海外TECH	DEV Community	React vs. Svelte	https://dev.to/northwillov/react-vs-svelte-25e6	React vs Svelte IntroductionMore and more often we hear about a relatively new web framework to develop user interfaces on web and even for mobile apps and this is Svelte I don t want to write just about this technology its pros and cons but to compare it with the most famous web framework React and whether it can be defeated by Svelte SvelteMany developers who are starting to use this technology are very satisfied Many of them want to keep exploring Svelte s depths and even support the project both financially and by making a contribution to the repository on Github But what makes Svelte stand out and make it so unique in the competition The main feature of Svelte is that it works as a compiler and not as a library Svelte compiles the code into pure optimized JavaScript and does not need to drag the entire library to the production This makes Svelte extremely fast ReactOn the other hand React a library with rich community developers and the huge Facebook corporation behind it It is currently the most popular technology within the front end ecosystem Let s compare themWhich of them is more beginner friendlyPerformanceReactivityCommunityServer side renderingBundle sizeConclusion Which of them is more beginner friendlyWhen we start learning something new we always look first and estimate how much time and effort it takes to learn that or other technology Thus the criterion Which is best for beginners is important Both Svelte and React are not difficult to learn with JavaScript basic knowledge If you take React you may need more time to study things like JSX or CSS in JS although this is not something scary or incomprehensible Below is an example of JSX syntax Hello jsimport React from react const Hello props gt const element lt h gt Hello props world lt h gt return element export default Hello Svelte on the other hand is more like a simple JavaScript application and only adds minor adjustments to HTML Here you can see an example of Svelte syntax Hello svelte lt script gt let name world lt script gt lt h gt Hello name lt h gt lt style gt h color red lt style gt PerformanceIn this comparison Svelte can be proud not only of its superiority over React but many other frameworks as well Why is Svelte that fast Unlike React Svelte does not load the entire code of the framework into the browser but instead turns the application into a light andoptimized vanilla Javascript code on build time and does not load the browser with unnecessary work Also a very bold decision from Svelte was to stop using VirtualDOM VirtualDOM is for a second almost the whole reason why React is fast and allows it to reach such speeds But what is VDOM It is a copy of realDOM that is initialized with the application in the background we specify what the interfaces should look like and React with VDOM which is ReactDOM library finds the best and most effective way to update realDOM this is also called reconciliation process or diffing Svelte is running at build time converting your components into highly efficient imperative code that surgically updates the DOM As a result you re able to write ambitious applications with excellent performance characteristics ReactivityWhat is reactive programming Every developer has its own opinion about what reactivity is for him Here is the definition I like The essence of functional reactive programming is to specify the dynamic behavior of a value completely at the time of declaration Heinrich Apfelmus via Michel WeststrateBut to put it very simply we can think about it that way when a value changes your application should react If you want your application to be reactive in React you need to add this state or useState API otherwise your application will not respond to changes in the values of your application So React is not entirely reactive But what about Svelte Svelte brings reactivity in Javascript itself It looks through your code and watches for components that depend on your variables then updates those components as the variables change This way Svelte is reactive without having to rely on a third party API In the example below we declared the reactive variable doubled which will change only when the variable count is updated so doubled is now tied to count variable The symbol in Svelte stands for Reactive declaration lt script gt let count doubled count const handleClick gt count lt script gt lt button on click handleClick gt Click me lt button gt lt p gt count doubled is doubled lt p gt Compared to React Svelte can be considered more reactive CommunityI think everyone already knows that React is currently the most popular framework which means that it has many more developers who communicate discuss and argue about this technology There are many more such developers so if you need to make a web application for a client then finding someone to write this app using React is much easier than finding someone who will use Svelte Another important thing is that React is supported by the huge Facebook corporation and does not intend to disappear in the near future Svelte when it used to be a hobby project by Rich Harris recently joined the Vercel team which is a big plus and offers great prospects for this technology Also according to the State of JS survey newcomer Svelte takes the top spot as the most loved framework React is the most wanted desired by one in four developers Server side renderingServer side rendering SSR is the process of rendering web pages on a server and passing them to the browser client side instead of sending to the browser simple HTML page with lt div id root gt lt div gt and then pushing all content to that div with Javascript as we would do it with React we are sending a full HTML page ready to be rendered in the browser with it s full initial page content This approach is good for initial page loading speed and much better SEO Also SSR pages are optimal for users with a slow internet connection because they can see the rendered HTML while the JavaScript is processing In React there s Next js Next js is a web development framework built on top of Node js enabling React based web applications functionalities such as server side rendering and generating static websites React documentation mentions Next js among Recommended Toolchains advising it to developers as a solution when Building a server rendered website with Node js On the other hand Svelte with it s SvelteKit SvelteKit is a full stack server side pre rendering application framework for Svelte that can output production builds to different environments Next js is a great tool because it manages to reduce the big fat React library into smaller chunks and has many smart design decisions but some clumsy ones as well The first or second js download is kb but SvelteKits initial js downloads are a fraction of that by having more features built in Bundle sizeOne more not less important thing is bundle size the smaller the bundle the faster the page speed React has KB of gzipped version but Svelte team did something unusual and made Svelte with only KB it is times smaller then React wow ConclusionAt the end of this comparison it may seem that Svelte is the winner and many experienced developers say that the future is behind it But it has to be taken with a pinch of salt React is a good technology with a large community and for Svelte to overshadow it it still has a lot to grow and develop It will be good advice to get familiarize with Svelte and get something new out of it But as of the choice between Svelte and React in business will surely fall on React	2022-05-22 13:25:34
