Svelte: Progressive JavaScript Framework for Fast UI Building
A high-performance framework for building user interfaces, compiling components into optimized vanilla JavaScript
What is Svelte?
Svelte is an open-source JavaScript framework that is used for building web applications and user interfaces. It was created by Rich Harris and released in 2016.
What makes Svelte unique compared to other popular frameworks like React or Vue is that it compiles your components into highly optimized vanilla JavaScript code instead of using a virtual DOM. This means your apps end up with better performance since there's no overhead from a runtime library.
Some key features and benefits of Svelte:
- Extremely fast performance since there's no virtual DOM
- Small bundle sizes after compilation so apps take less time to load
- Reactive declarations allow you to update variables whenever related values change
- Easy to pick up for those with HTML, CSS, and JavaScript skills
- Integrates well with various common tools and frameworks
Svelte shines for building component-driven user interfaces, especially ones that require high efficiency and speeds. Many developers choose it over traditional options like React or Vue when performance is critical. Its small size also makes it a good choice for embedded devices and constrained environments.
While smaller in community size compared to alternatives, Svelte usage continues growing rapidly thanks to its focus on compiling away framework overhead for faster apps.
