Difference between Svelte, Vue and React

Technical advancements are enabling businesses and humans alike to experience the services in a much more convenient mode. However, there are multiple leaps and bounds to be crossed to include technical advancement into mainstream business. Today, we have brought a trending framework- Svelte, and how it is paving the way for a revolutionary frontend ecosystem.

A ubiquitous fact- Technology is ever advancing, giving rise to multiple innovations at large!

In this realm, the web and app development fields have evolved tremendously. But have we ever wondered what goes in the background of these technical blessings?

Well, to sum up- apart from coding there is frontend and backend that goes largely and color the canvas.

Henceforth, it is equally mandatory to keep a strong check on the upcoming advancements painting the town blue. 

In this blog, we are going to bring your attention to the prominent changes brought into practice with Svelte- the new kid on the block!

This frontend framework has the required aspects that can redefine the face of frontend structure from every bit possible.

Curious about what more this framework entails, and what is the Difference between Vue, React, and Svelte?

Hang on!

We have got you covered…just scroll ahead and spill the magical beans of Svelte.

What is Svelte?

At a basic level, you could think of Svelte as a frontend user interface (UI) framework akin to React, Vue, etc. 

It was designed to address some of the common issues that developers face when building large-scale applications, such as performance and bundle size. 

Unlike traditional frameworks, Svelte shifts the heavy lifting from the client’s browser to the build step, resulting in smaller, faster, and more efficient applications. 

It compiles the application code during the build process and eliminates the need for a large runtime library.

It results in making the final bundle size significantly smaller compared to other frameworks with faster load times.

At the same time, you cannot ignore the reactive programming model it possesses which simplifies managing state and updating the DOM…leading to cleaner and more maintainable code.

What makes Svelte DIFFERENT?

To help you understand it better, let us dive a little deeper into Svelte’s origination!

Svelte is a popular JavaScript framework that was created by Rich Harris, a developer and graphics editor for the New York Times. 

Since its inception, it has gained significant attention and has been widely adopted by developers due to its unique approach to building user interfaces. 

Unlike other frameworks such as React or Angular, Svelte shifts the work of rendering components from the runtime to the build step. 

It compiles the components into highly efficient and optimized JavaScript code.

Whoa! That’s incredible!

But wait, there is much more to be explored.

Comparing Svelte to React and Vue

Being a new framework, there are many apprehensions associated with Svelte, thus, it is highly recommended to understand Svelte performance with other ranking frameworks.

Let’s get started!

Build over browser

Svelte takes a different approach from other frontend frameworks by doing as much as it can at the build step—when the code is initially compiled—rather than running client-side.

With such an approach, it enables more efficient and performant applications, as the heavy lifting is done ahead of time. 

Furthermore, it compiles the code to generate highly optimized JavaScript that runs directly in the browser.

Consequently, it lets the application not rely on a large runtime library and get smaller bundle sizes and faster load times.

Installing Svelte

To create a Svelte app, you install the Svelte repo on your machine and write Svelte code.

It is a small, super-fast JavaScript framework that compiles your code down to efficient, standalone JavaScript modules. 

It takes a different approach compared to other frameworks like Svelte vs Vue vs React. 

Instead of running in the browser, Svelte compiles your components to highly optimized JavaScript and only updates the DOM when necessary.

Authoring Svelte components

With few exceptions, Svelte code is entirely browser-readable HTML and JavaScript. 

It is designed to be a lean framework that compiles away during the build process, resulting in highly optimized and efficient code execution. 

Incorporating reactive statements directly into the markup, Svelte simplifies the development process and enhances the overall performance of web applications.


The Svelte version is the shortest, both in terms of line count and character count, and was spellchecked and edited for clarity and professionalism. 

It is now a full four sentences that build on the previous paragraphs, if there are any, and flows naturally. 

Thus, it provides a concise and efficient solution for creating web applications.

User Interfaces

Svelte is a modern JavaScript framework that offers a unique approach to building user interfaces. 

Unlike JSX, which is React’s de facto templating language, Svelte allows developers to write HTML wherever they want, with all its attributes intact. 

This flexibility makes the markup in Svelte components more intuitive and expressive. 

It optimizes the compilation process by converting the declarative code into efficient imperative code during build time.


Svelte and Vue 3 are two popular front-end frameworks that offer a unique feature — the ability to forgo the requirement of wrapping markup in a single element. 

This flexibility allows developers to write cleaner and more concise code, without the need for unnecessary divs or wrappers.

In Svelte, the entire template is compiled into highly efficient JavaScript code, eliminating the need for a virtual DOM. 

On the other hand, Vue 3 introduces a new Composition API, which provides a more flexible and reusable way to organize and manage the state of a component.

