also optimize any image source even if the image has been hosted by an external data source. The outcome is an automated image optimization solution, easing the developer’s workload. Most importantly, Next.js 10 renders the images in such a way so that the are not affected and the user-experience is magnified. core web vitals The developers can replace the HTML tags with a React-based image component for improving the page responsiveness. To add the images to the application, the developers can import the ‘next/image’ component as shown below: The ‘next/image’ component provides the above performance as default. With the help of this component, the images automatically become responsive and are lazy-loaded as well. You can use available to the ‘next/image’ component like ‘src’, ‘width’, ‘height’, etc., but apart from that, you can also custom configure the image optimization for fulfilling more advanced use cases with the help of ‘next.config.js’. If no configuration has been provided, then the default configuration shall be used which looks like this: various properties So, if a particular property has been missed from the above configuration like ‘imagesizes’, then such property shall pick the default from the above. What this means is that a developer will only have to configure those properties that they want to change. Next Level User Analytics in Next.js 10 To upgrade the performance and speed of a website, it’s important to have access to reliable analytics. Analytics examines how users are interacting with the website and this data helps to hunt down the areas that need improvement for enhanced web performance and user experience. Also, when it comes to user analytics, then every website should metrics because it can help in not only improved user-experience and speed but better search ranking as well. The core web vitals have three metrics that provide real-world and actionable insights: set goals for improving the core web vitals LCP (Largest Contentful Paint) FID (First Input Delay) CLS (Cumulative Layout Shift) Data analysis is important only if it is based on real-world insights like core web vitals. If it is not, then the data won’t be of much use in the decision-making process. In Next.js 10, generating real-world analytics report is an easy job. The custom app component can be created and the ‘reportWebVitals’ function can be defined for measuring core web vital metrics and even custom metrics. The ‘reportWebVitals’ function can be defined as follows: It should also be noted that the user analytics feature of Next.js 10 allows continuous measurement of data instead of a one-time measurement so that the marketers can have access to the updated insights. Not just this, but the user analytics from Next.js 10 records the data measurement from the actual devices that are being used by the website visitors instead of relying upon the development device. Next.js 10 offers next-level user analytics to help developers: Focus on the entire picture Gain a deep understanding of the target audience base Assess how a website performs for the target users How can ImageEngine act as a Catalyst for Further Advancement in Next.js 10?
