How To Install Sweltejs ?

In this article, we will briefly introduce you to the Svelte framework. We will see how Svelte works and what makes it different from the rest of the frameworks and tools we have seen so far. Then we’ll learn how to set up our development environment, create a sample application, understand the project structure, and see how to run it locally and compile it for production.
At a minimum, it is recommended that you be familiar with the basic HTML, CSS, and JavaScript languages ​​and have an understanding of the terminal/command line. Svelte is a compiler that generates minimal and highly optimized JavaScript code from our sources; you will need a terminal with node + npm installed to compile and build your application. Goal: Set up a local Svelte development environment, build a basic application, and understand the basics of how it works.
Svelte offers a different approach to building web applications than the other frameworks covered in this module. While frameworks like React and Vue do most of their work in the user’s browser while the app is running, Svelte offloads the work to compile time, which only happens when the app is built, producing highly optimized vanilla JavaScript. The result of this approach is not only smaller application packages and higher performance, but also a more accessible development experience for people with limited experience with today’s tool ecosystem. Svelte strictly adheres to the classic HTML, CSS and JS web development model, adding only a few extensions to HTML and JavaScript.
It may require learning fewer concepts and tools than some other framework options. Its main disadvantage at the moment is that it is a young framework: as such, its ecosystem is more limited in terms of tools, support, plugins, clear usage patterns, etc. But its advantages should be enough to keep you interested in learning it.
Note. Svelte recently added official TypeScript support, one of the most requested features. We will see this later in this tutorial series. We recommend that you follow the Svelte tutorial for a really quick rundown of the basics before returning to this series of tutorials to learn how to create something more detailed. Completion should take about 30 minutes.
Svelte can be used to develop small interface parts or entire applications. You can start from scratch by letting Svelte manage your user interface, or gradually integrate it into an existing application. Web applications designed for low-power devices: Applications built with Svelte have small packet sizes, making them ideal for devices with slow network connections and limited processing power. Less code means fewer KBs to load, parse, execute, and store in memory.
Highly interactive pages or complex views. If you’re creating data views that must display a large number of DOM elements, framework-related performance improvements require no runtime overhead, ensuring user interaction is fast and responsive. Onboarding people with basic web development knowledge: Svelte has an easy learning curve. Web developers with basic knowledge of HTML, CSS and JavaScript can easily understand the Svelte specification and start building web applications in a short time. Server-side rendering, code-splitting, file-based routing, and offline support. Also, there is Svelte Native, which allows you to create native mobile applications.
As a compiler, Svelte can extend HTML, CSS and JavaScript to generate optimal JavaScript without any runtime overhead. Extend HTML to allow JavaScript expressions in markup and provide directives for using conditionals and dumbbell-like loops. It extends CSS by adding a scoping mechanism that allows each component to define its own styles without risking conflicts with other components’ styles. It extends JavaScript by reinterpreting certain language directives to achieve true responsiveness and facilitate component state management. The compiler only intervenes in very specific cases, and only in the context of Svelte components.
