However, after the release of version 3 in 2019, Svelte suddenly started becoming a buzzword in the developer community. The Stack Overflow Survey 2021 revealed that Svelte is now the most loved web framework. It has also garnered over 55.7k stars on GitHub.
How did it become so popular so soon? What is so special about Svelte that the majority of developers love it more than other web frameworks?
Before we get to the answers, let’s first understand what differentiates Svelte from other popular frontend frameworks.
When frameworks like React and Vue were launched, the web development ecosystem was thrilled with their virtual DOM feature. It was a new, more efficient way to optimize rendering changes in a web app.
With virtual DOM, you can create a memory-only version of the real DOM in your web app. Whenever there is a change in the state of your app, the changes in the UI are first shown in the virtual DOM while the actual DOM stays the same. Then, the framework compares the new virtual DOM with the real DOM, observes the changes between the two, and finally renders only the changed elements on the UI.
By doing this, you ensure that the entire UI doesn’t need to be re-rendered. Hence, the web app with a virtual DOM results in faster performance.
However, with time, it became evident that even creating a virtual DOM and comparing it with the actual DOM is quite time-consuming. There was still scope to improve things further and the creators of Svelte took that opportunity.
Enter Svelte – A Compiler
Rich Harris, the creator of Svelte, is a well-known personality in the developer community.
As a compiler, Svelte ensures that it compiles the application code at build time. So when there is a change in the app state, the browser directly receives the pre-converted Vanilla JS code instead of having to do all the work by itself.
In addition to reducing the work that the browser has to do, Svelte also ensures that there aren’t any shipping runtime or abstraction layers between the browser and the app. It’s almost as if the framework isn’t even a part of the app after the build process. That is why Svelte is also popularly called ‘the disappearing framework.’
Key Advantages of Svelte That Make it A Developer-Friendly Framework
In fact, as proven by the Svelte creator Rich Harris, you need to write 40% less code to make a component using Svelte, as opposed to using a framework like React. This improves the developer’s productivity drastically.
Secondly, it’s much easier to bind classes and variables in Svelte and you don’t need to create custom logic every time you bind classes.
Future of Svelte – What Does it Look Like?
Svelte is an efficient front-end framework that helps build incredibly light and fast web applications. The concept of true reactivity in Svelte has already garnered a lot of attention from the developer community.
For now, the Svelte community is small but growing steadily. While many small to medium-scale apps have benefited immensely from Svelte, the framework is yet to be evolved in order to facilitate the efficient development and performance of large, complex apps.
