Introduction to Svelte vs Vue
Svelte vs Vue is defined as, the svelte is a JavaScript web framework which is used to building a fast web application, and it is a free and open-source front end compiler, it was developed by Rich Harris in 2016, many software companies are using it as a frontend framework because it offers many things so that developers has fewer complications, whereas, the vue is an open-source progressive JavaScript framework which is used for building user interfaces and single-page applications, it uses high decoupling that allows developers to create the user interfaces progressively and it was developed by Evan in 2014.
Head to Head Comparison between Svelte vs Vue (Infographics)
Below are the top 11 differences between Svelte vs Vue:
Comparison Table of Svelte vs Vue
| S.N. | Svelte | Vue |
| 1. | It provides a JavaScript web framework to build web applications, it is a tool for compiling components. | Whereas, it is a JavaScript framework that builds user interfaces and single-page applications. |
| 2. | It is a JavaScript compiler, not a framework. | And, it is a JavaScript framework. |
| 3. | It is faster in performance. | Where its performance is slower than svelte. |
| 4. | It can build high-performance web applications. | Whereas, it can build small as well as enterprise-level applications. |
| 5. | By using it we can build boilerplate-free components by using Html, CSS, and JavaScript. | Whereas, by using it we can build multi-page as well as single-page applications. |
| 6. | As it is fast and cannot be able to run in a browser without a compilation step. | On the other hand, it is a run-time-based application. |
| 7. | Both svelte and vue have easy syntax but svelte is much favorable and it is easy to use. | Whereas it is not easy to use as compared to svelte also not favorable. |
| 8. | It has declared variables so that it can automatically update our data. | Where, while using vue we have to wait for changes to be reflected in the virtual structure. |
| 9. | Svelte is stands without any support. | On the other hand, it has been supported by Google. |
| 10. | This is not flexible. | Thus, in this framework, the developer can create directives so that it is unique and flexible. |
| 11. | It offers testing libraries means it has special testing abilities, and that shows the great test result. | Whereas, it has ordinary testing abilities |
Key Differences of Svelte vs Vue
Let us see some key differences:
Performance
Now let us compare the most important feature that is the performance between svelte and vue, the svelte is a compiler that is capable of producing and simultaneously optimizing the code at only one step so that the performance it is enhanced and it does not use the DOM so it helps to decreases the resulting runtime so that user can enjoy smooth transitions and hence it provides extraordinary performance, whereas, when we compared the performance of svelte with vue then we observe that they are very different, as we see above svelte does not use DOM here vue uses the virtual DOM. There is another difference between them is lazy loading, it is a strategy that allows us to defer the rendering of non-critical resources until the user needs them especially due to this the page loading will be done faster. The svelte has a percentage score more than vue. The difference in performance is not noticeable for lightweight applications and that only detectable in big applications.
Application architecture
The comparison of architecture between svelte and vue is, the svelte can provide a page directly like vue, as it uses existing JavaScript to provides the page and it generates the components of the application by using its compilation features, on the other hand, the architecture of vue is rather different, it uses a view model method as its last model which is based on two-way data binding in MVVM model, it is a template that appears to get limitations about MVC and MVP patterns. Where M is the model which has the business logic of the application, V is the view of the user interface, VM is the view model which contains the logic for building the user interface. The vue architecture contains Filters and Directives, in which filters are used for performing the common tasks of text formatting and directives contains the block of codes so that developers can use DOM elements in the web applications. The architecture it is more unique and flexible because it has the ability to allow developers to create customized directives.
Testing abilities
Let see the difference that how easier they are to test, the svelte has more contribution of small size libraries and it has fewer computations which are not complicated, by considering it we can write more testable code in svelte than the other frontend frameworks, the frontend framework is all about how the user feels and interact with our web application. As svelte generates more testable code so it is more business-friendly, it offers the testing library by pushing towards the writing of unit test cases, whereas, vue has ordinary testing abilities but testing is straightforward as it is still rising, it does not exclude the testing capacity of code as well as it does not offer luxurious tools. The unit testing of vue is somehow similar to the other frameworks like Jests, Mocha, or Chai. Vue recommends some of the libraries that are Vue testing library and vue testing utils.
Application size
The svelte creates the smaller sizes applications and it is recognized by the most accessible JavaScript component library and it is used to run the development more productively, whereas, vue is the lightweight framework and the size of the applications is not as heavy as compared to the other frameworks. The size of its application is between 50 kb to 100 kb, which is not more.
Conclusion
In this article, we can conclude that svelte shows great testing results as compared to the vue but it is not easy to choose between them, it depends on the exact business idea, and we have seen some comparison differences between them and some key differences to show how they differ from each other.