Svelte has the ability to include any otherwise valid markup inside `#if` blocks without the need to tie them to an element. 

It enables more expressive and intuitive code, as developers are not limited to a specific structure or syntax. 

By enabling this freedom, Svelte empowers developers to create dynamic and interactive user interfaces with ease. 

Form Bindings

Both Svelte and Vue are powerful JavaScript frameworks that offer developers the convenience of two-way data binding. 

This means that when either the input or the value changes in the framework, the other automatically updates to reflect that change. 

This feature is highly advantageous as it saves developers from manually updating both the input and the value every time a change occurs. 

Leveraging two-way data binding, developers can streamline their workflow and ensure that their applications are always in sync with user input.


Writing the React expression can be challenging compared to Svelte. 

React, being a JavaScript library, requires a deeper understanding of JavaScript fundamentals and the component-based architecture. 

This means that developers need to have a good grasp of concepts like props, state, and lifecycle methods. 

In contrast, Svelte offers a simpler syntax and a more concise way of writing components.


Svelte allows developers to write loops directly within the markup, without the need to tie the loop to any particular elements or map over an array. 

It mitigates the requirement of manually keying each item in the loop, making the code more concise and efficient. 

By seamlessly integrating loops into the markup, Svelte offers a streamlined approach to building dynamic user interfaces. 

Similar to single-file components,.svelte files keep the component’s logic, markup, and styles all together. 

This approach makes it easier to manage and organize the code, as everything related to the component is in one place. 

It improves the development workflow, while removing the need to switch between different files to make changes. 

With .svelte files, it becomes easy to integrate JavaScript logic with the component’s markup and styles, resulting in more concise and readable code.

Easy class binding

Svelte is a powerful JavaScript framework that provides developers with a streamlined approach to building web applications. 

It offers a wide array of features and benefits that make it an attractive choice for developers of all skill levels. 

One of the standout features of Svelte is its easy shorthands for class binding, prop passing, and event modifiers. 

These shorthands, when you hire front-end web developers, enable them to write cleaner and more concise code, reducing the amount of time and effort required to create and maintain their applications.


One of Svelte’s notable strengths is its robust built-in API, which eliminates the need to rely on external libraries or hand-code visual transformations. 

With Svelte, developers can effortlessly create dynamic and interactive user interfaces without the hassle of managing additional dependencies. 

CSS in Svelte

To add styles to a component in Svelte, it requires to create a new CSS file and import it into the Svelte component. 

This allows to separate the styling from the logic of the component, making it easier to manage and maintain. 

Once imported, developers can apply styles to the component using regular CSS syntax, such as selecting elements or using class and ID selectors. 

It also offers a scoped styling feature that ensures styles only apply to the specific component they are scoped to, preventing any unwanted conflicts with other components or styles in the application for a Web Application Development Company.

Conditional styling

It is a crucial aspect of any web development framework, and Svelte offers a remarkably straightforward and efficient solution. 

With its simple shorthand and intuitive syntax, Svelte makes implementing conditional styling a breeze. 

Whether developers want to change the appearance of an element based on user interactions or dynamically modify the visual representation based on data changes, Svelte provides a seamless way to accomplish these tasks. 

In comparison to other frameworks, the code for conditional styling in Svelte is concise and easy to understand.

Props and component communication

To create a prop in a Svelte component, developers need to simply create a variable using the export keyword. 

This allows the variable to be accessed and modified outside of the component. 

Props are useful for passing data from a parent component to a child component, enabling communication between different parts of the application. 

By defining props, developers can customize the behavior and appearance of their Svelte components based on specific requirements or user input.

Community base

Svelte, a modern JavaScript framework, has been gaining popularity in the web development community.

While React and Vue.Js Development Services have large ecosystems with abundant resources for developers, Svelte stands out with its unique approach. 

However, some developers may perceive Svelte as having a comparatively smaller ecosystem. 

Nevertheless, this should not deter them from exploring its potential and benefits.

Will Svelte scale?

The advantage of Svelte’s approach lies in its ability to compile components during build time, resulting in smaller bundle sizes and faster performance. 

However, there are cases where this advantage may be neutralized, and it becomes more efficient to build with a different framework. 

One such scenario is when working on large-scale applications with dynamic content that frequently changes. 

In these cases, the overhead of compiling components during build time can outweigh the performance benefits, as the compilation process needs to be repeated each time content is updated.

Final Thoughts

With an incredible set of features standing alongside Svelte, it is evident that Svelte will continue gaining attention from a larger userbase.

However, at the same time, based on specific development requirements, React and Vue shall also continue to be on the top list of considerations.
