The Svelte framework is a new way to develop websites and apps. It’s lightweight and easy to use, making it perfect for those who want to create fast and responsive web applications.

Introduction to Svelte Framework

Svelte is a component framework that compiles your components at build step (using Rollup) into highly efficient imperative code that updates the DOM. It’s the equivalent of React or Vue, but with much smaller resulting bundles.

Today, most component frameworks deal with state management by re-rendering the entire component tree on every change, even if only a single node has changed. This wastes valuable resources and can lead to Jamstack in complex applications.

Instead of virtual DOM diffing, Svelte writes code that surgically updates the DOM when the state of your app changes. This means that apps built with Svelte are fast by default, and you don’t have to worry about wrapping your head around a built-in virtual DOM API. And because Svelte components have no dependencies, you can ship them as stand-alone packages, which is great for compatibility with third-party libraries and tools.

  • Write less code
  • No virtual DOM
  • Truly reactive

What is Svelte.js?

Svelte is a component-based JavaScript framework similar to React and Vue.js. But unlike those frameworks, it embraces a brand new approach to building user interfaces.

With Svelte, you write components in a format that is very similar to writing HTML, CSS and JavaScript all together in one file. Then, when you build your app for production, your components are compiled into highly efficient vanilla JavaScript code that eliminates the need for any kind of runtime library, like React or Vue.

This approach has a number of benefits. Firstly, it can give you a huge performance boost because there is no need for the browser to download and run a larger JavaScript library just to display your app. Secondly, it can make your code more maintainable because you are not relying on any external dependencies.

Svelte also provides first-class support for TypeScript, which can help you catch errors before they happen. And last but not least, Svelte comes with its own set of tools and best practices that can make development faster and easier.

Why use Svelte?

There are many reasons to develop with the Svelte framework. The main benefits are its small size, its ease of use, and its speed.

Svelte is a modern framework that uses a unique approach to development. Rather than relying on large libraries, it compiles your code at build time, so you end up with leaner, more efficient code. This also means that you don’t need to spend time loading large libraries into memory, which can improve performance.

Svelte is also very easy to use. It uses a syntax that is similar to HTML, so it is easy to pick up for anyone who has experience with web development. And because it doesn’t rely on large libraries, there is less code to write, which can save you time in the development process.

Finally, Svelte is fast. It compiles your code down to small bundles that load quickly and run efficiently. This can improve the performance of your applications and make them more responsive.

Guide for beginners

How to get started with Svelte?

Svelte is a new framework for building fast, reactive user interfaces. If you’re not familiar with Svelte, check out the [documentation](https://svelte.dev/docs).

To get started with Svelte, you’ll need a recent version of Node.js installed on your machine. Then create a new project and install the dependencies:

```bash
npx degit sveltejs/template svelte-app
cd svelte-app
npm install
```

Once that’s done, you can run the app in development mode with:

```bash
npm run dev
```

What are the benefits of using Svelte?

The biggest advantage of using Svelte is that it helps developers write easy-to-understand code that is free of any framework-related boilerplate. This is because Svelte handles most of the heavy lifting for them, which results in simpler and more concise code.

Svelte also offers a number of benefits over traditional frameworks, such as:

  • Better performance: Svelte apps are typically faster than those built with other frameworks because they are more lightweight and only load the necessary code for each page.
  • Less code: Because Svelte apps require less code, they are easier to maintain and scale.
  • Enhanced developer experience: Svelte provides a variety of features that improve the developer experience, such as hot reloading and language support for TypeScript and JSX.

How is Svelte different from other frameworks?

Svelte is a component-based framework, which means that your code is organized into small, self-contained pieces. This makes it easy to create complex applications without getting bogged down in spaghetti code.

Other popular frameworks, such as React and Angular, use a virtual DOM to keep track of changes to the UI. This means that every time a piece of data changes, the entire UI is re-rendered. Svelte takes a different approach: it uses something called a DOM diff to only update the parts of the UI that have changed. This makes Svelte applications much faster and more efficient than applications built with other frameworks.

Why You don’t need Svelte?

Do you already have a working website, but a new developer persuades you to rewrite everything on Svelte? How to understand whether you need to do it? I will try to explain on a real example.

We have a site written in React about 3 years ago. Frontend specialists always persuade us to switch to a new technology to solve old problems and keep the project code up to date. But when we get a cost estimate for this work, we see the need to increase resources x10 times. It is expensive for a working project with a small team of developers. At the same time, while the code is being updated to the new framework, the development of new features will stop. Our users do not get new functionality and will wait for it for a long time.

Of course, if you have an unlimited budget – this is not a problem. You can quickly increase your Svelte team by outsourcing. You will also have to replace your team or train them in new technology.

For example, for a SaaS startup that generates 10 thousand dollars a month, this solution is not acceptable. But for a rhubarb company with 50 thousand dollars or more should be enough resources to hire 2 developers.

Conclusion

After looking at the pros and cons of each framework, it’s clear that there is no right or wrong answer when choosing a front-end framework. The best solution is to choose the framework that best suits your needs.

If you’re looking for a lightweight solution that won’t require much development time, Svelte may be the right choice for you. However, if you need a more robust solution that can handle complex applications, React or Angular may be a better fit.

No matter which framework you choose, the most important thing is to pick one that you’re comfortable with and that will help you get the job done.
